YaleERGO 360® UT ratchet lever hoist with safety gear

YaleERGO 360® UT Ratchet lever hoist with safety gear

Capacity: 1500 – 9000 kg
The YaleERGO 360 ® UT is now also redefining the world of hoists for overhead line construction. The patented automatically acting safety gear, once more increases the safety of use.

The YaleERGO 360® UT has a unique, automatically locking safety device to prevent a sudden drop. It guarantees permanent monitoring and is active during operation as well as during inactive moments without the user having to activate it.

The system safely absorbs the load, preventing the creation of larger dynamic forces which could cause further damage. Another highlight is the possibility of being able to lift at any time – even after the safety gear has been triggered due to safety reasons.

  • Others …

REQUIREMENTS FOR THE REDUNDANT SAFETY GEAR

REQUIREMENTS FOR THE REDUNDANT SAFETY GEAR

In accordance with EN 1808 – Safety requirements for suspended access equipment, 8.9.2

  • shall automatically engage in the event of overspeed (more than 0.5 m/s)
  • the stopping distance must not exceed 500 mm
  • shall be capable of being reset
  • shall be capable of being inspected
  • shall permit lifting at any time

In any cases the load is caught exceeding a speed of 0.5 m/s.
Speeds below 0.5 m/s (corresponds to 2 km/h) are not safety relevant according to EN 1808.

Benefits & Features

AUTOMATICALLY ACTING SAFETY GEAR

The YaleERGO 360® UT has a unique, automatically locking safety device to prevent a sudden drop (patent pending). It guarantees permanent monitoring and is active during operation as well as during inactive moments without the user having to activate it.
In case of emergency, i.e. after failure of the load pressure brake and consequently exceeding the specified speed, the safety gear will automatically activate. It safely absorbs the load, preventing the creation of larger dynamic forces which could cause further damage.
Due to its design, the device remains in a safe state even in the event of an error (e.g. rusted ratchet pawl, broken springs or other influences such as basic corrosion or dirt).

EXCELLENT CORROSION PROTECTION

A housing optimized for outdoor applications (incl. water drainage holes on all sides) prevents a build up of water and the influence of moisture in extreme conditions (e.g. rain, fluctuations in temperature)
External components such as the chain guide and the stripper are zinc plated. Some of the internal moving parts such as the drive pinion, the ratchet pawl, the load chain wheel and the ratchet are MKS coated (Zinc flake coating).

PATENTED CRANK HANDLE

It guarantees the ideal power transmission for every application. Its folding lever-handle enables a working range of 360°, which increases productivity and reduces the risk of injury to the operator.

DIRECTION INDICATOR IN THE LEVER

A highly visible direction indicator located on the handle clearly shows the operating direction by means of arrow symbols.

EASY & SMOOTH FREE CHAINING

For quick take up and positioning of the slack chain – even with one hand. Designed not to accidently free chain while under load.

BUILT TO LAST

Even with intensive use, the YaleERGO 360® UT impresses with its lightweight aluminium housing and high-quality bearings.
The durable and high-quality powder coating of the surface offers additional protection in harsh environmental conditions.

EASY-TO-INSPECT SWIVEL HOOKS

Forged Hooks and cast safety latches provide for a positive and secure load engagement, as they can yield without breaking.
Bolt on hooks with nyloc nuts simplify the inspection process.

Options

CHAIN STOP & CHAIN CLAW*

Optionally, the devices can be equipped with our proven and tested YKST chain stop or the KKL chain claw.
With both options, the YaleERGO 360® UT does not need to be readjusted after the individual steps but is only required
in neutral mode.
*The usage is based on each country’s specific regulations.

SLIP CLUTCH (OVERLOAD DEVICE)

The slip clutch prevents damage to the unit, the handle rotates freely when hoist is overloaded. It reacts when the permissible load capacity is exceeded by 25 %.
Units with internal load limiter feature a black hand wheel for easy identification.
