5. INSTRUCTIONS OF INSTALLATION AT THE WORKING PLACE
The support for SECURPULLEY® must be a standard pipe for scaffolds, with external
diameter 48 mm.
The supporting pipe must be arranged horizontally; the supporting sleeve for
SECURPULLEY® must be positioned at the free extremity of the pipe, coupled to the
pipe and locked against the longitudinal movement.
N° 3 types of supports are foreseen for SECURPULLEY®, all of them made from a pipe
with diameter 48 mm:
a) piece of standard scaffolds pipe: connection to the vertical pipe by a scaffolds clamp
preferably of pressed type of thickness adequate to insure a good stiffness.
The sleeve for SECURPULLEYÆ is fixed at the extremity of the pipe and locked against
the longitudinal movements by two clamps, one per side of SECURPULLEYÆ
b) supporting pipe for SECURPULLEY® manufactured by TORNOMECCANICA:
includes a strong clamp for the connection to the scaffolding pipe, and a locking
system at one extremity, for quick locking and unlocking of SECURPULLEY® .
The connection of SECURPULLEY® by a cantilever pipe involves a bending stress in
the clamp and in the supporting pipes: with heavy loads in free fall, the braking efforts
can make such stresses become considerable.
Do not overcome the cantilever dimensions indicated by figure 2,
not to charge excessively the supports
Frequently check the tightening of the clamp screws

c) slewing support manufactured by TORNOMECCANICA.
The TORNOMECCANICA made slewing support, with quick slewing lock is a accessory
which includes the locking device for the SECURPULLEY? sleeve (see page9): it is made
from aluminium alloy, and therefore is particularly light.
The reinforced frame ensures a high rigidity under any load condition, and the
connection to the scaffolding pipe in N° 2 points eliminates the bending stresses on the
clamps and reduces quite a lot the efforts on them.
The slewing of the support allows to work at the working floor in an easier, qicker and safer
way, because the hanging loads can be rotated from/to the working floor together with the
whole support and SECURPULLEY®.
