AJS / AJH - Aluminium 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 1kg 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.

Strokes from 75 to 305mm
Extremely low weight.
the 6.5 and 10 tonne jacks can be operated in any position (also upside down) and are equipped
with spring return piston and stop ring.
The 20 to 200 tonne jacks can be operated vertically or front face horizontally.
All jacksare provided with an overload protection valve.
From 20 tonnes capacity with additional mechanical stroke limiter.

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.

Applications
Yale hydraulic jacks are universally popular tools for use in workshops or on site for all kinds
of lifting and asembly 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 (305mm) are equipped with an elongated base plate.
