The full name of aトラック搭載クレーンisトラック搭載クレーンtransporter. This remarkable piece of equipment offers two essential functions: lifting and transportation. さらに, by adding auxiliary tools, it can expand its capabilities even further, enabling tasks such as lifting trees, installing billboards, and handling various goods. It is precisely because of its high practicality that トラック搭載クレーンs have gained significant popularity in the market. Undoubtedly, the crane component of aトラック搭載クレーンis of utmost importance. There are numerous crane brands available, with models from XCMG, Changxing, Hercules, Xinfegong, Shimei, and others being used more frequently. To purchase a satisfactoryトラック搭載クレーン, one must possess a certain level of professional knowledge. 今日, let’s delve into the differences between a single pump and a double pump for aトラック搭載クレーン.
私. Different structures
The oil pump serves as the power source for the crane of a トラック搭載クレーン. It plays a crucial role in converting the force from the power take-off into hydraulic power. あ トラック搭載クレーンwith a double pump is essentially composed of two single pumps working in tandem. This configuration offers several advantages. まず最初に, the conversion speed is faster. With two pumps collaborating, the hydraulic power generation is more efficient and rapid, enabling quicker response times for the crane’s operations. さらに, the power flow is unobstructed. The dual pumps ensure a continuous and smooth supply of hydraulic power, reducing the likelihood of power interruptions or fluctuations. This leads to a larger hydraulic flow, which in turn results in smoother lifting operations. When lifting heavy loads or performing delicate maneuvers, the increased hydraulic flow provided by the double pump system allows for more precise control and stability.
例えば, 想像してみてください トラック搭載クレーンat a construction site. With a single pump, the operator might notice some hesitation or jerkiness in the lifting process, especially when handling heavy objects. しかし, with a double pump, the lifting is seamless and fluid, providing a more professional and reliable performance. The enhanced power and smoothness not only improve the efficiency of the operation but also reduce the stress on the mechanical components, prolonging the lifespan of the crane.
Ⅱ. Different configurations
The cranes matched with a single pump and a double pump also have distinct configurations. The crane matched with a single pump is typically equipped with a basic boom. This boom is designed to handle standard lifting tasks and is suitable for applications where the reach and lifting capacity requirements are not extremely demanding. On the other hand, the crane matched with a double pump is usually fitted with an extended boom. 一般的に, there is a significant difference of 1.5 meters between the basic boom of a single pump and the extended boom of a double pump. This additional length provides greater reach and flexibility, allowing the crane to access areas that would be otherwise difficult to reach with a shorter boom.
In terms of technical specifications, the hydraulic system flow of a single pump is 63L/min, while the hydraulic system flow of a double pump is 100L/min. The higher flow rate of the double pump system enables faster movement of hydraulic fluid, resulting in quicker lifting and lowering speeds. This is particularly beneficial in time-sensitive operations where speed is of the essence. さらに, the hydraulic oil tank volume also differs. The hydraulic oil tank volume of a single pump is 160L, whereas the hydraulic oil tank volume of a double pump is 260L. The larger oil tank of the double pump system provides a greater reserve of hydraulic fluid, ensuring continuous operation even during extended periods of heavy use. This reduces the frequency of refilling and minimizes downtime, enhancing the overall productivity of the crane.
III. Advantages of double pumps
It can reach farther: One of the most notable advantages of a double pump crane is its increased reach. 一般的に, the boom of a double pump crane is 1.5 meters longer than that of a single pump crane. This extended reach allows for lifting operations at a greater distance, expanding the crane’s operating range. Whether it’s reaching over obstacles or accessing hard-to-reach areas, the longer boom gives the operator more flexibility and versatility. 例えば, in construction projects where tall buildings or large structures need to be serviced, the extra reach of a double pump crane can be a game-changer. It enables the crane to lift materials and equipment to higher levels without the need for additional equipment or complex setups.
Save time: The operating valve of a double pump can operate the crane outriggers simultaneously. This feature saves approximately 20% of the operating time compared to a single pump crane. When setting up the crane for a lifting operation, the ability to extend the outriggers quickly and efficiently is crucial. With a double pump system, the operator can deploy the outriggers simultaneously while preparing other aspects of the operation, reducing the overall setup time. This not only improves work efficiency but also allows for more tasks to be completed in a shorter period, increasing productivity and reducing labor costs.
Faster speed: The double pump crane has a larger oil supply, which results in smoother operation and a faster lifting speed. As mentioned earlier, the increased hydraulic flow provided by the dual pumps enables quicker movement of the crane’s components. This not only saves time but also reduces the fatigue on the operator. With a faster lifting speed, the crane can complete tasks more quickly, minimizing the waiting time between lifts and maximizing the utilization of the equipment. さらに, the faster speed can also lead to savings in vehicle usage cost. By reducing the time spent on each lifting operation, the crane can cover more ground and handle more loads in a given period, resulting in a more efficient use of resources and potentially saving up to 10% of vehicle usage cost.
IV. Advantages of single pump cranes:
Cheap price: For cranes of the same tonnage, the price of a single pump crane is approximately 10,000 yuan cheaper than that of a double pump crane. This price difference can be a significant consideration for budget-conscious buyers or those with limited financial resources. If the lifting requirements are relatively straightforward and the extended reach and higher performance of a double pump crane are not essential, a single pump crane can offer a cost-effective solution. It provides the basic lifting functionality at a lower price point, making it accessible to a wider range of users.
Low maintenance cost: The single pump system is generally simpler in design compared to the double pump system. This simplicity translates into more convenient maintenance. With fewer components and a less complex hydraulic system, the maintenance requirements are reduced. Repair and replacement of parts are often easier and less expensive. さらに, the lower hydraulic flow and pressure in a single pump crane result in less wear and tear on the mechanical components, further reducing the maintenance costs over the long term.
The above is a comprehensive overview of the difference between a single pump and a double pump for aトラック搭載クレーン. The price of a トラック搭載クレーンwith a single pump is relatively cheaper, making it an attractive option for those on a tight budget or with less demanding lifting needs. しかし, if better performance, increased reach, and faster operation are priorities, then a トラック搭載クレーンwith a double pump would be the preferred choice. Ultimately, the decision depends on the specific requirements of the user and the nature of the tasks to be performed. By understanding the differences between these two options, buyers can make an informed decision and select theトラック搭載クレーンthat best suits their needs.
