rulmeca 80LS Manual De Instalación Y Mantenimiento página 5

a) Transport/Handling:
For safety reasons during transport and assembly a lifting rope according to the max. weight of the
pulley has to be used. The weight of the pulley is stamped on the data plate and /or given in the
catalogue.
The rope has to be fixed on the shaft ends.
As to motorized pulley types 500H – 1000H/HD, a steel rope or chains should be fixed to the eyebolts,
which are located on the mounting brackets.
b) Motorized Pulley Mounting Orientation:
Before installing the motorized pulley, please ensure that the data plate information is correct to
your specification.
At any time, RULMECA motorized pulleys should always be mounted so that the pulley shafts are
1. Horizontal,
2. Parallel to idler rollers, and
3. Perpendicular to the conveyor belt centreline.
As to motorized pulley types 80LS to 500M "UP" is indicated with the word "UP" stamped on the
pulley shaft.
All motorized pulleys are to be mounted as shown on the sketch below.
This instruction does not apply to types TM 500H – 1000H/HD.
In case of a non-horizontal installation, of more than +/-5 degree, please consult RULMECA.
For motorized pulley types 500H – 1000H/HD please ensure that
Motorized Pulley's are positioned in such a way that the mounting brackets are located horizontal or vertical
to the conveyor frame. The cable entry of the terminal box should be located downwards or in a 90° position.
At any time all Rulmeca Motorized Pulleys shown in this catalogue must
be fitted with a conveyor belt to prevent overheating.
Motorized pulleys fitted without a belt must be referred to RULMECA.
Installation and mounting of the motorized pulley in another position as described could cause
severe product damage and voids product warranty.
c) Mounting Bracket:
As listed in the catalogue, use the correct RULMECA mounting brackets matching the respective types of
motorized pulleys.
Note that it is physically possible, but not permissible, to interchange mounting brackets between models.
Mounting brackets designed for smaller diameters or lower-powered pulleys may not be used for larger diameters or
higher-powered pulleys.
Mounting brackets must be mounted to frame in such a way that belt pull is resisted by the shoulder or base of the
mounting bracket. Motorized pulleys types 80LS to 500M have a top shaft retaining plate. This plate is not designed
to resist belt pull.
