Overview
The KUPO RH-500LV is a 500 kg D8 chain hoist with low-voltage control for controller-desk operation. It combines a 0.40 kW 4-pole motor, 6.3 x 19.1 mm Grade 80 load chain, 24 V / 48 V / 110 V control, geared upper and lower limits, phase protection, and IP 54 chassis protection.
Why It Matters
Low-voltage control makes sense when several 500 kg hoists need to run from a controller instead of separate direct-control stations. RH-500LV keeps the half-ton RH platform while adding the control and protection features needed for a cleaner motor system.
Key Features
- 500 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, 6.3 x 19.1 mm, EN 818-7 compliant load chain gives the hoist the correct chain size and pitch for its lift wheel.
- Spring-loaded heavy-duty DC brake provides the primary holding action when power is removed or a fault occurs.
- Low-voltage control separates power and control for central operation keeps the operator workflow clear for this control version.

Frequently Asked Questions
Is this model for direct control or central controller operation
RH-500LV is designed for low-voltage controller operation.
How is this different from the nearest sister model
Compared with RH-500, this version adds low-voltage control, geared limit switches, and phase protection.
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.
