corkChain guidSeveral types: motor winding open circuit. When one phase of the motor winding is open circuit, or one of the parallel branches is open circuit, it will cause three-phase current imbalance and cause the motor to overheat.
Before 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, 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
cork.Manual hydraulic lifting platform application Manual hydraulic platform performance: The manual hydraulic platform truck is made of high-strength steel, with a reasonable and compact design structure, safety, stability, and reliability. It is equipped with a safety valve, a fully sealed oil cylinder, and a manual hydraulic system for lifting and lowering, making it easy to operate. Equipped with a guide wheel to save the operator's physical strength, and can protect the load wheel and pallet load wheel. Unique hydraulic pump design, the pump is simple and designed to maintain an ideal height for pipeline loading and unloading operations; The unique design concept makes the operator's operation simple and convenient.
Carefully prepare a special construction plan for installation and construction, 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.
In addition to having a fixed mode, there are also types of mobile elevators. As the name implies, it is a combination of lifting equipment and on-board systems. This type of lifting equipment is very flexible to move, and of course, it is better to use it. For example, there are such lifting equipment in airports, and stations or stadiums may also be equipped with such equipment, as it can be moved by itself The scope of work is not limited to a certain place, but can be used wherever lifting operations are required. For example, when installing outdoor advertisements, some advertisements are relatively high in height. At this time, mobile lifting equipment can be used to send billboards or staff to a designated height for work. This type of equipment can also be divided into two types according to the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is the use of hydraulic oil to drive to achieve a specified height. The electric mode is driven by a motor or tooth to lift to a certain height. However, currently, hydraulic lifting platforms are more widely used.
Safety performance: The lifting structure is made of high-strength manganese steel rectangular tubes, with a scissors type mechanical mechanism, easy to maintain, strong stability, and high bearing capacity. The lifting height is about 10 meters, and the load capacity is about 10 tons.
Does the cleanliness of the hydraulic station have relevant rules and requirements?
'Before installing the elevator bearings, we should never open the packaging prematurely. This can easily lead to premature bearing contamination, which can lead to premature bearing damage. In addition, when installing, it is necessary to ensure that the device environment is clean and not to bring iron filings, dust and other things into the bearings, as even some small dust,', If it continues for a long time, it will also affect the running-in between bearings, leading to a decrease in the life of the elevator.
Corrosion prevention measures for the body of aerial work vehicles Attention to small scratches The paint surface of aerial work vehicles often corrodes. In addition to common collisions scratches, and small rocks on the drive tire, there can also be a paint peeling point that can cause a small rust over time. Because most of these scars are small and easy to ignore. Therefore, regularly inspect the engine compartment lid and surrounding areas, and once found go to a professional beauty shop for processing in a timely manner.
Discount.The motor winding is short-circuited. When a short circuit fault occurs in the motor winding, 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.

Nowadays, small and medium-sized enterprises are products with the idea of good quality and preferential prices.
Unscrew the screws on the dustproof hole on the outer side of the elevator flange,cork4-ton cargo elevator, and tighten with the hexagon socket. After that,corkElevating cargo elevator, remove the motor shaft key.
Finance Department.Several types: motor winding open circuit. When one phase of the motor winding is open circuit, or one of the parallel branches is open circuit, it will cause three-phase current imbalance and cause the motor to overheat.
Many times, when ordering a large lifting platform, after the customer has determined the parameters, the designer will first consider various factors before designing, to prevent it from being difficult to transport to the customer's installation site after being too wide. Therefore, during design and manufacturing, it is also necessary to consider the bearing capacity of the split, design and manufacture on the premise of ensuring the load capacity and stability, and ensure that the equipment can be easily transported, lifted, and moved.
Hydraulic lifting platforms are widely used in factory maintenance, municipal construction, and decoration of hotels in industrial and mining enterprises, with reliable quality and perfect performance.
cork.The hydraulic lifting platform can be divided into four wheeled mobile type, two wheeled traction type, vehicle modified type, vehicle type, auxiliary self-propelled type, and the lifting height varies from a meter to 1 meter.
'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.'.
