Definitions

  • the invention relates to a method for producing a counterweight for an elevator, a procedural ren for building an elevator system, a counterweight for an elevator and an elevator system with a counterweight.
  • a counterweight for an elevator serves to compensate by gravity for the weight of an elevator car and at least a part of the permissible payload. Elevator car and counterweight are coupled together such that the counterweight moves down as the elevator car moves up and vice versa. A drive must therefore only set the difference of the weight in motion.
  • a counterweight with a weight of about 2.5t For a lift with a weight of 2t and a payload of lt results, for example, a counterweight with a weight of about 2.5t.

These parts can fall into the hoistway, fall into rails, between brakes, mecha nically movable elements or electronic components. They can lead to pollution and in the worst case could cause a security risk.
  • the object is achieved with a method for producing a counterweight for a lift, which comprises the subsequent steps.
