WEEK/YEAR of manufacture

• Testing by “pick up”

– Protect the hydraulic circuit by a relief valve and a filter;
– 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:
– The cylinder rod must be greased before being
stored;
– Protect the cylinder shaft and trunnions during
high pressure steam cleaning.

• Spare parts: joint pockets, see price list.

• Instructions: on request.

• Guarantee: please refer to the general sales
conditions.

The normal operation of a CHAPEL telescopic
cylinder consists in the regular lifting of a tipper
body to progressively empty its load over its
path, whilst respecting the operating and safety
conditions.

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.

SAFETY PROCEDURES TIPPING
Plan a gap from 20 to 30mm

Ensure that:
– 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
(wet earth, etc…)
Strong adhesion to the body may cause the
vehicle to tip over.

THE FOLLOWING IS STRICTLY PROHIBITED:
– Do not 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.

«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.»
