GTZZ12Curved arm aerial work platform

Main Configuration

Technical Features

1.Can adapt to the specific working environment of the shipyard, that is, can work in damp, highly corrosive, dusty, high temperature, and low temperature environments.

2. The boom is in various positions, and the work platform can walk safely; The walking speed decreases with the increase of lifting height.

3. There are upper and lower control consoles (ground control console and platform control console), and the upper and lower control consoles are switched using directional switches. Lock the lower console when using the upper control.

4. The lower console indicates the diesel engine oil temperature, oil pressure, water temperature, etc.

5. There is a device to prevent the engine from starting again when it is running.

6. The boom extends, changes amplitude, and rotates smoothly, and has a buffering device.

7. The telescopic, variable amplitude, slewing, and platform walking of the boom are all controlled by electronic hydraulic proportional control, which can achieve stepless speed regulation.

8. Reliable brakes should be installed for platform walking and arm rotation to ensure reliable control on slopes and during operation. Install manual rotation lock and release walking brake function to facilitate platform traction.

When walking on the platform, if one wheel is empty, the other active wheels can walk normally through the distribution valve.

When the angle of the working arm is above the horizontal plane, there is a limit to the walking speed of the vehicle.

11. The boom can perform multiple tasks simultaneously, including telescopic, variable amplitude, slewing, and platform walking.

12. The working bucket has an automatic leveling function, and the inclination angle of the working bucket relative to the horizontal plane cannot exceed 1.5 °.

13. Both the upper and lower control consoles are equipped with emergency stop buttons, which can quickly turn off the engine and prevent the platform from continuing to move in case of unexpected situations during operation.

14. The platform should be equipped with a foot switch, which can only be operated by pressing the foot switch.

15. Equipped with a 12V auxiliary power unit, it can safely lower the working bucket to the ground in case of engine or main oil pump failure.

16. Equipped with program action function, the tower arm telescopic arm can only extend when the tower arm reaches the maximum angle of amplitude; Only when the telescopic arm of the tower arm is fully retracted, can the tower arm swing downwards to prevent forward and backward tipping, ensuring the stability of the entire vehicle.

17. The work bucket has a weighing function to accurately detect the platform load, regardless of the position of the load on the platform. When the platform load exceeds the allowable load capacity, it should be able to display and alarm, and limit the platform's movement to ensure the strength of the working bucket and its connecting parts, as well as the safety of the work.

18. The engine throttle control should have three speeds. When there is no action for a long time, the engine will automatically reduce to low idle to meet energy-saving requirements.

When the machine is parked on a ground with an unevenness of more than 3 degrees, the arm movement will be restricted.

When the equipment moves and rotates, it will emit sound and light alarms.

21. Adopting PLC and CAN bus control methods to simplify the circuit and facilitate maintenance and repair. Adopting metal air defense plug, the protection level reaches IP65.

22. The engine intake system adopts a closed two-stage filter to adapt to working in environments with high dust levels; And it is easy to maintain and upkeep.

Both the upper and lower control consoles should be protected by protective covers.

24. There are dust and sand prevention devices at the head of the boom, the piston rod of the oil cylinder, etc.

25. The walking pump is a closed plunger electric proportional variable pump that can be infinitely variable in speed.

26. Equipped with an automatic shutdown device to prevent engine overheating and low hydraulic oil pressure.

27. Install a safety valve on the hydraulic circuit to prevent abnormal pressure rise in hydraulic components.

28. Each oil cylinder is equipped with a balance valve or hydraulic lock to ensure that the cylinder will not automatically operate, and the connection between the cylinder and the balance valve or hydraulic lock is rigid.

29. Hydraulic and control components are imported brand products with high reliability.

30. The drag chain mechanism adopts high-strength aluminum alloy drag chains to adapt to harsh working environments.

31. There are lifting ring positions on the chassis and turntable for easy lifting.

32. Clear identification and clear meaning.

warranty

1. Complete machine warranty for 12 months (excluding vulnerable parts)

2. Main structural components are covered by a 5-year warranty

3. Free initial maintenance of the engine and the entire machine (excluding consumables)
