Overview

The KUPO RH-1000S4 is the baseline 1000 kg direct-control D8 chain hoist in the RH-1000 family. It runs at 4 m/min on 50 Hz, uses a 0.75 kW 4-pole motor, 7.1 x 20.2 mm Grade 80 EN 818-7 load chain, IP 54 protection, and a 3 m cable with 4-pin CEE red connector.

Why It Matters

This is the clean no-frills 1-ton choice when the crew does not need MSP or low-voltage motor-desk control. It keeps the stronger IP 54 non-MSP body and the slower, controlled 4 m/min lift speed for everyday direct-control work.

Key Features

• 1000 kg capacity and 4 m/min at 50 Hz, 4.8 m/min at 60 Hz lifting speed suit the intended RIGPRO hoist class.
• Grade 80, 7.1 x 20.2 mm, EN 818-7 compliant load chain gives the hoist the correct chain size for its drive system.
• Spring-loaded heavy-duty DC brake holds the load safely when power is removed or a fault occurs.
• Spring-loaded DC brake, overload friction clutch, and IP 54 chassis protection protects the drive and operator workflow during entertainment rigging use.
