This wrecker has the functions of lifting, pulling, lifting, etc. It is convenient, quick, good-looking, safe and reliable. This truck wrecker is widely used in highways, public security traffic police, airports, terminals, auto repair industry and highway companies, etc.
Wrecker truck equipped with lifting winch device and wheel bracket which can lift, towing, back load and transport.Widely used in road, police traffic, airports, docks, auto repair company, industry and highway departments, timely, fast clean-up accident, failure, illegal and other vehicles.
Road wrecker is used for safety salvage of vehicles subject to city road, suburb way, highway, airport and bridge road. It is suitable for medium and small-sized cargos, cars and other special vehicles, which are allowed within the technical parameters of this kind
The tow wrecker is called the road wrecker, also known as road rescue vehicle. It has many functions such as lifting, pulling and lifting traction.
The INT series is out integrated line of tow trucks commonly called wreckers. We have a wide range of products with 6 different models ranging for the small 3 ton to the massive 60 ton with a 3 stage boom.
Many users of high-altitude operation trucks often encounter failures that the lifting platform cannot rise. So what should we do in this situation? Let's analyze the reasons for everyone on CLVEHICLES.COM below!
The hydraulic system is the main factor that causes the aerial work platform to not rise, the situation is as follows:
1. The hydraulic circuit is blocked.
The failure of the hydraulic circuit means that the hydraulic pipeline is blocked and the hydraulic oil cannot reach the hydraulic cylinder. The blockage of the hydraulic circuit is mainly in the various valves of the hydraulic system (one-way stop valve, reversing valve, regulating valve, etc.). The reasons for the blockage of the valve are: the hydraulic oil is dirty, and there are solid particles in the hydraulic oil, which causes the valve to jam or block ; The valve cannot be opened due to mechanical reasons, and the valve is blocked; the solenoid valve or the electrical part of the regulating valve causes the valve to fail to open.
2. The pressure of the hydraulic system is too low, causing the hydraulic lifting platform to be unable to lift.
The main reasons for the low pressure of the hydraulic system are: the overflow valve is damaged or the set value is too low, especially after the set value of the overflow valve is adjusted for overhaul, due to improper adjustment, it is easy to cause the set value of the overflow valve to be too small. If the system pressure is too low and the overflow valve is damaged, it will also cause the system pressure to be too low; serious hydraulic system leakage will also cause the hydraulic system pressure to be too low, such as serious oil leakage in the hydraulic pipeline or serious oil leakage in the cylinder, it will also cause the hydraulic system The pressure is too low, the aerial work lifting platform cannot rise with load.
