Baureihe BF

progressive safety gear /BF series / EN81-20 / Sautter Lift Components GmbH / SLC

bf series

The two basic types of the BF series differ in the design of the counter-brake shoes. For type 2, the counter-brake shoe side is equipped with two additional sintered metal brake shoes. This design feature allows higher loads and higher tripping speeds in the same space.
