LuchengWarehouBefore connecting the motor to the elevator, the elevator manufacturer should first make the motor shaft keyway perpendicular to the tightening bolt. To ensure uniform stress, first screw on the mounting bolts at any diagonal position, and then tighten the four mounting bolts one by one. After that, tighten the tightening bolts. All tightening bolts shall be fixed with a torque wrench according to the indicated fixed torque data, and the use of elevators and lifting platforms shall be checked
Goods should be stacked well on the platform, no one should stand around to watch.
Lucheng.In fact, it is also important to pay attention to some details, as follows: It is actually difficult to pierce the bearings into the shaft pins when excessively installing them. However sometimes, some people think of using a hammer to hammer the bearings to facilitate the installation, and use brute force during installation. In fact, directly striking the bearings with a hammer can cause significant damage to the bearings, which is the main reason for causing bearing damage and reducing the service life of the bearings. So when installing bearings, we must not go too far. Fortunately, we can place some soft cloth or cardboard on top of them before installing them.
The elevator is a kind of elevator equipment composed of a walking mechanism, a hydraulic mechanism, an electric mechanism, and a support mechanism. The hydraulic oil forms a certain pressure by a vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, flameproof electromagnetic directional valve, throttle valve, hydraulic control one-way valve,LuchengCustomized lifting cargo elevator, and balance valve. This allows the hydraulic cylinder to move upward and lift heavy objects. The return oil from the upper end of the hydraulic cylinder returns to the tank through the flameproof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. Observe the reading value of the pressure gauge on the pressure gauge.
.Incorrect connection of the elevator motor When a coil, coil group, or one phase winding group is connected inversely, it can cause a serious imbalance in the three-phase current and cause the winding to overheat.
It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.
Precautions for using guide rail type elevators: Overloading and transporting flammable and explosive products are strictly prohibited.
'Using the elevator is not about maintaining and overhauling the equipment after it has failed. It is important to maintain the equipment in accordance with the correct maintenance and overhaul. First, do the preparatory work to eliminate all possible fault problems and accidents. I hope that today's summary of knowledge points by the editor can help everyone.'.
The daily maintenance of guide rail type lifting equipment should pay attention to regular inspection and maintenance, eliminate hidden dangers, and eliminate faults. Doing so is beneficial to improving work efficiency extending the service life of the equipment, the clothes will repeatedly slap the car paint and ensuring the safety performance of the elevator.
It is good for aerial work vehicles not to cover their clothes and park outside. If it is windy and rainy, especially if the vehicle blows sand on the clothes, causing many fine scratches on them, as the paint will become black over time. In addition, when the wind does not directly spray powder or clean the mechanism on the sand, it should be washed with water, and prevent the vacuum cleaner of the aerial work vehicle from scratching the sand particles on the paint surface.
middleman.Before connecting the motor to the elevator, first screw on the mounting bolts at any diagonal position, but do not tighten them. Then screw on the other two mounting bolts at diagonal positions, and then tighten the four mounting bolts one by one. After that, tighten the tightening bolts. All tightening bolts shall be fixed with a torque wrench according to the indicated fixed torque data, and the use of elevators and lifting platforms shall be checked

Hydraulic pump station: domestic lifting platform dedicated pump station, mesh type, and iron plate sealed type.
Executive standard.It is good for aerial work vehicles not to cover their clothes and park outside. If it is windy and rainy,LuchengFixed lifting cargo elevator, the clothes will repeatedly slap the car paint especially if the vehicle blows sand on the clothes, causing many fine scratches on them, as the paint will become black over time. In addition, when the wind does not directly spray powder or clean the mechanism on the sand, it should be washed with water, and prevent the vacuum cleaner of the aerial work vehicle from scratching the sand particles on the paint surface.
Drain and discard the hydraulic oil from the hydraulic lifting cargo elevator. For the outdoor guide rail elevator, tighten the joint and remove the oil filter. After cleaning, clean it with compressed air, and then return it to the oil tank and connect the pipeline.
To ensure excellent power supply at the installation site, install a separate distribution box. When using the distribution box, the electrical leakage switch must meet the requirements for construction elevators. If the installed construction elevator is variable frequency, the selection of the leakage switch should be compatible with the frequency converter.
Lucheng.Secondly, there should be no dirt on the friction surface. If there is any dirt, it should be washed off with gasoline or thinner; The reduction gearbox, gearbox, external meshing gear, and other parts of the equipment, as well as the hydraulic oil, must be tested according to the requirements in the table; Correct maintenance of the hydraulic guide rail elevator: Regularly inspect the wire ropes at various parts for broken wires and looseness. If any such phenomenon is found, replace it in a timely manner. The maintenance of the wire ropes must be carried out in strict accordance with the specifications; Check the connection condition of each part according to the braking rules and regulations. If there is any looseness, whether there are noises and faults according to regulations, and promptly remove all faults; When installing, disassembling, and adjusting the rotating mechanism of the equipment, it is important to note that the reducer and the gear center line should be parallel, and the meshing clearance should be appropriate; Regularly conduct a comprehensive inspection of the equipment to see if there is any damage to the wires and cables, and if there is overheating of the motor. Replace the motor in a timely manner and eliminate the fault before continuing operation; Ensure that the bearings, boxes, distribution boxes, and brushes of the motor are kept clean,LuchengChain guide rail lifting cargo elevator, and that the travel switch points of each safety device must be safe and reliable.
Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, the motor still operates with full load, and the current flowing through the stator winding exceeds the rated current, leading to the motor stopping itself. If the stopping time is slightly longer and the power supply is not cut off, the winding will not only be severely overheated, but also burned. When a star connected motor is mistakenly connected into a triangle, or when several coil groups are connected in series into a single branch, the motor is mistakenly connected into two branches in parallel, both the windings and the iron core will overheat, and in severe cases, the windings will be burned.
