Taking Out Of Operation And Storage - Tractel tirfor TU Série Manuel D'installation Et D'entretien

matic self-clamping of the two jaws on the wire
rope, with the load equally distributed and held
continuously.
The movements of the forward and reverse
levers are double acting, with the load moving
each time the lever is moved in either direction.
6.2. blocstop™ safety devices:
Once the blocstop™ safety devices have been
installed they require no action by the operator.
They operate automatically during lifting and
lowering operations.
WARNING: During lifting operations, always
ensure that the secondary rope is sliding
freely through the device. If it is not, the
jaws must be opened. Tensioning the
suspension rope automatically opens the
jaws. If they do not open automatically,
change the blocstop™, replacing it with an
equivalent device which operates correctly,
and return the faulty device to TRACTEL S.A.S.
for servicing and repair, or send it to an
approved repairer.
WARNING: During lowering operations, an
immediate check must be carried out to
ensure that the secondary rope slides freely
through the device. If it does not, a lifting
movement must be performed until the
suspension rope is tensioned, thus opening
the jaws
WARNING : Operation of the lever on the
blocstop™ other than by the suspension
rope is forbidden.
WARNING : Keeping the lever on the
blocstop™ in the "open jaws" position, by
any means whatever, is forbidden.
