Yale AJH & AJS Aluminum Hydraulic Jacks

Yale AJHAJS Aluminium hydraulic jacks Picture

Load Capacity 6.5 - 100 t
Aluminium jacks combine light weight with high lifting capacity. The use of high tensile aluminium alloy allows lifting capacities of up to 100 tons resulting in a very favourable 1.8 tons 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 & Benefits

Aluminium Jacks with Lifting Claw
Jacks from 20 tons 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.
Aluminium Jacks with Safety Lock Nut
Jacks from 20 tons 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 be operated like a mechanical support and the hydraulic system can be totally released.
Stroke Lengths
From 75 - 305 mm.
Superior Portability
Extremely low weight.
Omnidirectional Operation
The 6.5 and 10 ton jacks can be operated in any position (including upside down).
Spring Return Piston and Stop Ring on the 6.5 and 10 Tons Jacks.
The spring return provides automatic, fast piston retraction, while the stop ring prevents dangerous over-stroke
Superior Versatility
The 20 to 100 tons jacks can be operated vertically or with front face in horizontal position.
Enhanced Safety with an Overload Valve
All jacks are provided with an overload protection valve.
Mechanical Stroke Limiter (From 20 ton Capacity Jacks).
The mechanical stroke limiter provides a lightweight, highly portable solution that prevents piston over-travel, ensuring safe, high-capacity, and rapid lifting in rugged environments like oilfields.
Hardened Alloy Steel Saddle
All jacks are equipped with a hardened alloy steel saddle (the part that contacts the vehicle) resists wear and deformation from heavy, concentrated loads, addressing the weakness of soft aluminum under high pressure.
Sensitive Lowering Valve Activated by the Operating Lever
The valve allows for precise, micro-adjustments in lowering speed, which is crucial when positioning a load.
Typical Applications
Hydraulic jacks are universally popular tools for use in workshops or on site for all kinds of lifting and assembly applications, for construction, shipbuilding, power plants, general engineering, metal fabrication and many more. Applications are unlimited. 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.
