The high capacity of these brakes makes them particularly suitable as secondary emergency brakeson hoist gears and on downhill conveyor belts.
Other applications are possible in material hand -ling, requiring power and compact design in eitherdirection of rotation, particularly in replacing bandbrakes.
Use of the brakes for applications with high dutycycles should be specifically indicated duringtechnical selection procedure.
Brakes of this range are tested both mechanicallyand hydraulically and are set to nominal force. This setting can only be changed by the manu-facturer. Operating conditions other than describedin this brochure require the manufacturersapproval and may influence the function of thecaliper and its components.
We supply a detailed operating manual with every order. Nevertheless,we would point out that brakes are only as safe as the servicing andmaintenance performed while they are in operation. The guarantee forthe correct functioning of our brakes is therefore only valid if the useradheres to the German DIN standard 15434 part 2 (drum and discbrakes, servicing and maintenance in operation), or to comparablestandards in his own country.
PINTSCH BUBENZER Service
This includes the verification of the brake selection, if required. A detailed questionnaire is provided for this purpose. Installation andcommissioning on site is possible by PINTSCH BUBENZER serviceengineers. Drawings as DWG/DXF files for your engineering department are available upon request.

The flow diagramshows the generalarrangement of thehydraulic power unit,including handpumpfor emergency manual release ofthe brakes.
The two solenoidvalves are switchedin parallel (redundan-cy). After the nomi-nal pressure isreached, the idlervalve switches intoidle running. Themotor is continuouslyenergized.
Pressure switch, temperature switch,heaters, level switch,stainless steel versionand other accessoriesare available options.
Hydraulic powerunits are also avail-able as two-circuitpower units, e.g. tooperate main hoistand boom hoistbrakes with onepower unit only.

With every order we supply a complete hydraulic and electric diagram according to the orderspecification.
Piping SamplesDisc brakes SF and BSC
Piping of one brakeunit one hydraulicpower unit
Piping of two brakeunits - one hydraulicpower unit
Attention: For operating two brake units with one power unit please note, that the power unit should be installedin the middle between the brakes to get almost equal pipe length on both sides (equal apply time of brakes).
