• OPERATION
When the descent button is pressed on the control
console, the compressed air from the regulator-lubricator
(not supplied) positioned at the inlet of the supply line (6)
is sent through the three-way valve (2) to the cylinder (1)
which releases the fall-proof safety hook. When the control
is released, the valve connects the air duct to the outlet,
permitting automatic insertion of the safety hook by means
of the return spring.
The regulator-lubricator unit is not supplied by the
manufacturer as it is an integral part of the bodyshop
compressed air supply system.
