Professionalism and flexibilty characterised the brothers Franz and Clemens Schneider when they founded the company "Stahlhammer Bommern Gebr. Schneider" in 1911. They were involved in manufacturing hammer forged crane suspension tackle, shackles, chain hooks, ramshorn and single hooks, special keys and ships stern posts.
The next generation had a focus on rationalizing production processes by specialization on defined product segments in order to offer drop forged technology to mass products.
In 1973, the 3rd generation transferred the company site to Hamm. After increasing capacity with new workshops and the change to modern oil-hydraulic presses and hammers it was possible now to drop-forging parts up to 600 kgs weight.
In order to secure the future development of the company, a new generation of management entered the company with the beginning of 2007. A change of ownership and legal form of the company took place at the same time. New owner are Mr. Brandis and his two brothers, who continue to feel committed to the traditions of a family-owned company and the highest quality of our product.
The management was taken over by Dipl.-Ing MBA Thomas Brandis.
The Company changed its name to Stahlhammer Bommern GmbH.

The own drop and tools production and modern mechanical machinig processing enable us to fulfil our customers' wishes in a short time and to manufacture drop forgings up to ready-to-installed versions. When coal and steel, the traditional main point of the Ruhr-industry lost its influence, the changed needs of the market were recognized and considered. Increasingly, stainless steels are being used for forging and the range of availabel shapes has been considerably extended by the addional use of hot-pressing methods.
The name "Stahlhammer Bommern" today stands for state-of-the-art technology, flexibilty and quality.

Supporting parts and lifting parts II
In consideration of the own standard specifications of big customers and according to the demands of our clients we developed universal useable standard-sizes for single and ramshorn hooks very early.
Since the year 1943 the DIN publicated standards which always kept up-to-date and have been readily accepted by other countries because of their near-to-the practice.
For our hook production we apply to the DIN standard.
Standard hooks can be delivered as rough forgings or as machined parts with knuckle direct from our plentiful stock. We offer hooks with special lengths of shank as same as hooks with abnormal dimensions.
Hooks up to size No. 63 are manufactured as drop forged parts. From size No. 80 up to size No. 250 we forge them as open die parts. Dimensions bigger than size No. 250 can also be offered as same as laminated hooks in compliance to DIN 15407.
Hook suspensions in compliance to DIN 15411 are available direct from stock. We offer also arrangements of bottom hook blocks in compliance to DIN 15408 - 15410.

It's possible to make forgings which can usualy make only on hydraulic presses in combination with a screw press or a die hammer. Typical forgings are: flange shafts, big valves for statical Diesel-engines, axle-pipes with flange and flanged naves. Due to our flexible use by changeing the dies it's also possible to manufacture small and medium series. The big table and ram areas allow up to 6 deformation work operations and the ram stroke of 1.400 mm allows the manufacturing of long forgings.
The storage capacity of more than 100 manufacturing operations and it's archiving make it possible to get short set-up and shut downs for an efficienty manufacturing of medium lots.

