Product Description
Overview
The KUPO RH-250 is the compact 250 kg BGV D8 chain hoist in the RH-series family. It uses direct voltage control, a 0.25 kW 4-pole motor, 4.0 x 12.0 mm Grade 80 chain, IP 54 construction, and a pulley type chain guide specific to the RH-250 and RH-2000 format.
Why It Matters
The RH-250 is for smaller overhead points where a full 500 kg or 1-ton motor is more than the job needs. It keeps the matt black aluminum chassis, spring-loaded DC brake, overload slipping clutch, and 360° hook suspension in a lighter 30 kg body.
Key Features
- 250 kg capacity and 4 m/min at 50 Hz, 4.8 m/min at 60 Hz lifting speed match the intended rigging workload.
- Grade 80, 4.0 x 12.0 mm load chain gives the hoist the correct chain size and pitch for its lift wheel.
- One spring-loaded DC brake provides the primary holding action when power is removed or a fault occurs.
- Direct control keeps this entry RH hoist simple and compact keeps the operator workflow clear for this control version.

Frequently Asked Questions
Is this model for direct control or central controller operation
RH-250 is direct-control only in this catalog.
How is this different from the nearest sister model
RH-250 is the entry RH-series model below the RH-500 family, with 250 kg capacity and 4.0 x 12.0 mm chain.
Can I swap to a different load chain size
No. Use the specified Grade 80 EN 818-7 load chain size for the hoist. Chain diameter, pitch, and load wheel geometry must match the hoist design.
