2) Road sweeper trucks advanced features
This vehicle is a wet road sweeping vehicle retrofitted by adding a top mounted dedicated sweeping device powered by ISUZU technology auxiliary engine to the ISUZU chassis. This CEEC5070TSL road sweeper truck has a simple and proper structure with four brushes in the middle and a suction port at the back part of the vehicle. The efficient suction system makes low noises when the vehicle is working. The whole vehicle is stable in performance.
a. At the back part of this street cleaning truck there is an indicating arrow to make sure the road sweeper truck can work safely.
b. With individual controls for the water sprayed through the brush disks or the suction pipe, this vehicle is easy to operate.
c. High quality automatic centrifugal clutch is adopted in this product to start the auxiliary engine without load. The clutch is in a semi-open structure which makes it easy to check to what degree the wear plate is worn. Just unscrewing one gland bolt you can take out the core of the clutch to replace the wear plate.
d. The hydraulic valve group of our road sweeper truck is composed of thread cartridge valves introduced from the American HF (Hydra Force) company. The thread cartridge valves feature compact structure, light weight, powerful functions, high reliability and easy maintenance. They are popular hydraulic valves for vehicles in Europe and America. The hydraulic valve group contains an electric-hydraulic proportional speed regulating valve to control the revolving speed of the sweeping brushes. The operator can achieve stepless regulation to the revolving speed of the sweeping brushes by adjusting the electronic control rotary knob. Besides, customers can also choose to install the sandwich valve group produced by Japanese Yuken according to the practical need.
e. The driving motors of the sweeping brushes and the brush disks are high-quality cycloidal motors which have high transmission efficiency and long service life.
f. The electronic control system of this road sweeper truck is controlled by single chip microcomputer. The highly centralized control box is quite intelligent with low failure rate and only a few control switches. With such an electronic control system, the operator can control all the operations of the vehicle in the cab.
g. When dumping garbage, the garbage bin can incline 60° at most. Since the water tank is mounted under the garbage bin, the bottom board of the garbage bin has already inclined 12° from the vehicle body. This makes the garbage dumping more easily and thoroughly.
h. Various sorts of optional equipment are available. Customers can decide to install rolling brushes to the suction port. Rear mounted dirty water suction pipe or snow plow can be added to this road sweeper truck to make it multifunctional.
