In recent years, due to the increase in labor costs in China and the growing demand for operational efficiency, the truck-mounted crane industry has developed rapidly, with sales increasing year by year. Compared with truck cranes, the investment payback period of truck-mounted cranes is shorter. Under good business conditions, the cost can be recovered in about one year, and for users with poor business conditions, the cost can also be recovered in about two years. Therefore, the market demand for truck-mounted cranes is increasing day by day. Truck-mounted cranes can be classified into folding boom type and straight boom type based on the boom. So, what are the advantages and disadvantages of the folding boom type truck-mounted crane? The editor summarizes as follows:
I. Advantages
1. Higher efficiency
The folding boom truck-mounted crane is similar to the palm joint of a human body and can perfectly perform various movements, making it more flexible and efficient.
2. Low-rise factories are more useful
The folding boom truck-mounted crane can be folded twice and is more suitable for factories, warehouses and other relatively small or low working places.
3. Various assistive devices can be installed
The folding boom truck-mounted crane is similar to the arm of a robot. Various "palms" can be installed at the end of the arm, such as high-altitude baskets, grabs, clamps, pallet forks, breakers, auger drills and other types of mechanical hands.
4. It occupies less space in the cargo box
Due to its folding boom structure, the folding boom truck-mounted crane can be folded and placed. Thus, when the vehicle is in use, it can obtain a larger loading space and increase the utilization rate of the cargo box.
5. Convenient for maintenance
The telescopic hydraulic cylinder of the boom of the folding boom truck-mounted crane is installed outside the boom, making it easy to maintain when problems occur.
two Disadvantage
The hydraulic system pressure of the folding boom truck-mounted crane is higher than that of the straight boom truck-mounted crane
To reduce the pressure of the luffing cylinder, a connecting rod mechanism is often adopted. The oil pump used in the hydraulic system of the straight boom truck-mounted crane is a gear pump, while the oil pump used in the folding boom truck-mounted crane must be a high-pressure plunger pump.
2. Rotation Angle
The rotary movement of the folding boom truck-mounted crane is accomplished by the rack on the rotary hydraulic cylinder driving the gear bar at the lower end of the column to rotate. The rotation Angle is determined by the hydraulic cylinder. Therefore, the folding boom truck-mounted crane cannot rotate continuously. Under normal circumstances, the maximum rotation Angle of the folding boom truck-mounted crane is 360 degrees.
Folding boom truck-mounted cranes have both advantages and disadvantages. The boom form of truck-mounted cranes can be selected according to the working environment, and the prices of truck-mounted cranes with different booms also vary. The most important thing is to suit yourself.
