5 6 7 8 Tons Truck Mounted Crane With Max Speed 90 Km/H 4*2 Telescopic Boom Truck Mounted Crane

Analysis of carrying capacity and performance of Dongfeng 4*2 crane
The following is the common situation of Dongfeng 4*2 on-board crane in terms of carrying capacity and crane performance (specific parameters will vary due to different models and crane brands) :

1. What is the maximum lifting weight?
Maximum lifting weight:
It is usually 3 to 8 tons, depending on the type and configuration of the crane.
For example:
Small cranes (e.g. 3.2 ton class) : The maximum lifting weight is about 3.2 tons.
Medium crane (such as 5 tons, 6.3 tons) : the maximum lifting weight is 5 tons or 6.3 tons.
Heavy crane (e.g. 8 tons) : The maximum lifting weight can reach 8 tons.
Note:
The maximum lifting weight is usually measured when the boom is fully contracted and the lifting point is close to the vehicle, and the actual lifting weight will be reduced after the boom is extended.
2. What is the length and working radius of the boom?
Boom length:

The boom is a multi-section retractable design, usually with 4 to 6 booms.
The full length is generally between 8 and 15 meters:
3.2 tons crane: the full extension length of the boom is about 8-10 meters.
6.3 tons crane: the full extension length of the boom is about 12-14 meters.
8 tons crane: the full length of the boom can reach 15 meters.
Working radius:

The working radius is the horizontal distance of the lifting arm from the lifting center to the lifting point, which is affected by the length of the lifting arm.
Specific data:
3.2 tons crane: the maximum working radius is 7-8 meters.
6.3 tons crane: the maximum working radius is about 11 meters.
8 tons crane: the maximum working radius is about 13-14 meters.
3. How is the stability of lifting operation?
Stability guarantee measures:

Hydraulic leg:

Dongfeng 4*2 crane is generally equipped with hydraulic legs on both sides, which can effectively enhance the stability of the vehicle after the legs are expanded.
High-end models may be equipped with rear legs to further enhance lifting stability.
Subframe:

The truck crane is usually equipped with a reinforced subframe, so that the chassis can withstand the torque and load during the lifting operation.
Center of gravity layout:

The crane is installed in the rear of the cab, and the center of gravity of the vehicle is reasonably designed to ensure that the vehicle is not easy to roll over during hoisting.
Anti-overload protection:

The crane is equipped with an anti-overload system that can monitor the lifting weight in real time to prevent instability caused by overload.
Suggestions for use:

Make sure the legs are fully deployed and grounded smoothly.
Avoid slope lifting operations and ensure adequate ground bearing capacity.
Avoid use in extreme weather such as high winds.
Sum up
Dongfeng 4*2 crane with its excellent load capacity and crane performance, suitable for small and medium-sized cargo loading and unloading and transportation, especially in narrow conditions and flexible operation scenarios.
