Please find enclosed our corresponding offer for an electric chain hoist with electric trolley for operation with an inverter (or frequency converter).
This device is used to control the speed of the hoist and trolley. Unfortunately we cannot offer this system with a special pendant for a step less speed control.
The speed can be pre-adjusted up to the maximum speed of the hoist and trolley. However the speed can be controlled and accelerated by keeping the button of the pendant pushed.
We are looking forward to hearing from you soon.
Thank you & best regards,
