What are the new functional uses of aerial work vehicles?

Aerial work vehicle, as the name suggests, is a special vehicle that can transport staff and equipment to the scene and carry out aerial work. This model has a wide range of uses, such as street lights, gardens, electricity, petrochemical, communications and other industries can be used. However, there are several ways of making the big arm of the aerial work truck, there are folding arm and hydraulic lifting, and the most popular one on the market is the telescopic arm type, and there is a hybrid arm type, and finally, the newly developed truck-mounted aerial work truck.

The folding arm type aerial work vehicle is also known as the curved arm type aerial work vehicle. The folding arm type lifting mechanism is folded by the multi-section box arm, which can be divided into upper folding and lower folding. The folding and unfolding of each arm are completed by the hydraulic cylinder between each section. It can complete the operation of a certain height and amplitude, and the lower fold can complete the space operation below the ground plane. This type of car is generally blue, the length of the big arm is generally about 13 meters, and the length of the big arm of the yellow card is generally about 18 to 22 meters, so the range of use is not much.

Hydraulic lifting aerial work vehicle, also known as shear fork aerial work vehicle, vertical lifting lifting mechanism according to the transmission mode can be divided into hydraulic transmission and mechanical transmission, according to its structural form can be divided into cross scissors and sleeve type. Cross scissors type according to the cross arrangement, hinged into a scissor-shaped connecting rod frame structure. When changing the Angle of the connecting rod crossing, the lifting movement is achieved. The change of the cross Angle of the connecting rod can be realized by the expansion of the piston rod of the hydraulic cylinder or the retracting and retracting of the wire rope. Sleeve type has truss type, box type or cylinder type, through the expansion of the multi-section sleeve to complete the lifting movement, the driving mode can be hydraulic transmission or wire rope pulley transmission. This vertical lifting mechanism has limited working height and small working range, but the working platform is large, and the support is stable, and is suitable for multiple people to work at the same time, which can make the high-altitude work more efficient and safer.

Telescopic boom type aerial work vehicle
The telescopic arm type aerial work vehicle is not the same, the telescopic arm type lifting mechanism is composed of a multi-section set, a telescopic box arm, including the basic arm and the telescopic arm, the telescopic arm can be one or more sections, each section is equipped with a hydraulic cylinder. When the hydraulic cylinder is working, each arm can slide up and down along the guide element under the push of the piston rod of the hydraulic cylinder, thus changing the length of the boom. The blue card aerial work vehicle can do 30 meters, and the yellow card can do 40 meters to 60 meters, so the work range is wider.

The hybrid arm type aerial work vehicle is a special model. The hybrid arm type lifting mechanism is composed of the folding arm and the telescopic arm, which combines the advantages of the two, expands the height and amplitude of the operation, and has a strong obstacle crossing ability. Because it is more complicated to produce, few users choose this model.

The big arm of the newly developed truck lifting aerial work truck is a straight arm telescopic arm type, the general blue brand is mostly, the big arm installation hoisting assembly can lift about 4 tons of items, the area of the platform plate is also large, can be used for transportation, the big arm can be about 20 meters, for aerial work, this truck lifting aerial work truck can be a multi-purpose car, the use is wider, It can not only work at altitude, but also be used as a crane.

Summary: Now on the market telescopic arm aerial work truck is the most popular model, folding arm, scissoring fork and mixed arm aerial work truck is now on the market demand has been very little, but the truck crane aerial work truck slowly occupies a certain share in the market.
