Type EWF - Standard type with safety device (capacity: 4.5 kg to 120 kg)
by ENDO
The balancer of this series is equipped with safety features that are same as the EWS series. The exposed part of the drum is reduced as much as possible to ensure worker safety. The fall-arrest device prevents a suspended object from dropping even in the unlikely event that the spring breaks.
It also has a gauge for adjustment with respect to the suspended mass. Therefore, tension adjustment can be performed easily.
- For suspending electrical devices, jigs, tools, and materials for processed goods.
- Centering operations.
- Balancing device for various kinds of equipment.
