Hydraulic crane for truck
The hydraulic grabble with crane is a mobile lifting equipment mounted on the chassis of the truck, which combines driving flexibility and lifting ability.
Basic structure
1. Truck chassis
It adopts a special or general truck chassis, which has the ability to drive on the road and has strong mobility.
2. Lifting mechanism
Booms: Common types include folding booms (truck-mounted cranes) and telescopic booms (hydraulically driven).
Turntable: Support 360° rotation to expand the working range.
Hydraulic system: control the boom telescopic, lifting and rotating.
Outriggers: Unfold during operation to enhance stability and prevent overturning
The logging crane is installed in the boxcar, the length of the hydraulic grapple is 7.0m with 2 sections extension. Generally speaking, we can advise you suitable model of forestry crane according to your truck length.
Characteristics
1. Flexible structure and power system
Hydraulically driven and multi-section telescopic boom design, it supports 360° rotation and load expansion and contraction, and accurately controls loading and unloading actions
High-strength materials increase the load capacity (up to 600 kg in one arm and up to 16 tons in high-end models).
2. Economy and compatibility: Adapt to trucks, truck-mounted cranes, agricultural loaders and other vehicles to reduce purchase costs
hydraulic crane and grapple mounted behind truck with H support, and the length of the arm is 7.8m.
There is windlass, which can lift or pull heavy objects, it usually consists of a horizontal cylinder, which is rotated by a motor to make the rope connected to the heavy object wound on the cylinder, so as to achieve the function of lifting or pulling the heavy object.
The core structure consists of the winch drum, power system (e.g. motor or hydraulics), drum and control system.
Purpose: Equipped with a movable pulley block to multiply the traction force and realize a single winch to drag heavy loads
Through power drive and mechanical structure innovation, the winch has become an indispensable tool for off-road and harsh environment operations. In addition, details such as LED remote control lighting at night are designed to enhance the suitability of harsh environments
The support is H type which is more suitable for truck due to its structure. So the height of chassis should be informed if you want to install the hydraulic grapple and crane.
The Foresty crane and hydraulic grapple is installed behind of the truck head as photo display. We advise H type support legs to match the truck, not only for height but its width. The support is extension-type and it can adjust the length accordingly.