We're qualified by all renowned inspection companies at home and abroad and besides we guarantee with our name.
CE-Conformity CE-Identification The CE-Identification is not a particular feature for product quality or performance of a producer. It only indicates the opinion of the producer that its machine complies to the EG machine directives. The CE-Identification is neither a quality feature nor a quality certification which is granted after a test procedure or theoretical prove from an independent certification company or public authority. The retention or the improvement of the security level in the member countries is the main intention of the EG machine directives. The existing national regulations for security and health to protect against danger, which come from machines, should be brought into line in order to allow a free exchange of machines without lowering the protection levels in the individual member countries. The CE-Identification replaces the previous product certification standards for building and equipment of the public environmental authority, the Accident Prevention & Insurance Association, the German TÜV and others. The same applies for product certification situations in other countries of the European Union (ISPESI, APAVE, etc.), which are deprived of the legal basis of product certification for building and equipment. The certification of installation situations (safety clearance etc.) will stay in the responsibility of the national security authority. The occupational safety authority are allowed to pull a product with a CE identification out of the market or to forbid the initial operation only if danger for persons, animals or goods exists. The measure entails a compulsory procedure by the European Commission in Brussels and must be decided by the European Court of Justice. Missing knowledge of the EG machine directives can shake up the operators due to deviating arguments of the different producers. For all machines, which fall under the EG machine directives, a CE-Conformity declaration has to be certified by each producer which has to be provided with each delivered machine. Components which are functionally usable only together with other components (e.g. hooks) a producer certification is required which is provided with each component. On each machine the following minimum information that must be readable and un-erasable must be provided:
• Name and address of producer • the CE-Identification • Identification of product code and type of product • if necessary: serial number
If the producer designs a machine to be used in an explosive atmosphere this indication (e.g. Protection symbols) must also provided on the machine. According to the design of the machine all for the security indispensable information have to be provided on the machine (e.g. the load capacity on hoisting devices or cranes). Hook suspensions which belong to the category of exchangeable equipment according to the EG machine directives have to be labelled as follows:
• Name of Producer • maximum load capacity • own weight • the CE-Identification
For lifting accessories with components like cable where labelling is not possible a plate or other device with the above mentioned information has to be fixed to the lifting accessory. The information must be in good readability and be fixed at a place where it can not be erased through wearout and where the stability of the lifting accessory is not reduced. CE Symbol The CE-Symbol consists of the following symbol: CE Minimum height is 5 Millimetres. A combination with other symbols like e.g. the GS-Symbol is possible under certain circumstances.
Recommendations concerning surface coating, corrosion protection and special materials. Due to the surface crack test load hooks and corresponding components are delivered with a sandblasted or blank surface. Under atmospheric influence all untreated parts will start corrosion after a short period of time. By using synthetic resin paint (for example in color RAL 9005) for the surface which will not be mechanically processed and through application of corrosion protection oil (for example Dekydrat 180) for mechanically processed surfaces the corrosion can be avoided. For transport and storage protection different anticorrosives are used. Also plastic or paint based coatings offer protection for a limited period of time (normally less than 2 years). Furthermore galvanic coatings are possible for example based on zinc. The unavoidable temperature of 500 °Celsius in the zinc basin can be detrimental to the mechanical properties of the parts due to the tempering effect. This negative effect occurs significantly only with small cross sections and with material which has a low resistance against tempering. The bigger risk with the galvanic processing as well as with hot-galvanising lies in hydrogen embrittlement. Already at the pre-treatment pickling process and during the coating process hydrogen diffusion can not totally be eliminated. Therefore we recommend as after-treatment a hydrogen diffusion annealing (dependant on size of cross-section ca. 4h at 222°C). Through this after-treatment possible reduced toughness properties of the drop forged parts or - in the worst case - brittle fracture can be avoided (please note DIN 50969). For use in sea water or for parts in the chemical industry or equivalent industries drop forged parts can be offered in stainless steel materials (for example 4401 or equivalent). Those materials are nearly antimagnetic and have less tendency to spark formation. For use in mining or in other explosive areas we recommend to use hard nickel plated parts (around 550 HV). Copper plating does not achieve the required durability. Forging spark free materials which conform to strength class M respective P is possible with complex forging processes and due to low production volume only recommendable in special cases. We offer all processes of special metal treatment in cooperation with business partners.

