The new generation of ratchet lever hoists model PT features improved techniques and ergonomical
styling. The advantages of the predecessor range have been maintained and further optimized.
The
proven stamped steel housing provides extremely low weight without limiting the reliability and sturdiness of the unit.
The free chaining device is standard,
low handle pull in spite of increased capacities as well as small hook-to-hook
dimensions are further outstanding features.
Optional
All models can be optionally equipped with an overload prevention device in the form of
a slip clutch which is factory preset to approx. 25 % ±15 %
overload.
The Yale
Ratchet Lever Hoist can be supplied with a height of lift to suit your requirements, please contact us for further details.

Slip
clutch
Slip clutches fitted to Yale lever hoists reliably ensure that lever hoists are not subject to overloads during operation.
When a pre-defined/adjustable overload value is reached the component
parts of the slip clutch, in accordance with engineering principle of the slip clutch, slide against each other and prevent a further overloading of the lever
hoist. When the slip clutch operates the load is still held secure by the independent load brake. Thus, the slip clutch provides double safety: firstly it
protects the operator from applying a mis-judged prohibited overload
and secondly it increases the working life of the lever hoist.
