1 It can adapt to the specific working environment of the shipyard, that is, it can work in humid, corrosive, dusty, high temperature and low temperature environment.
2 The boom is in any position, the working platform can walk safely; the walking speed decreases with the increase of the lifting height.
3 There are upper and lower consoles (ground console and platform console) and the upper and lower consoles are switched using the reversing switch. The upper control locks the lower console when in use.
4 The lower console indicates the diesel engine oil temperature, oil pressure, water temperature, etc.
5 It is equipped with a device that is restarted while the engine is running.
6 The boom is telescopic, variable amplitude and rotary, and has a buffer device.
7 The telescopic, variable amplitude, swivel and platform walking of the boom are controlled by electronic hydraulic proportional, which can realize stepless speed regulation.
8 Platform walking and boom rotation should be equipped with reliable brakes to ensure reliable control on the ramp and during operation. Install the manual swing lock and release the travel brake function so that the platform is towed.
9 When the platform is walking, if there is a round of emptying, the other driving wheels can walk normally through the distribution valve.
10 When the working arm angle is above the water level, there is a limit to the speed of the vehicle.
11 boom telescopic, variable amplitude, rotary and platform walking can work simultaneously.
The 12 work bucket has an automatic leveling function, and the tilt angle of the work bucket relative to the horizontal plane cannot be greater than 1.5°.
The 13 upper and lower consoles are equipped with an emergency stop button, which enables the operator to quickly extinguish the engine and prevent the platform from continuing to move when an unexpected operation occurs.
There should be a foot switch on the 14 platform, and only the foot switch can be operated.
The 15V has a 12V auxiliary power unit that can safely lower the work bucket to the ground when the engine or main oil pump fails.
16 has a program action function, the tower arm telescopic arm can only extend when the tower arm is swept to the maximum angle; only when the tower arm telescopic arm is fully retracted, the tower arm can be deflected downward to prevent forward tilting. And tilting backwards to ensure the stability of the vehicle.
The 17 work bucket has a weighing function that accurately detects 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 movement of the platform to ensure the strength of the work bucket and work bucket connection and the safety of work.
18 engine throttle control should have a three-speed speed. When there is no action for a long time, the engine automatically reduces to low idle speed to meet energy-saving requirements.
19 When the machine is parked on the ground with an unevenness of more than 3°, the boom movement will be limited.
20 When the device is walking and turning, an audible and visual alarm will sound.
21 PLC and CAN bus control mode is adopted to simplify the line and facilitate maintenance and repair. With metal air-proof plug, the degree of protection reaches IP65.
22 The engine air intake system adopts closed two-stage filtration to adapt to the dusty environment; and the maintenance is convenient.
23 upper and lower consoles should be protected by a protective cover.
There are dust and sand control devices on the head of the 24 boom and the piston rod of the cylinder.
25 The travel pump is a closed-piston electric proportional variable pump that can perform stepless speed regulation.
26 Automatic stop device to prevent engine overheating and hydraulic oil pressure from being too low.
27 Install a safety valve on the hydraulic circuit to prevent abnormal pressure rise in the hydraulic components.
28 Each cylinder is equipped with a balancing valve or a hydraulic lock to ensure that the cylinder does not automatically move, and the connection between the cylinder and the balancing valve and the hydraulic lock is rigid.
29 Hydraulic components and control components are imported brand products with high reliability.
30 The drag chain mechanism uses a high-strength aluminum alloy towline to adapt to the harsh working environment.
31 The bottom frame and the turntable are provided with a lifting ring for easy lifting.
32 logo is clear and clear.
1. Program action function: The tower arm telescopic arm can only extend when the tower arm is swept to the maximum angle; only when the tower arm telescopic arm is fully retracted, the tower arm can be deflected downward to prevent forward tilting and Tilt back to ensure the stability of the vehicle.
2. Weighing device of patented technology. Weighing device using the patented technology owned by the company, the weighing device can achieve accurate weighing of the workbench load. The weighing device is not affected by the position of the load on the platform, and avoids misjudgment and affects the normal operation of the platform.
3. PLC and CAN bus control. Install an industrial controller on the chassis, turntable and platform. These controllers have IP65 protection level and advanced CAN bus control. The circuit is simple and reliable. The maintenance and fault diagnosis are simple.
4, electronic leveling. The leveling of the working platform relies on the leveling controller to detect the angle of the platform relative to the vertical line, and the output signal controls the leveling proportional valve to achieve automatic leveling, high leveling precision and good reliability.
5. High security. Double spool hydraulic circuit prevents uncontrolled accidents caused by hydraulic valve stuck. The emergency power unit ensures that the car can be picked up in time even in the event of an engine failure.
6, anti-misoperation function. Prevent the engine from starting again, protect the starter and the flywheel ring gear; when the platform amplitude and height reach a certain level, the driving speed and the boom speed are automatically limited, even if the engine is at a high speed.
