The brake system is an important component of the safety of the machine. It is essential to
carry out functional tests periodically (every 6 month).
First test : High speed :
• This test must be completed on flat ground or on ground that has a incline(less than that for which the
machine is rated. Refer to the manufacturers ID plate on the machine to determine the maximum
incline).
• Draw a line on the ground to create a stopping reference.
• Drive forward until the maximum speed is reached (Between 3 km/h (1,9 mph) or 6 km/h (3,7 mph)
depending on the machine being tested(Check the specification in the Operation Manual)).
• Release the joystick when the front wheels make contact with the stopping line previously drawn.
• When the machine comes to a stop, measure the distance between the middle of the front wheels and
the reference mark on the ground :
• If the distance is between 0,2 m(0 ft8 in) and 1,5 m(4 ft11 in), the test validates correct operation.
• Otherwise, contact HAULOTTE Services® to repair the system.
Second test : On ramp :
• On non slipping loading ramp (maximum slope 20 %).
• Draw a line on the slope to create a stopping reference.
• Climb on the ramp at microspeed.
• Release the joystick when the front wheels make contact with the stopping line previously drawn.
• When the machine comes to a stop, measure the distance between the middle of the front wheels and
the reference mark on the ground :
• If the distance is lower than 0,5 m(1 ft8 in) : the test validates correct operation.
• If the machine goes down again (skids, slips) of a distance higher than 0,5 m(1 ft8 in) :
Contact HAULOTTE Services® to repair the system.
For safety reasons, rensure that the following precautions are taken prior to testing commencing :
• Set up barriers to define the test area.
• Place the machine in transport position(Jib in horizontal position accepted)
• Wearing of a safety harness is essential.
