Folding arm truck cranes suit small workspaces, equipment installation and special operations; straight arm ones are better for open environments.
The truck crane is more and more accepted by everyone because of its advantages of convenient use and flexibility, and it is used more and more in the south of China. At present, the most common on the market is the straight arm crane and the folding arm crane. What are the advantages and disadvantages of these two types of crane crane? How do we choose? The following is to introduce the advantages and disadvantages of these two types of truck crane.
● Folding arm crane working efficiency is higher because the folding arm crane adopts a plurality of hydraulic cylinders to form a similar joint arm connection mechanism, so that it can complete the action faster and work more efficiently. The straight arm truck crane uses a set of wire rope retracting lifting mechanism, the reel is turning to retracting rope, the hook is rising, and the reverse retracting rope hook is falling, its work efficiency is relatively low.
● The working radius of the straight arm crane is wider under the same arm length, the straight arm crane can also expand the depth of the work by placing a long wire hook, and the broken arm crane is not easy to complete the work requiring deeper.
● The folding arm is more suitable for narrow working environment, which is determined by its structure, the folding arm truck crane is more suitable for a relatively small working environment such as a factory warehouse, and the structure of the straight arm truck crane requires more space.
● The vertical arm is easier to control the vertical takeoff and landing. The vertical arm adopts the lifting mechanism of wire rope, which can strictly control the takeoff and landing of the crane, while the folding arm truck crane adopts the hydraulic cylinder, which is difficult to control the vertical takeoff and landing of the crane.
● Folding arm can be equipped with a variety of auxiliary equipment The folding arm crane adopts a hydraulic cylinder device to form a device similar to the articulated arm manipulator, and can be equipped with aerial work platform, work bucket, fixture, hanging basket, plate fork, a variety of grips, auger, tire loading manipulator and pile extractor and other auxiliary tools. Because the front end of the straight arm crane is a soft wire rope, few straight arms are equipped with auxiliary tools.
● The operation of telescopic straight arm crane is relatively simple. The hoisting mechanism of the straight arm crane adopts the lifting mechanism of the steel wire in the drum, and the operation is relatively simple, while the folding arm crane crane has multiple hydraulic cylinders, which complete the action similar to the manipulator, and is relatively difficult to operate.
● The folding arm occupies a smaller vehicle space at a glance, the folding arm can contract the entire lifting arm together when transporting goods, occupying a relatively smaller space, and the straight arm lifting arm can only be placed horizontally, and the vehicle occupies a larger space when driving.
● The telescopic straight arm is easier to install the vehicle chassis The telescopic straight arm is relatively loose in structure, which is conducive to the dispersion of the vehicle load, and the center of gravity is far away from the installation position, especially when lifting heavy objects, it is more conducive to the dispersion of the chassis shaft load. The use of folding arm crane, whether in the middle or rear, due to its structure is relatively concentrated, the center of gravity is easy to concentrate on a certain axis of the chassis, often a large load on a bridge, is not conducive to the installation of the vehicle.
● Folding arm price is higher than the straight arm crane structure is relatively complex, the accuracy is also higher, the manufacturing cost price is generally relatively high, the straight arm structure is relatively simple, the manufacturing accuracy requirements are also relatively low, the overall cost is relatively low.
After looking at the advantages and disadvantages of the above 9-point folding arm truck crane and straight arm truck crane, I believe you know whether to choose folding arm truck crane or straight arm truck crane, in short, it is still the old saying, there is no best, only the most suitable, folding arm truck crane is suitable for warehouse factories with small working space, and suitable for installing all kinds of auxiliary equipment, special operations, Straight arm truck crane is more suitable for open working environment, some simple vertical lifting, etc., which choice must be based on their own working environment.
