Technical performance
1.1 Overall
It can adapt to specific operating environment, that is, it can work in humid, corrosive, dusty, high temperature and low temperature environment.
lThe machine has the function of automatic walking, which can walk fast and slow in different working conditions. Only one person can operate the machine to continuously complete lifting, advancing, retreating, steering, turning and other actions when working at high altitudes. Compared with traditional hydraulic The platform greatly improves work efficiency and reduces the number of operators and labor intensity.
1.2 Boom
There are dust-proof and sand-proof devices at the head of the boom and the piston rod of the oil cylinder.
lThe towline is a high-strength engineering plastic that is resistant to marine weather and adapts to harsh working environments.
1.3 Turntable
There are lifting rings on the bottom frame and turntable, which is convenient for hoisting.
The working bucket has an automatic leveling function, and the inclination angle of the working bucket relative to the horizontal plane cannot be greater than 1.5°.
1.4 Security Settings
There are upper and lower consoles (ground console and platform console) and the upper and lower consoles are converted by reversing switches. Lock function on the lower console when the upper control is in use.
The boom can be telescopic, luffed and slewed smoothly and has a buffer device.
The electric self-propelled crank arm aerial work platform adopts hydraulic brake and mechanical parking brake, which is easy to operate, safe and reliable, automatic compensation of service brake, and disc brake.
There is a foot switch on the platform, which can only be operated by stepping on the foot switch.
When the machine is parked on the ground with an unevenness exceeding 3°, the movement of the boom will be limited.
Each oil cylinder is equipped with a balance valve or hydraulic lock to ensure that the oil cylinder will not act automatically, and the connection between the oil cylinder and the balance valve and hydraulic lock is rigid.
1.5 Electrical system
Adopt PLC and CAN bus control mode to simplify the circuit and facilitate maintenance and repair. The metal air-proof plug is adopted, and the protection level reaches IP65.
The boom telescopic, luffing, slewing and platform walking are all controlled by electric hydraulic proportional control, which can realize stepless speed regulation.
When the device is in action, it will issue an audible and visual alarm.
The upper and lower consoles are equipped with emergency stop buttons, which can make the operator quickly turn off the power and prevent the platform from continuing to move when there is an unexpected situation in the operation.
The lower console has a fault indicator, and the upper console has a power meter.
The upper and lower consoles are protected by protective covers.
All actions are controlled by the operating handle on the workbench, the motor is infinitely variable speed, which effectively prolongs the service life of the battery and the motor, and the motor only consumes the energy during work. When the boom is in any position, the work platform can walk safely, and the walking speed decreases with the increase of the lifting height.
The machine is equipped with an intelligent charging system. It adopts a fully automatic charger, which can automatically complete the whole process of charging. After the battery is fully charged, it will automatically stop charging.
1.6 Hydraulic system
The main hydraulic components and control components are imported brand products with high reliability.
The hydraulic system has automatic pressure compensation and load sensing functions to ensure that the oil pump will not be damaged due to overload.
Equipped with a manual emergency lowering device, when the main oil pump fails, the working bucket can be safely lowered to the ground.
Install a safety valve on the hydraulic circuit to prevent abnormal pressure increase in hydraulic components.
The working bucket leveling adopts the static pressure leveling system. Compared with the traditional electro-hydraulic leveling system, the static pressure leveling system runs more smoothly and has higher reliability. More importantly, it can avoid malfunction caused by electrical faults.
