BohongHydrauliMotor 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, 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, both the windings and the iron core will overheat, and in severe cases, the windings will be burned.
Fixed elevator is a transportation equipment that directly lifts and loads goods from the ground. It is mainly used for goods transportation between height differences in production lines, material loading and unloading, component lifting during assembly of large equipment, fixed three-dimensional parking, eliminate hidden dangers, and eliminate faults. Doing so is beneficial to improving work efficiency, extending the service life of the equipment, and ensuring the safety performance of the elevator.
The purpose of hydraulic lifting platform Users can choose the power mode and configuration according to their own scope of use: power systems include: DC power supply, single-phase or three-phase power supply, diesel engine.
.Secondly,Bohong tribeElevating cargo elevator 1-4 floors, 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, 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, tighten it in a timely manner. Check the tightness of the connecting bolts of the equipment when the body is under pressure. All connecting shafts should be equipped with cotter pins; Check whether the operation of each mechanism is normal, 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, and that the travel switch points of each safety device must be safe and reliable.
In addition it is strictly prohibited to use a hammer during installation to prevent excessive axial or radial force from damaging the bearings or gears. Be sure to tighten the mounting bolts before tightening the tension bolts. Before installation, clean the anti rust oil on the motor input shaft, positioning boss, and elevator connection parts with gasoline or zinc sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.
It should be noted that compared to some lifting platforms in certain venues, protective barriers are generally added to the platform. As lifting platforms belong to special equipment, when personnel ask if you need to add guardrails do not blindly refuse, and consider whether it is necessary based on the site of use. 'In addition, it is necessary to possess two types of certificates namely, the Special Equipment Manufacturing License of the People's Republic of China and the Special Equipment Installation, Transformation, and Maintenance License of the People's Republic of China, before production, installation, and maintenance can be conducted. Therefore, it is necessary to ask the manufacturer whether they possess these two types of certificates.'.

Manual hydraulic platform classification: Manual hydraulic lifting platform vehicles can be divided into manual hydraulic handling platform vehicles, manual hydraulic stacking platform vehicles, and manual hydraulic shear type platform vehicles.
When a cargo elevator fails, it should be repaired by professional personnel. It is not allowed to modify the cargo elevator without permission.
Marketing Department.The purpose of hydraulic lifting platform Users can choose the power mode and configuration according to their own scope of use: power systems include: DC power supply, single-phase or three-phase power supply, diesel engine.
Goods should be stacked well on the platform, and should not be tilted. When the goods elevator is lifting or lowering beyond the scope of the platform, no one should stand around to watch.
Walking: assisted self-propelled, two wheel traction, self driving, and car modification.
Outriggers: mechanical outriggers, hydraulic outriggers, ordinary hand cranking outriggers, and pull-out outriggers.
Standard requirements.Walking: assisted self-propelled two wheel traction, self driving, and car modification.
Any kind of machine or equipment will undergo a series of inspections and debugging before leaving the factory, until all links are qualified. Take the mobile elevator for example,Bohong tribeProfessional cargo elevator, the same is true. Of course, during the internship, just mastering some specific information can effectively handle these questions.
The motor winding is short-circuited. When a short circuit fault occurs in the motor winding but if there is no contact,Bohong tribeHydraulic lifting cargo elevator, the short circuit current is much larger than the normal working current, which increases the copper loss of the winding, causing the winding to overheat or even burn out.
Bohong tribe.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.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
Prepare the foundation according to the foundation plan, pay attention to alignment, leveling, and alignment, and ensure the level of the foundation and various usage requirements.
