Yale Aluminium hydraulic jacks

Capacities from 6,5 to 100 tonnes

Aluminium jacks combine light weight with high

lifting capacity. The use of high tensile aluminium

alloy allows lifting capacities of up to 100 tonnes

resulting in a very favourable 1,8 tonnes lifting

capacity per 1 kg weight ratio.

Operation of Yale hydraulic jacks is very simple.

Jacks are supplied ready for use, i.e. including

hydraulic oil, operating lever and, where applicable,

carrying handle and lifting claw.

Features

• strokes from 75 to 305 mm

• extremely low weight

• the 6,5 and 10 tonnes jacks can be operated in

any position (also upside down) and are equipped

with spring return piston and stop ring

• the 20 to 100 tonnes jacks can be operated

vertically or front face horizontally

• all jacks are provided with an overload protection

valve

• from 20 tonnes capacity with additional mechani-

cal stroke limiter

• all jacks with hardened alloy steel saddle and

sensitive lowering valve which is activated by the

operating lever

• all jacks from 20 tonnes provided with connection

port for pressure gauge or motor pump

Jacks with lifting claw

Jacks from 20 tonnes are available with a lifting

claw. In this case the jacks are provided with an

elongated base plate. The max. permissible working

load of the lifting claws is 40 % of the jack capacity.

Jacks with safety lock nut

Jacks from 20 tonnes can be supplied with a safety

lock nut. This device allows absolute safe jacking

over a long period. In this case the hydraulic jack

can operate like a mechanical support and the

hydraulic system can be totally released.

Application

Yale hydraulic jacks are universally popular tools

for use in workshops or on site for all kinds of lifting

and assembly applications, for construction,

ship building, power plants, general engineering,

metal fabrication and many more.

Applications are limitless.

Standard jacks with plain piston and jacks with

safety lock nuts cannot be used with a lifting claw.

To increase stability, all jacks with long stroke

(305 mm) are equipped with an

elongated base plate.
