Electric Hoist with Frequency Inverter (GIS GPFU)

Electric hoist with frequency converter

Frequency-controlled electric chain hoists GPFU have successfully proven themselves in various applications. They are often used in very demanding working conditions with long working periods and a high switching frequency, such as shift work.

The 2 lifting speeds are infinitely programmable and can be optimally adapted to all modes of use. In addition to specially adapted speeds for precise positioning of the load, the acceleration and braking range can also be ideally adjusted to avoid load oscillation.

Standard features:

• electric chain hoist with frequency converter
• electric cranes with inverter
• adapted for applications with high switching frequency and operation in gear stages
• lifting speed up to 9.6 m/min.
• with a soft start for precise and gentle positioning of the load
• lifting and lowering the load without exceeding, accurate positioning of the load in combination with a frequency-controlled motorized trolley
• the speed and range of lifting and movement are programmable and adapted to the application
• protection class IP65
• option: motorized cart with frequency converter
• option: wireless remote control
• option: load-dependent lifting
