ROLLAND ROLLFORCE Instruction Manual page 22

Breaking circuit :
Spreaders come equipped with three braking systems, each of which ensures precise
operating.
When stationary, the hand brake should be used (manual). When moving, it's the hydraulic
or pneumatic brake which is used. The third system is a back-up systyem in the event of
trailer separation (cord between the hand brake and and a fixed point in the tractor).
Connect the security cord in the event of trailer separation; this activates the parking brake.
Check for good cable tension to the connecting rods at the outset of each journey.
Any trailer whose load bearing weight PTAC exceeds 1.5 tonnes is
automatically equipped with assisted braking. This can be connected to
the tractor's braking system.
Hydraulic braking circuit :
Install red hose (4) on the pressure outlet « BRAKES» on the tractor.
Ensure full functioning of the command box and the absence of leaks from the couplings.
Braking pressure : 100 to 130 bars.
