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.
