Aerial work truck is composed of automobile chassis, force extractor, hydraulic cylinder, telescopic leg, folding arm, central rotary mechanism, electronic control operating system, rotary bucket, hook, etc., there are 12 to 24 meters of different height types of aerial work truck, can be equipped with remote electronic control remote control. With safety, efficiency, intelligence and environmental protection and other significant characteristics, in the domestic mature market has been widely used in various industries including municipal, electric power, urban transportation, highways, Bridges, railways, shipbuilding, communications, architecture, landscape, advertising, airports, ports, stations, television broadcasting and so on.
Folding Arm
aerial work vehicle Chassis part: The well-known Chinese brand, heavy truck Ho chassis, single cab, wheelbase 2800mm, Isuzu 116hp, 6-speed transmission, power steering, air brake, 7.00R16 14PR vacuum tires, front axle 2 tons, rear axle 3.5 tons, special export chassis for aerial work vehicles.
Product characteristics
(1) The working arm of the aerial work vehicle is three-section folding, and the working area is large, which can adapt to different working conditions.
(2) The transmission adopts full hydraulic transmission, and the bucket and the turntable each have a set of operating systems to achieve the upper and lower dual position operation, and the turntable operation is preferred to the bucket operation.
(3) The vehicle is equipped with 1 ton auxiliary hook for lifting, and the maximum load of the working bucket can reach 200kg.
(4) Can be installed power unit, that is, when the main car fails, this power unit can be used for emergency, and it can also realize the extension of the arm, the extension of the leg, and the operation is flexible.
(5) Four hydraulic legs are respectively installed two-way hydraulic locks. Its function is to ensure that the leg will not shrink by itself after being put down; Prevent the "soft leg" phenomenon caused by leakage failure of hydraulic or pneumatic pipeline when the leg is working, so that the leg loses its function, resulting in serious accidents. The leg control valve is manual and the four legs can be controlled separately.
(6) The vehicle hydraulic 360 degree full rotation, control switch for electronic control.
1, pull the brake handle of the car, shift the gear lever in the neutral position, so that the engine idling, step down the clutch, pull the accelerator rod installed on the left side of the cab, hang the gear of the force taking device, so that the oil pump work, observe whether the oil pump has abnormal noise, vibration, oil leakage and other phenomena, in the winter cold, should idling for more than 10 minutes.
2, according to the exit combination control valve indication sign as shown on the left, first operate the leg.
3. Get on the car. Can be operated in two positions.
(1) Operation on the platform of the auxiliary vehicle.
After confirming that the exit operation is complete, push the "through the upper arm" handle of the exit control valve to the direction of the arrow, and then the boarding operation can be carried out. The personnel corresponding to the board operation sign as shown in the left picture, the "main arm", hit the "up" position can make the main arm rise, hit the "down" position, that is, the main arm return. The "middle arm" and "lower arm" are the same. The "lift" and "pull" of the "lifting arm" control the lifting and pulling back of the telescopic arm. The "lift" and "fall" of the "hook" are the telescopic arms connected with the main arm to lift and fall together. The "left" and "right" of the "rotation" are to make the upper part, that is, the arm and the connected working bucket, rotate left to right with the working platform.
The corresponding board operation sign is shown on the left. The corresponding action principle is the same as above. Only when operating on the sling, it is necessary to move the sling control transfer valve upward. During the operation process, the distribution handle of the exit leg operating valve must always be pushed to the "through the upper arm", and the distribution handle of the rotary operating valve must always be pushed to the "bucket", otherwise the operator on the bucket cannot move the working car.
Warning: When working at altitude, raise the lower arm first, and then raise the lower arm again. When the middle arm rises to about 2 meters, the main arm will start again. Do not fold the forearm when working.
4. After the completion of the operation, the working devices should be returned to their original positions, and then the control valve of the vehicle should be operated, and the vertical leg should be recovered first and then the horizontal leg should be recovered.
5, take off the power box gear, so that the oil pump stop working, release the brake device, the working car can change gear driving.
6, lifting operation:
The operator can use the end of the lower arm of the boom to lift various materials. When lifting, the weight of the goods should be known and compared with the rated load, when lifting the goods, it should first be lifted to the appropriate position, and then use the amplitude of the lower arm to achieve the position. At this time, the cargo should not exceed the maximum rated load allowed by the lower arm at this Angle.
Aerial work truck precautions
1, leg operation, you must first extend the horizontal leg, and then extend the vertical leg. When finished, you must first shrink the vertical leg, then shrink the horizontal leg.
2, first operation off, and then operation on the car. When you're done, pick it up, pick it up, pick it up.
3. When the boom works, lift the lower arm first and then move the upper and lower arms.
4, the staff into the work bucket, must fasten the safety belt, not overload.
5, the ground command personnel shall not leave the operation site.
