NEW !! DGUV test certificate for overhead line construction !!

Benefits and 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).

The Yale ERGO360 UT Hand lever hoist with safety gear has been awarded the DGUV Test Certificate

Problem description
Failure of the load pressure brake on standard hoists

Cause
Defect of brake pads, pawls, brake threads or springs, heavily oily brake pads, extreme corrosion, dynamic and shock loads

Technical solution
Integrated safety gear which triggers at a defined fall speed! This provides complete intrinsic safety, as the mechanical system is constantly engaged and always puts the device into a safe operating state, even in the event of external influences such as corrosion, heavy soiling and wear!

Why we have chosen a certificate of the professional association (Berufsgenossenschaft)?
Our requirement was to obtain independent confirmation of the patented technical solution, as it goes beyond existing standards and significantly extends the safety requirement!

What is the added value for the user?
An independently confirmed higher effectiveness and safety of the user and the application! The importance of behavioral measures decreases and thus the effectiveness and safety increases, because the organizational solution is replaced by an effective technical one.
The so-called S-T-O-P principle!

What does the certificate cover?
All common work processes in overhead line construction

What may be made?
Lifting, lowering and tensioning

What is our certificate based on?
Extensive calculations and tests were carried out to obtain the certificate. Not only was the safe function of the safety gear tested, but the effect on the overall application (incl. various slings) was also taken into account. This is the only way to ensure the required safety of the device for the user, even in an emergency.

What happens to the device after the safety gear is activated?
The safety gear is always active. It reliably prevents the load from falling. Since the speed is limited, the dynamic forces are kept small and thus within the permissible range. After the safety gear has fallen in, the device can be unlocked and reset at any time so that the hazardous situation can be safeguarded!

This applies exclusively to the operating principle of the Yale ERGO360 UT!

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.
