USE AND MAINTENANCE MANUAL FOR

JIB CRANE

GRL SERIES

The concept and construction:

•

The 360° rotating

jib cranes

of the GRL series are built based on the concept of modular

components which, assembled to each other based on commercial needs, as well as the standard

versions always available in the warehouse, they allow fast and economic creation of many

standardised and special configurations.

•

The base components, columns and arms, thanks to their extreme compactness can be assembled

together so as to guarantee the maximum use of the hook run and, thanks to their minimum lateral

encumbrance, allow the optimal use of the area where the jib crane operates.

•

The construction uses the most evolved technology based on high industrialisation production

processes and allows the creation of completely reliable and technically innovative machines

through economies of scale.

Arm electric rotation device:

Formed by a gear motor (fig. 8) fixed vertically in the upper part of the arm, made with a motor of epicycloid

type, with gears in a thermally treated oil bath and self-braking conical brake motor.

The pinion protruding from the gear motor is coupled with a toothed thrust bearing attached to the column.

Progressive starting and braking are ensured by a frequency variator (inverter).

Electric safety limit switch (fig. 9) on the rotation movements, installed, if necessary, to delineate the rotation

field of the arm of the crane.

Working on the auxiliary circuits at low voltage, it is a worm screw type with two thresholds of intervention

both in right rotation and left and also carries out the emergency function in safety if there is any fault or

malfunctioning of the first threshold of intervention.
