PINTSCH BUBENZERis certified according to
DIN EN ISO 9001:2000
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 manufacturer´sapproval 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.
