How to customize Isuzu truck

The Isuzu Cargo Crane Truck is a special vehicle that can be hoisted and transported, which is a combination of a top-mounted crane and a chassis truck. The crane part consists of a jib with several sections of boom, a turntable that can rotate 360°, and a chassis connected to the sub-beam, including an outrigger box, left and right horizontal and vertical outriggers, a lifting mechanism, hydraulic oil circuit, electrical control, etc. Partially composed. Various combined actions of the truck-mounted crane are realized through the actions of telescopic, slewing, lifting hook, luffing and other mechanisms, and lifting operations are realized through the combination of different actions. Isuzu Cargo Crane Truck can be divided into several structural forms. One is the traditional truck-mounted crane structure. The Isuzu stiff boom crane can lift heavy objects through the pitch of the big arm, and can also realize the vertical lifting of heavy objects by retracting and releasing the wire rope through the winch. The other type is the Isuzu knuckle arm crane. The Isuzu knuckle arm crane usually achieves lifting of heavy objects through the expansion of the arm body. The lifting action of the heavy object can be flexibly controlled by controlling the oil cylinder of each arm body. However, if you want to realize the lifting of heavy objects, Vertical lifting requires controlling the posture of each arm body at the same time, which is difficult to operate.

Comparison of the advantages and disadvantages of Isuzu folding arm crane and straight arm crane：

A. Structural features:

The structural characteristics of the Isuzu stiff boom crane are similar to those of the car crane. The telescopic arm part cannot be folded. Due to the limitations of its arm telescopic mechanism, there is only one luffing mechanism, which limits the straight arm crane's ability to operate in a small space. All movements of the knuckle-arm truck-mounted crane are fully hydraulically driven and have two luffing mechanisms. The telescopic arm has a load-retracting function and is flexible in operation. It is especially suitable for operations in small spaces, such as tunnels, shorter factories, etc. In the Pearl River Delta Economic Zone, the relocation and lifting business in factories is almost exclusively dominated by knuckle arm cranes.

B. Working principle:

The Isuzu stiff boom crane uses the rotation of the drum to drive the wire rope to lift objects and expand and contract the boom. However, all Isuzu knuckle boom crane use hydraulic drive to realize the telescopic and lifting of the boom. Relatively speaking, the working principle of the folding arm crane is more complicated, but its movement is more flexible. Whether it is lifting or moving objects, it takes less time than a straight arm crane.

C. Vehicle layout:

The straight arm crane is easier to install on the vehicle chassis. The straight arm crane structure is relatively loose, which is conducive to the distribution of the vehicle load. It is more conducive to dispersing the axle load of the chassis when lifting. When using a knuckle-arm crane, whether it is mid-mounted or rear-mounted, the structure is relatively concentrated when the knuckle-arm crane is fully retracted, and the center is easily concentrated on a certain axis of the chassis, which often causes overloading of a certain bridge, which is not conducive to the overall situation truck installation.

D. Working radius:

The working radius of the Isuzu stiff boom crane is much larger than that of the knuckle arm crane. This is because the lifting height of the straight arm crane is greater than that of the knuckle arm crane, so its working radius is also several times that of the knuckle arm crane. Therefore, straight arm cranes are more suitable for lifting operations outdoors and can lift higher and farther objects. The folding arm crane is more suitable for lifting goods in small spaces. The straight arm crane can extend the working depth by extending the wire rope, and is especially suitable for special working conditions such as deep wells. The folding arm is not easy to complete for deep working conditions.

E. Work scene:

The turning radius of the knuckle arm crane is small, the operation is flexible, the efficiency is high, it does not occupy the space of the carriage, and it is easy to load. In addition, the knuckle arm crane can be installed with various auxiliary tools, mainly installed on the head of the boom, such as work buckets and grab buckets. , aerial work platforms, various grabbers, clamps, hanging baskets, augers, plate forks, tire installation manipulators, pile pullers, etc., making the truck-mounted crane a multi-purpose machine, so the application scenarios of the knuckle boom crane are more diverse, which further expands the application scenarios of knuckle arm cranes. At present, it is widely used in busy places such as landscaping, farm woods, low-rise factory building handling equipment, ship ports, etc.

F. Operation difficulty:

The Isuzu straight-arm crane uses a hoisting mechanism with a reel to retract and unwind the wire rope. The operation is relatively simple and can strictly control the lifting and lowering of the hoisted object. The knuckle-arm crane is composed of multiple hydraulic cylinders, which are similar to the actions of a manipulator, so the operation is relatively simple. Complex and not easy to control. The manufacturing accuracy and manufacturing cost are higher than those of straight arm cranes.

G. Spare parts:

Isuzu straight arm cranes are now fully domestically produced, with lower prices for spare parts and short and guaranteed supply cycles. The core parts of the Isuzu knuckle arm crane are highly imported and have good micro-motion safety. The price of spare parts is high and the supply cycle is long.

H. Maintenance performance:

Since the telescopic cylinders of the Isuzu knuckle arm crane are all external, the cylinders are easy to disassemble and the maintenance cost of the Isuzu knuckle arm crane is lower. However, the telescopic mechanism of the straight arm crane adopts the form of built-in cylinder + pulley rope row, which makes maintenance difficult and costly. .

I. Economic performance:

Since the structure of the knuckle arm crane is relatively complex and the number of cylinders is relatively large, the price of the knuckle arm crane with the same load is higher than that of the straight arm crane.
