Yale "PT" Heavy-Duty Lever Hoist

Capacities: from 800kg up to 6300kg

Information on the safe use of lever hoists

Hoist Features

• 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, making this hoist suitable for many industrial applications.

Optional Hoist Features:

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.

Slip clutch

Slip clutches fitted to Yale hoists reliably ensure that 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 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 hoist.

More Hoist Information

Yale Hand Lever Hoists - including the PT - are versatile, portable units for pulling, tensioning, lashing and lifting of loads. The operation of the Hand Lever hoists is easy and safe. Light weight, robust malleable cast iron model, free chaining, slip clutch, stamped steel- or aluminium housing, low operating effort - in the Yale product range you will always find an optimal hoist for every type of operation.

The brake system of all Yale hand lever hoists are based on the original Yale patent of the British engineer Thomas A. Weston dating back to 1875. All parts of the load brake re made of high quality materials and are protected against corrosion.

The engineering principle behind the load brake finds its rightful place in all hand lever hoists world wide. Yale exclusively uses asbestos free friction discs in all their hoists. The surface protected zinc plated alloy steel chains fulfil all the requirements of national and international standards and regulations. In accordance with safety regulations, the chain stops are designed to withstand double the rated capacity to ensure the chain does not unintentionally run free.

The drop forged load and suspension hooks that yield under overload instead of breaking, are made of high tensile steel and are standard for all Yale hoists. The hooks are fitted with robust safety latches and rotate 360°.

Every Yale ratchet lever hoist is factory tested with overload. The units are supplied with a test certificate showing the serial-No. Operating instructions which contain an EC declaration of conformity are also attached to each unit.
