HOW TO CHOOSE A TELESCOPIC CYLINDER?
Plan a gap from 20 to 30mm.
The necessary tipping pressure is less than the maximum recommended operating pressure
The load is compatible with the vehicle.
The ground is stable and flat.
There are no people or obstacles in the working perimeter (at ground level and high up).
The load has been distributed uniformly
The tyre pressure is correct.
The load is progressively emptied.
PAY ATTENTION to loads sticking in the body
Move the vehicle during tipping.
Rapid operation of the cylinder tipper control.
Working under a raised tipper body that has not been secured.
Tipping if the wind is buffeting the vehicle.
The study, the conception and the technical specifications are only suitable for tippers.
– Seamless tube NFA 49311/312 tube machined, ground, treated and polished Ra<0.4μ
- Round bar Steel C35R, machined, ground and polished Ra<0.4μ
- Each component is nitrited (except cylinder bottom)
– Rod: compact polyurethane lip seal + 1 polyurethane wiper seal
– Protect the hydraulic circuit by a relief valve and a filter.
– The cylinder rod must be greased before being stored.
– Joint pockets
The normal operation of a telescopic cylinder consists in the regular lifting of a tipper body to progressively empty its load over its path, while respecting the operating and safety conditions.
Safety procedures when tipping
Ensure that:
(wet earth, etc.). Strong adhesion to the body may cause the vehicle to tip over.
IT IS STRICTLY PROHIBITED:
«Not following the above safety procedures may cause considerable over-pressures and transverse forces that are not allowed by the cylinder. This may therefore cause considerable damage and place the operator in danger».

RECOMMENDATIONS
– Check the state of purity of the fluid (foreign bodies).
– Remember to purge the cylinders and the hydraulic circuit.
– Do not weld onto the cylinder.
– Do not, under any circumstances, use the tipping system as a mechanical stop.
– Never allow the body to lean against the cylinder when in stowed position (gap > 20mm).STORAGE
– Protect the cylinder shaft and trunnions during high pressure steam cleaning.SPARE PARTS
A tipping system is solely a lifting device, it cannot, under any circumstances, stabilise or guide the tipper body.
On choosing a cylinder, the weight C is equal to the weight of the body added to the weight of the load.
