Integral differential pressure load limiting valve automatically prevents the operator lifting a load of more than 125% of the working load limit. Load limiter is 100% repeatable at all working pressures and does not wear or generate damaging heat.
Pendant control hoists are supplied with a mains emergency stop valve. This shuts off the main air supply to the hoist when activated.
Accurate and precise positioning of loads is standard for both toggle and pendent control models.
Fail Safe Disc Brake
Non-asbestos self-adjusting disc brake is applied automatically when the air supply to the hoist is shut off. The brake is self-adjusting for the life of the brake and can hold more than 125% of the working load limit.
The exhaust air silencer is built into the hoist gearbox housing and limits the noise level to below 85dB(A).
Grade 8 load chain ensures stringent high-speed duty cycles can be met. The load chain is in accordance with the requirements of EN818-7 Appendix B.
Assisted vane lifting ensures maximum starting torque when starting under load.
The sealed planetary gearbox ensures that the most stringent duty cycles can be met. The gears are heat treated and mounted on high strength, low friction bearings.
Ease of Maintenance
The modular design of the hoist allows easy access to internal components such as the motor, gearbox, brake and load limiter. Common parts are used throughout the range.
