Case Study

Initial Situation

  • Manpower shortage
  • Lifting of long modules to top of the building
  • Portable solution that can be transported from site to site for different projects
  • Dusty environment
  • Accuracy to be within 10mm

Solution

  • Synchronised lifting function Chain Hoist
  • Light & Portable hoists made of Aluminium alloy, CNC body processing
  • Individual / Group control - 40units of Chain Hoist at once
  • Height difference of the hoists if kept below: 10mm accuracy
  • Easy & fast connection set up
  • Manpower reduce from 10 to 2

Features

  • Constant Torque inverter motor
  • Safety feature: Automatic break when power is cut off
  • Wireless transmission signal up to 100m
