The truck crane has the functions of lifting and transporting. After installing the auxiliary equipment, the function is more. It can hang trees, install billboards, hoist goods, etc. It is because the utility model is very practical, so it is very popular in the market. There are also many brands of cranes, such as Xugong, Changxing, Hercules, Xinfeigong, Balong and other cranes. If you want to buy a satisfactory truck crane, you must master certain professional knowledge. I will introduce the difference between the single pump and the double pump of the truck crane.
Firstly the structure is different
The oil pump is the power source of the truck crane. It can convert the force of the power take-off into hydraulic power. The double pump is equivalent to two single pumps. The conversion speed is faster, the power is blocked, and the hydraulic flow is more. Big, lifting is smoother.
Secondly, the configuration is different
The crane of the single pump is the basic arm, and the crane of the double pump is the extension arm. Generally, the basic arm of the single pump and the extension arm of the double pump are 1.5 meters apart; the flow rate of the single pump hydraulic system is 63L/min, the flow of the double pump hydraulic system is 100L/min; the volume of the single pump hydraulic tank is 160L, double The pump hydraulic tank has a volume of 260L.
Thirdly, the advantages of double pump
1. Stretching farther, the boom of the general double pump is 1.5 meters longer than the single pump boom, which can be lifted at a greater distance and has a wider operating range.
2. Save time, the operating valve of the double pump can operate the crane legs at the same time, which can save 20% operation time and improve work efficiency.
3. The speed is faster, the double pump crane has a large oil supply, smoother operation, faster lifting speed, saving time and saving 10% of the vehicle cost.
Fourthly, the advantages of single pump crane
1. The price is cheap, the crane under the same tonnage, the price of the single pump crane is about 10,000 yuan cheaper.
2. The maintenance cost is low, the system of the single pump is simpler and the maintenance is more convenient.
The above is the difference between a single pump and a double pump with a crane. The price of a single pump is relatively cheap, but for better performance, choose a double pump.
