HIGH TONNAGE CYLINDERS WITH SAFETY RING NUT, LOAD RETURN
These cylinders are particularly suitable for applications in which the load has to be supported for long periods. The lock nut can be screwed down onto the cylinder body to hold the load mechanically. This ensures that operation under load is absolutely safe. CGG cylinders have concentric grooves machined into the end of the rod to improve load grip, models above 30 tonne have lifting eyelets for ease of transport. From 50 tonnes upwards, the cylinders are plunging type and have device which prevents any over-stroke. The rod has a coloured zone which becomes visible 10 mm before the end of the piston stroke. All models can operate with off-centred load up to 8% of their nominal capacity.
