“When the wind of change blows, some people build walls, others build windmills.” (Chinese proverb)

Let us build windmills!

As a manufacturer of hydraulic grabs and slewing gears, we develop and produce highly specialized grabs and load sus-pension devices for miniexcavators from 800 kg to excavators with a service weight up to 400 t. We have been developing our products at the our location in Ilsede nestled between the cities of Braunschweig and Hanover for 33 years.

Our mission is to produce innovations and create products that work as effectively as possible in conjunction with excavators while delivering perfect results. To accomplish this, our design department continuously develops and refines our grabs. We incorporate the insights resulting from the required applicati-ons and experiences into our product development.

Everything from a single source for the best possible excava-tor. This is our team’s promise to you. Driven by your enthusi-asm, we look forward to more exciting collaboration projects with you.

Our grabs feature a modular design, consisting of a base unit, shells and optional accessories. This simpli-fies the configuration of tailored grabs while lowering costs. Plus, it makes changing wearing parts or even a single module very easy.

Our innovative 3-point plug-in system saves time and money when changing the shells or the base unit. This in turn saves resources and ensures that you always have the right tool at hand, even if your terrain changes.

Series RCSP

Two-shell loading grabs (P)

5The RCS-P is equipped with a plunger cylin-der featuring a piston rod on each side of the piston surface. This enables two equal active areas for retraction and extension. The volu-me of incoming and outgoing hydraulic oil is identical and the grab moves at the same speed in both directions. Oil is guided within the cylinder, so no additional hydraulic hoses are required under the DWP15 slewing gear. This prevents possible damage to the hydraulic hoses and ensures absolute synchronous run-ning without additional mechanical synchroni-zing guides.

Over 20 years of experience with fully automatic quick change systems.

Maximum efficiency and flexibility – by using optimal attachments, the machine is a versatile equipment car-rier. This enables maximum carrier utilization while opti-mizing processes.

Secure connections in a matter of seconds – simple, safe exchange of hydraulic, mechanical and electrical devi-ces from within the cab.

Integrated power supply – use of magnetic plates wit-hout manual wiring from the machine to the magnetic plate.

Maximum flexibility – all attachments continuously rota-table thanks to 360° slewing head.

Series DWP

Hydraulic slewing gears12

50

DWP slewing gears were designed for use on hydraulic attachments for hydraulic excavators as well as for mobile and stationary handling machi-nes. They perform three functions for operating the attachment:

• Continuous hydraulic rotary drive• Hydraulic rotating union • Axial as well as radial support of the attach-

ment in rotary operation

for suspended loads

Fig.: DWP26

51

The slewing gear is mounted as a complete unit, which allows the wear component to be quik-kly mounted and dismounted. All three functional units work independently. This makes it possible to replace individual components easily and econo-mically in the case of wear or damage, which can be done by personnel with standard metalworker's knowledge. In addition, the structure of the DWP protects the hydraulic system of the carrier against oil contamination from possible bearing wear or slewing drive wear, unlike compact rotators.

Fig.: DWP26

52

A combination of our slewing gears and a tailo-red magnet holder ensures secure, efficient wor-king with your magnets. The slewing gears are either available with an electric rotating union for unlimited rotary function or with a mechani-cal stop to prevent the power cord from being disconnected. Our magnet holders are also available with an OQC adapter to be able to perform this work without leaving the cab.

In combination with a SW suspension or OQC adapter, these hydraulic rotating load hooks are a safe alternative to suspending and transpor-ting compact goods without needing to use the grab in a way that is not intended. This soluti-on prevents accidents as well as damage to the grab and load.

Hydraulic slewing gears13for positionable use

The DW series is designed specifically for positional use. High axial and radial loads can be handled thanks to a generously dimensioned housing and 4-point bearings with internal too-thing. As with the DWP series, the rotary drive, rotating union and bearing functions all work independently. The slewing gears start at a load bearing capacity of 15 t and reach up to 40 t in increments.
