2 PRODUCT DESCRIPTION
2.1 Description
A family of automatic hydraulic traf fi c bollards is identi fi ed with the name ROCK. The cylinder is driven by a hydraulic unit positioned
inside the same. The bollard has a manual safety release device which, if activated, allows the cylinder to be lowered, thus leaving the
passage free in the case of emergencies and/or mains power failure.
The automatic lowering of the hydraulic unit, can only take place with the accessory solenoid valve (art. ROCK/EL not supplied) installed;
in this case, the type of release can be selected by operating directly on the solenoid valve and activate, or not, the automatic lowering
of the cylinder in the event of power failure.
The accompanying accessories are shown in the “PRODUCT ACCESSORIES” table (page I-9).
2.2 Content of the packaging
All the material is accurately controlled and inspected by the manufacturer before shipping.
On receipt of the bollard, make sure that it has not undergone damage during transport and that nothing has been tampered with or
removed. If damage or missing parts are detected, immediately inform the carrier and the manufacturer, and produce photographic
documentation. On receipt, during unpacking, dispose of the packaging components with reference to National Disposal Laws regarding
solid waste.
2.3 Lifting and Transport
Suitable equipment must be used to lift and transport the bollard, with respect to work place safety regulations in force in the area of
installation of the product.
The eye-bolts and the ropes must have capacity higher than the weight to be lifted, be in good working order and must have CE marking
and respective certi
fi cation in force.
WARNING For transport of the bollard, vehicles are requires with minimum capacity higher than the weight declared for the same (the
weight of the bollard is given on the identi fi cation plate). Before beginning handling, check the ef fi ciency of the lifting devices and
their capacity. During bollard lifting and handling operations, all possible precautions must be taken in order to prevent hazardous
movements, which could cause accidents or damage to the persons and/or materials and objects. Avoid sudden movements, which
could lead to damage to the bollard.
The bollard must be handled by expert personnel.
