cylinder type aerial work vehicle is a kind of multi-purpose aerial work machinery, its function is to send the platform carrying the operators and the equipment to the special engineering equipment at the designated height for aerial work. This equipment is widely used in high-altitude operations such as industrial and mining workshops, high halls, warehouses, stations, and squares. The whole machine is composed of a platform, a telescopic cylinder, a single-ladder or double-ladder anti-rotation mechanism, a chassis fuel tank, outriggers, walking wheels, etc. The platform has a telescopic cylinder to directly lift up. When the motor is started, the motor drives the gear pump to supply oil. The oil is fed into the cylinder through the one-way valve and electromagnetic channel. The telescopic cylinder rises section by section. When the platform rises to the maximum height, the system pressure is also The rated working pressure is reached. At this time, the oil spill valve is unloaded, and the oil pressure is kept at a constant working pressure. After the stop, the one-way valve maintains the pressure, and the platform stays at the maximum working position. The platform can be adjusted according to the working height of the site. Stay anywhere below the maximum height.
1. When the arm is lifted: first raise the small arm, extend the small arm, and then cross the lower arm and upper arm. When taking off and landing the boom, the maximum angle of elevation of the upper arm should not exceed 70 degrees, regardless of the angle of the lower arm. When working at height, it is strictly forbidden to fold the forearm.
2. When operating the boom, switch to (top-loading operation).
3. When operating the boom, first twist the action knob, then slowly pull the booster handle, and gently pull and release to achieve a stable action.
4. When landing: first lower the upper arm and lower arm, and finally close the lower arm.
5. When stretching the legs: first stretch the horizontal legs, and then extend the vertical legs; When closing the legs: first retract the vertical legs, then the horizontal legs.
6. The load of the working bucket is 200 kg, and overloading is strictly prohibited.
7. The lifting arm hook has a load limit of 1000KG and a safety value of 800KG, and must be operated directly behind the vehicle.
8. It is strictly forbidden to stand within the operating radius.
9. When encountering the restrictions of the working environment and the horizontal leg can only extend to one side, please work on one side after the horizontal leg is extended.