This standard includes safety requirements within the meaning of the “Gesetz über technischeArbeitsmittel” (Technical Equipment Safety Law) This standard has been prepared with theHauptverband der gewerblichen Berufgenossenchaften e.V, Central office for accident prevention andoccupational medicine, Bonn.
Start of validity:
This standard is valid from March 1st, 1979
1 Field of application
This standard covers all forged hook (for liftinggears) which serve primarily for mounting ofloads, e.g. single hooks, double hooks,crosshooks, support lugs, loops for laminatedhooks and so forth.
2 Scope
This standard gives instructions on the propermaintenance and in-service inspection of hooks,the aim being to improve the safety and lifetimeof the hooks.
3 Standards referred to
DIN 15401 part 1 lifting hooks, shank hooks with point, forgingsDIN 15401 part 2 single hooks, finished parts with threaded shank
DIN 15402 part 1 ramshorn hooks, unmachined partsDIN 15402 part 2 ramshorn hooks, finished parts with threaded shankDIN 15403 lifting hooks for hoists, knuckle threadsDIN 15404 part 1 lifting hooks, technical conditions for forged hooks
4 tests before putting into operation
Forged hooks shall be visually checked for it'smarking (DIN 15404, part 1, march 1979edition, subclause 4.7). Marking must be inconformance to the hooks testing certificateDIN 15404, part 1 where required. At sametime measured length y, y1 and y2 at hookaperture must be inspected by means of acalliper square.

5 Routine tests and observations
This is to avoid accidents by in time detectingof defects at forged hooks. Testing results andmeasures to fix them must be mentioned intothe testing documents (if its directed to keeptab on a test book by the employer's liabilityinsurance association).
5.1 Deformation
hooks shall be examined for any sings ofdeformation, especially on hook aperture andshank at least of once a year. For hooks acc.to DIN 15401 part 1 and 2 and DIN 15402 part1 and 2 a visually examination of the hookaperture up to size No. 5 is sufficing. By morethan 10 % widening of the admissibledimension of the hook aperture (a2) acc. to DIN15401 part 1 and DIN 15402 part 2, hooksmust be replaced. All other hooks and loopsfor laminated hooks must be replaced ifdeformation in use exceeds 10 % of the hooknominal sizes. If deformation is detected, testsaccording to subclause 5.2 must be done, too.
5.2 Surface cracks
If deformations acc. to subclause 5.1 aredetected, testing for surface cracks must beexecuted also (by an applicable procedure) orthe hook must be replaced. If it's not possibleto execute this test because the hook isbuilt-in, it must be disassembled. The surfacemust be prepared to that effect that a clearidentification of surface cracks is possible.Damages and surface cracks can me removedfree of notches as far as function, admissibledeviations and admissible wear do admit.Hooks which have non-admissible surfacecracks must be replaced
5.3 Wear
For single and double hooks takes effect, thatmore than 5 % wear of dimension h2 acc. toDIN 15401 part 1 and h according to DIN15402 part 1 isn't allowed. For all other typesof hooks this stipulation is to construedanalogues. Wear doesn't proceed 5 % of thenominal sizes. Caliper gauge accuracy sufficesfor measurement . Notches and othersuperficial imperfections shall be groundsmooth. Wear at hook nuts and locking piecesis non-admissible.
5.4 Corrosion
If the influence of corrosion can't be avoidthread and machined shank must be inspectedto corrosion notches. If reworking of corrosionnotches is necessary, inspection acc. to DIN15404, part 1 (edition march 1979, subclause5.3) must be done. A new hook nut must bemanufactured in case of non-admissible axialplay.

Designation for a double hook No. 100:Double hook DIN 15402 - RFB 100 - P
Other length than l1 to agree with order.So designation for l1 = 1500 would be:
DOUBLE HOOK DIN 15402 - RFB 100 - 1500 PPermissible deviation acc. to DIN 15402 part 1, page 3, table 3.
Execution and acceptance test acc. to the technical rules of DIN 15404 part 1.The load capacity of these hooks are in accordance to DIN 15400.
1 Field of application and purpose
This standard applies to double hooks which are used for handling equipments on ships.Hooks type A with thread are common for direct joining of the hooks with lower blockcrossbeam of the cargo purchase.Hooks type B with fork are needed by interposition of an eye for swivels acc. to DIN 82010.Hooks type C with eye are needed by interposition of a fork for swivels acc. to DIN 82008.
This standard applies for double hooks (drop or hammer forged parts) with and without nose,on lifting means and load carrying means of lifting appliances, which are used primarily forthe suspension of loads. The correlation of the lifting capacity of the double hooks to thestrength classes and driving gear groups is in accordance to DIN 15400. They are assigned tothe nominal sizes of this standard.

