Types of Rear Outriggers for Truck-Mounted Cranes

8/17/20242 min read

There are different types of rear outriggers for truck-mounted cranes.

1. Fixed Rear Outrigger: This outrigger can move up and down but does not move side to side. It helps with lifting.

2. Single-acting Hydraulic Telescopic Rear Outrigger: These outriggers can extend to the sides, providing better support.

3. Double-acting Hydraulic Telescopic Rear Outrigger: These extend sideways and up, offering more extension width and stronger support.

What is a Fixed Rear Outrigger?

A fixed rear outrigger is a simple, vertical design. It supports the crane during lifting, providing stability. They are usually installed on the back axle of the loader crane and often have an H-shaped design. Fixed outriggers are simple and easy to use, but not as flexible as other types.

Advantages:

Simple and easy to operate.
Low cost.
Suitable for small cranes and simple applications.

What is a Single-Acting Hydraulic Telescopic Rear Outrigger?

Single-acting hydraulic telescopic rear outriggers can extend horizontally, beyond the cargo box. This type of outrigger can also move up and down, providing more support. Single-acting hydraulic telescopic rear outriggers are useful for larger supports on uneven or soft ground. They distribute the load, reducing pressure on the ground and providing stable support during lifting.

Advantages:

Suitable for various working environments.
Provides excellent stability and support.
Operated hydraulically for ease and reliability.

What is a Double-Acting Hydraulic Telescopic Rear Outrigger?

Hydraulic telescopic outriggers extend horizontally and vertically. They can extend horizontally and vertically. This design makes double-acting hydraulic telescopic rear outriggers wider and stronger. They offer a broader support range than single-acting hydraulic telescopic rear outriggers, especially when maximum working radius rotation is required.

Advantages:

The large extension width distributes the load and reduces ground pressure.
Stable when lifting heavy loads or working in a larger area.
The double-acting design makes the system more reliable and durable.

What factors should be considered when selecting rear outriggers?

Job Site: Rear outriggers improve stability and safety on uneven or soft ground.
Lifting Requirements: If the weight is close to the crane's maximum, outriggers can provide support.
Special Situations: Rear outriggers are important for maximum working radius rotation.

Conclusion

Rear outriggers for truck-mounted cranes are important for safe and stable lifting. Knowing the different types of rear outriggers and what they do helps us choose the right products for the job and make sure we are safe.
