CGR

CILINDERS, LOAD RETURN WITH SAFETY NUT – LOW PROFILE

force: 60-900t
stroke: 50mm
max working pressure: 700bar

Features

Pancake lock ring cylinders have a system which prevents any possible over-stroke. The rod on these cylinders has a coloured area which appears 10mm before the maximum stroke has been reached.  This version does not conform to ANSI B30.1.
These cylinders are particularly suitable for applications in which the load has to be left in a raised position for long periods. The threaded safety nut, which blocks mechanically the cylinder boby, allows to operate in total safety under the load.
All cylinders are supplied with integrated tilt saddle and eyelets in order to ease their transport .


OPERATIONAL AREAS

CGR cylinders are suggested in the construction and maintenance of bridges, viaducts, building and industrial sites  where the working space is limited. The protective nitriding treatment on these cylinders gives them excellent resistance to corrosion making them suitable for use in adverse environments.

STANDARD
– Integrated tilt saddle, reduces the effects of possible off-centred loads.

CGR cylinders have been designed for use in applications where space is limited and to stand the full load even without a pressure distribution plate below. It is anyhow recommended that pressure plates are placed both under the base and on top of the saddle to distribute the load if the support resistance is not compatible with the pressure shown in the chart. Non compliance with this notice could result in damage to the cylinder and/or the load being lifted.

Although the standard tilt saddle allows to adjust the working load, it’s suggested to avoid any side component especially if the cylinder is more than 20 mm of stroke.

During the lifting operation the operator must always be in a position to observe when the coloured end of section of the rod appears.

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 in order to lower the pressure in the couplers.