Explanatory notes
DIN 15 412, September 1970 edition, only dealt with the finished parts for lifting hooks Nos. 2,5 to250. DIN 15 412 Part 1 now includes the unmachined parts for lifting hook Nos. 006 to 40 and Part 2contains the finished parts for lifting hook Nos. 006 to 250.The dimensions of unmachined parts for drop forged cross pieces for the most frequently used crosspieces, particularly for serial lifting appliances, are laid down in DIN 15 412 Part 2, as are those oflifting hooks up to lifting hook No. 40.For cross pieces from lifting hook No. 50 onwards and for cross pieces with lifting hook suspensionswith devices preventing rotation and swivelling of the cross piece relative to the lifting hook, hammerforged, unmachined parts shall be used.The dimensions of hammer forged, unmachined parts for cross pieces were not specified.It is recommended that in this case the machining tolerances should be agreed in accordance with themanufacturer´s data and a square shape with b 1 should be manufactured instead of an oval shape.Up to lifting hook No. 40, drop forged or hammr forged cross pieces can be used, at the bottom blockmanufacturer´s discretion.

Hook safety latches According UVV VBG 9 a § 19 principally load hooks have to be designed in a way that an unintended loss of the load suspension devices, the lifting means or the load can be avoided. This requirement is fulfilled if e.g. safety latches are existing. Safety latches are normally mounted to the load hook with a nose. According to UVV hooks with a shank can be designed with a clamp. Welding of nose is forbidden. Hook safety latches according DIN 15106 are to be used for drop forged single hook Form GSN and GFN according DIN 15401/2 to avoid an unintended loss of the lifting means. DIN 15106 indicates that equivalent hook safety latches which are produced with a different manufacturing technology or in reinforced design for productions cranes are acceptable if the protection intention according to Chapter 2 is achieved. To meet the requirement of UVV in consideration of DIN 15106 we have designed hook safety latches which can be used for single hooks acc. DIN 15401 size no.1 to no.250, for double hooks acc. DIN 15402 size no. 2,5 to no.250, for eye hooks acc. DIN 7540 size no. 27 to no.36 and WN size no. 37 to no.42, for cargo hooks acc. DIN 82017 size no. 3 to no.16 and for cross hooks acc. WN 21061 capacity 2,5 to 10 tons. The advantage of this design consists of facts that also double hooks which have 2 mouthpieces and therefore a double risk of an unintended loss of the lifting means are covered, the latches are made out of solid steel plate, the spring is produced out of stainless steel material and a easy serviceable screw joint is used which especially for hook with a high load capacity guarantees a quick and risk less assembly. Acc. UVV ZH 1/27 functional capability of hook safety latches has to be checked regularly. Hook safety latches for load suspension devices which are intended for passenger transport are subject to rigorous obligations. They have to close and lock autonomously without spring movement. Additionally the lock mechanism has to be protected with a screw connection which is fixed with a splint. If you need these hook safety latches please ask for a quote stating the hook size.

Note for special hook suspensions with electrical isolation acc STB Form 1777 The Isolation is designed in a way that mechanical damage during operation can not occur. An unintended removal of the isolation is not possible. The design of the isolation makes sure that electrical current can not affect the roller baring. Using fabric-base laminate materials HGW 2082 absorption of moisture is avoided which can occur by using polyamides. Enough space between nut and crosshead has to be considered. To avoid electrical conductivity of the roller baring lubricant only lithium-saponifieded EP-fat should be used (ARAL Longlife Fat H or Klüberplex Be 31-502). According to the lubricant supplier the electrical conductivity is near 0. An additional isolating effect can not demonstrated. Annex table DIN 7735 Hamm, 01.April.2007
