  • Description SF

    B2

    Two identical caliper halves, ready for operation,with spring packs set to nominal force and limitswitch for release control

    Main Features

    Limit switch wear control

    Options

    Sintered linings

    Complete piped supports for one or more calipers

    Hydraulic power unitsUp to 2 mm airgap between brake pad and disc

    Special seals for flame-proof fluids

    Cleaning pads

    Brake discs

    Easy, manual pad wear compensation

    Organic, non-asbestos linings

    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.

    Applications

    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.

    Operating Restrictions

    Please Note

    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 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.
