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 arm frame is ineachBoth the location and the homework platform are safe for walkingThe walking speed decreases with the increase of lifting height.
3.Equipped with upper and lower control consoles(Ground control console and platform control console) and use directional switches to switch between the upper and lower control consoles. Lock the lower console when using the upper control.
4.The lower console indicates the temperature of diesel engine oil, 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.
9.When walking on the platform, if one wheel is empty, it can be driven solely by the other driving wheel through the distribution valve.
10.When the working arm angle is above the horizontal plane or the telescopic arm extendsWhen the distance is over 1.2 meters, there is a limit on 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 exceed1.5 °.
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.There areThe 24V auxiliary power unit can safely lower the working bucket to the ground when the engine or main oil pump fails.
16.Equipped with a torque limiter to control the operating range of the working bucket, limiting the extension and angle of the working arm when the operating range is reached, ensuring the stability of the entire vehicle.
17.The digital dual sensor detection circuit timely detects parameters such as length and angle, dynamically reflecting the working status of the boom. When one of the circuits fails, the other circuit can still complete parameter detection.
18.The work bucket has a weighing function, which accurately detects the platform load regardless of the position of the load on the platform. It should have two or more load capacities, and different load capacities allow for different operating ranges. When the platform load exceeds the allowable load capacity under the corresponding amplitude state, 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.
19.Equipped with automatic transmission, alarm, and cut-off functions: when the operating range reaches or exceeds the corresponding allowable rangeAt 80%,eachThe action speed will automatically decrease accompanied by a buzzer and flashing alarm, and the closer the amplitude is to the limit, the lower the working speed, and the more rapid the buzzer beeps. When the work amplitude reaches the allowable rangeAt 100%, the movement towards the dangerous direction will automatically stop.
20.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.
21.When the machine is parked on an uneven surface exceedingWhen the ground is at 5 °, the movement of the boom will be restricted.
22.When the equipment moves and rotates, it will emit sound and light alarms.
23.adoptPLC and CAN bus control methods simplify the circuit and facilitate maintenance and repair. Adopting metal air defense plug, the protection level reaches IP65.
24.The engine intake system adopts a closed two-stage filter, which is suitable for working in environments with high dust levelsAnd it is easy to maintain and upkeep.
25.Both the upper and lower control consoles should be protected by protective covers.
26.There are dust and sand prevention devices at the head of the boom, the piston rod of the oil cylinder, etc.
27.The hydraulic pump has automatic pressure compensation and load sensing functions, ensuring that the oil pump and engine are not damaged due to overload.
28.Equipped with an automatic shutdown device to prevent engine overheating and low hydraulic oil pressure.
29.Install a safety valve on the hydraulic circuit to prevent abnormal pressure rise in hydraulic components.
30.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.
31.Hydraulic and control components are imported brand products with high reliability.
32.The drag chain mechanism adopts sleeve type patented technology, with the sleeve made of surface treated aluminum alloy profile and the drag chain made of high-strength engineering plastic that is resistant to marine climate, suitable for harsh working environments.
33.There are lifting ring positions on the chassis and turntable for easy lifting.
34.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)
