STANDARD CYLINDERS OIL RETURN IN ALUMINIUM

force: 50-300t
stroke: 50-300mm
max working pressure: 700bar

Features

Solidly designed, the cylinder’s rod end has concentric grooves to improve load grip. Models above 30 tonne have lifting eyes and all models have anti-corrosive nitride treatment which makes them suitable to be used in harsh environments. A safety valve connected to the return chamber prevents any overpressure. The end of stroke nut has a wiper to prevent the entrance of dirt. They can operate with off-centred loads up to 8% of their nominal capacity. Given the sensitivity of the material to work stress we suggest a maximum use of 5000 work cycles.

OPERATIONAL AREAS

They are very solid cylinders recommended for pile testing operations and in situations in which the weight can be dangerous due to harsh conditions of adjustments or difficulties in transport. The oil return feature makes them suitable for synchronous lifting and lowering with SPLIT FLOW power packs.

OPTION:

– T  version, cylinder with integrated tilt saddle.
– F  version, cylinder with base mounting holes for fixing purposes.

 ACCESSORIES:

– ZTT tilt saddle reduces the effects of any possible off-centred load.

It’s important to drop the pressure inside the cylinder before disconnecting the quick coupler to avoid problems if re-inserting or  lowering the load. In case some pressure persists it is possible to use the apposite tool KTS38.
