Page 9: General Description
Example 2: Ascertaining permissible load type: An electric chain hoist of the ISO Group M5 is to be used for approximately 6 hours per working day, throughout its complete service life. Consequently the electric chain hoist should be operated in accordance with the characteristics of the load type <1 light> (see table 1-1). -
Page 10: Special Models
A drilled hole is provided for both the power supply cable gland and the control cable. The lugs, or optionally the suspension hooks, are attached to the flange ring. GIS electric chain hoists are driven by asynchronous motors. For two-speed models a pole switching version of the motor is fitted. -
Page 11: Start-Up
DANGER ! 2 Start-up Mechanical adjustments may only be performed by authorised specialists. CAUTION ! Operating staff must carefully read the operating instructions of the electric chain hoists before its initial operation and carry out all checks. Only when safe operation has been established may the device be put into operation. Unauthorised persons may not operate the device or carry out work with it. -
Page 12: Load Chain
DANGER ! The protective conductor should not carry any power. With motor carriage operation, the power supply is enclosed in a terminal box of the drive motor. With the installation of a motor protector, the load plate voltage of the electric chain hoist must be observed. - Page 13 Single fall operation: The load hook (1) is connected to the chain using a shim (2). Bolt (3) installation is important for power transmission (see figure 2-6). CAUTION ! Pay attention to correct arrangement of suspension (see figure 2-7)! Grease the bearings thoroughly.

Page 14: Limit Switch
2.2.3 Limit switch The electric chain hoist is equipped with a gearbox limit switch as standard. This is also suitable for normal limit switch operation with a high degree of accuracy. The operation of the limit switches (highest and lowest hook position) must be checked during start-up. -
Page 15: Chain Bucket
2.2.4 Chain bucket Move chain out at load side until limit switch is activated Attach free end of chain to housing (see chapter 2.2.2) Attach chain bucket and allow chain to run in (see figure 2-13) DANGER ! All steel plate chain buckets must be equipped with an additional wire cable with a minimum diameter of 2 mm (see figure 2-14). -
Page 16: Service And Maintenance
During service and maintenance work, general accident prevention directions, special safety directions (chapter 0.3) as well as hazard protection instructions (chapter 0.4) should be followed. DANGER ! Service and maintenance work should only be performed on unloaded electric chain hoists. The main switch must be off. The lower sheave or hook fittings must be lying on the floor or a maintenance platform. -
