Abstract

Toothed belt drive system for lifts, drive machine under the counterweight countersigned example with a centrally guided car in that the car (1) is suspended 1: 1, that the counterweight (2) is 1: 2 suspended, that the drive machine (3) is suspended under the counterweight ( 2) it is arranged that the ropes (5) have no driving function and the power transmission from the machine (3) takes place through a toothed belt.

Description

  • State of the art
  • The usual lifts are designed as traction sheave lifts (accordingly EN81-1) or hydraulic lifts (according to EN81-2) built. Both systems have their advantages. The traction sheave elevator has a better energy balance, the hydraulic elevator is space-saving in design but has significantly higher energy costs. The hydraulic lifts can usually be used with technology known and used today do not convert to energy-saving traction sheave lifts.
  • solution
  • The "toothed belt drive for lifts" system is primarily intended for conversions hydraulic elevators used for "machine room-less" traction sheave elevators become.
  • Achieved advantages
  • The result for the operator from the conversion The following advantages: The electrical connection values and the power consumption become significantly smaller. The speed can be increased and the arrival times are getting shorter. The result for the operator is about 30% more funding with 30% to 40% energy savings.
  • example
  • the car ( 1 ) is suspended 1: 1 and is guided in the middle, the ropes are run over two rope pulleys ( 7 ) led to the counterweight, the counterweight ( 2 ) is suspended 1: 2, the drive machine ( 3 ) is under the counterweight ( 2 ) arranged the ropes ( 5 ) have no driving function, the power transmission from the machine ( 3 ) to the counterweight ( 2 ) is done by a toothed belt ( 6 ) with the counterweight frame with a positive plate ( 8th ) is screwed tight
