Truck-mounted cranes not only have the function of lifting goods, but also can transport goods. One vehicle has multiple uses. Because of its advantages, it is becoming more and more popular in the special-purpose vehicle market. Most of the truck-mounted cranes are equipped with outriggers. If you want to buy a good truck-mounted crane, the choice of outriggers is also very important, especially the rear outriggers. Today I will teach you how to choose the rear outriggers of the truck-mounted crane.

First of all, we must have a sufficient understanding of the rear outriggers of the truck-mounted crane. The biggest role of the rear outriggers is to provide the rear support of the whole vehicle, transfer the load during the lifting process to the outriggers, and ensure the bottom of the crane during operation. Support strength to ensure safety and protect tires from pressure to cause danger, and increase the load-carrying capacity of the vehicle.

We also need to understand the classification of the rear outriggers of truck mounted cranes: The more common rear outriggers on the market are H-shaped outriggers. This type of outrigger is divided into fixed rear outriggers, single-cavity hydraulic rear outriggers, Double-cavity hydraulic rear outriggers, generally big brand cranes will be equipped with original rear outriggers, which are of good quality and superior performance.

1. Fixed rear outriggers: not only can be raised and lowered vertically, but also support and assist when lifting

2. Single-chamber hydraulic rear outriggers: Single-chamber hydraulic rear outriggers can not only be raised and lowered vertically, but also can be extended on both sides, horizontally and vertically, and the support strength is better.

3. Dual-chamber hydraulic rear outrigger: This outrigger structure also includes left-right extension and vertical lifting. The extension width is larger than that of the single-chamber, and the support force is stronger. The extension width of the dual-chamber hydraulic outrigger is about 3.9 meters.

Installation position of rear outrigger: Generally, it is installed on the rear wheel chassis of the rear axle of the crane. During the hoisting operation, part of the load can be transferred to the outrigger, so as to ensure the supporting strength of the bottom and avoid Danger due to pressure on tires.

The rear outrigger can play a stabilizing and supporting role during the operation of the crane, ensuring the stability of the operation, reducing the load on the chassis beam, and ensuring that the vehicle will not overturn when the crane is being lifted. In actual operation, it must be Pay attention to the operation steps and maintenance of the outriggers, so as to extend the service life of the outriggers.
