VARIATOR ESR

Lift speed control system for hoists
and travelling cranes

This option allows reduction of cycle time (faster return speed for empty returns) therefore of FEM group duty.

Product advantages :

  • Maximum ESR speed, 1.5 times greater than standard speed
  • Productivity enhancement
  • Enhancement of load travel accuracy
  • Optimal use of work space and approach data of hook

Basic working principle
Type S (ESR) motors can be operated at full speed at up to 40% of the rated load, the max. motor speed remaining at 3000 rpm. At 20% of the load, the rated speed is the equivalent of 150% of listed speed. With nominal load, the rated speed is the equivalent of the listed speed.
