Section IIl. TECHNICAL PRINCIPLES OF OPERATION
1-13. MECHANICAL SYSTEM.
Tow Pole and Strut
Tow pole and strut provide a means to tow and steer the vehicle.
Mainframe provides a mounting place for the rest of the systems. It doubles as the
hydraulic fluid reservoir.
Brush frame holds the rotating brush. The brush is able to be raised and lowered and
moved from side to side. The brush frame also acts as a mount for the hydraulic
motor. The brush is reversible.
Engine is a two cylinder diesel that provides power for the hydraulic system.
Rear Axles and Brakes
Rear axles are mounted separately in the mainframe. The two hand brakes are
mounted on the mainframe and are manually operated mechanical brakes.
Transport and Safety Chains
Safety chains on the tow pole attach to the tow vehicle and transport chains on the
frame attach to the brush frame to stabilize the sweeper during transport.
