Truck-mounted cranes are increasingly accepted by people due to their advantages such as ease of use and flexibility. At present, the most common types of cranes on the market are telescopic boom truck-mounted cranes and folding boom truck-mounted cranes. What are the advantages and disadvantages of these two types of boom forms? How should we make a choice? For this reason, as a manufacturer of truck-mounted cranes, the editor will introduce the advantages and disadvantages of truck-mounted cranes to everyone.

1.The folding boom truck-mounted crane has a higher working efficiency

Due to the fact that the folding boom truck-mounted crane uses multiple hydraulic cylinders to form a boom connection mechanism similar to a joint, it can complete actions more quickly and efficiently
The efficiency of operation is also higher. However, the telescopic boom truck-mounted crane adopts a lifting mechanism for the retraction and release of steel wire ropes. When the drum rotates forward to retraction the rope, the hook rises; when it rotates backward to release the rope, the hook descends. Its working efficiency is relatively low.

2. The telescopic boom truck-mounted crane has a wider working radius
Under the same arm length, the telescopic arm truck-mounted crane can also expand the working depth by extending the steel wire hook, while the folding arm
Truck-mounted cranes are not easy to complete tasks with deep requirements.
3. Folding arms are more suitable for narrow working environments
This is determined by its structure. The folding boom truck-mounted crane is more suitable for relatively small working environments such as factories and warehouses, while the telescopic boom is
The space required for its structure is larger.
4. The telescopic arm is easier to control vertical take-off and landing
The telescopic boom adopts a lifting mechanism for the extension and retraction of steel wire ropes, which can strictly control the lifting and lowering of the lifted object, while the folding boom truck-mounted crane uses hydraulic pressure
It is very difficult to control the vertical lifting and lowering of the lifted object in the oil cylinder.
5. The folding arm can be equipped with various assistive devices
The folding arm truck-mounted crane adopts a hydraulic cylinder device to form a device similar to a articulated arm mechanical hand, which can be equipped with an empty working platform for operation
Buckets, jigs, hanging baskets, forks, various high grabs, screw drills, tire loading robots and pile pullers and other auxiliary tools. Because the front end of the telescopic arm is
Soft steel wire ropes are rarely seen with telescopic arms equipped with auxiliary devices.
6. The operation of the telescopic boom truck-mounted crane is relatively simple
The telescopic boom truck-mounted crane adopts a lifting mechanism with a drum for retracting and extending steel wires, which is relatively easy to operate. In contrast, the folding boom truck-mounted crane has multiple hydraulic cylinders.
It is rather difficult to perform actions similar to those of a mechanical hand.
7. The folding arm takes up less space in the entire vehicle
The space occupied by the folding boom is obvious at a glance. When transporting goods, the folding boom truck-mounted crane can retract the entire boom together, taking up relatively less space. In contrast, the telescopic boom truck-mounted crane can only place the boom horizontally, and thus occupies more space when the vehicle is in motion.
8. The telescopic arm is easier to install on the entire vehicle chassis
The telescopic boom has a relatively loose structure, which is conducive to the dispersion of the entire vehicle's load. Moreover, its center of gravity is also far from the installation position, especially during lifting
When carrying heavy loads, it is more conducive to distributing the axle load of the chassis.
For truck-mounted cranes with folding arms, whether they are mid-mounted or rear-mounted, due to their relatively concentrated structure, the center of gravity is prone to be concentrated on the chassis
On a certain axle, a relatively large load is often generated on a certain bridge, which is not conducive to the installation of the entire vehicle.
9. The price of folding arms is relatively higher than that of telescopic arms (straight arms)
The structure of the folding boom truck-mounted crane is relatively complex, and it also requires higher precision. The overall manufacturing cost is also relatively high. Telescopic boom
The structure is relatively simple, the manufacturing precision requirements are relatively low, and the overall cost is relatively low.
In conclusion, as the old saying goes, there is no best, only the most suitable. Folding boom truck-mounted cranes are suitable for small working Spaces such as warehouses and factories, and are also suitable for installing various auxiliary tools to carry out special operations. Telescopic boom truck-mounted cranes are more suitable for open working environments and can perform some simple vertical lifting, etc. The choice still depends on one's own working environment.
