Huanghua3 ton 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, 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.
The motor winding is short-circuited. When a short circuit fault occurs in the motor winding,HuanghuaFixed lifting cargo elevator, the short circuit current is much larger than the normal working current, causing the winding to overheat or even burn out.
Huanghua.When working in a hot environment, pay attention to heat dissipation.
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.
.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,HuanghuaThree story cargo elevator, 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, the windings will be burned.
For guideway elevators installed outdoors, they are often exposed to rain and sunlight, so special attention should be paid to regular maintenance and inspection to avoid accidents.
Unscrew the screws on the dustproof hole on the outer side of the elevator flange, adjust the PCS system ring to align its side hole with the dustproof hole, and tighten with the hexagon socket. After that, remove the motor shaft key.

Overview of manual hydraulic platform: Manual hydraulic platform is a small lifting mechanical platform, mainly used for small range lifting, lifting, moving, and placing of items, as well as handling small valuable items. The product has a generous and beautiful appearance, solid structure, stability, safety and reliability, and its performance and service life have reached the advanced level of the same equipment. Currently, the mainstream of the market is hydraulic driven lifting. Due to its compact size and convenient mobility, it is widely used in logistics and transportation, warehouse management, libraries, supermarkets, and ordinary small equipment manufacturing industries.
When a cargo elevator fails, it should be repaired by professional personnel. It is not allowed to modify the cargo elevator without permission.
Meticulous workmanship.Regardless of whether it is used outdoors or indoors, it is inevitable that some small problems will occur after a long period of time. At this time, ensuring flexibility and reliability. Long term improvement of the elevator factory, a 20 year old brand with competitive prices and guaranteed quality!
Knowledge popularization and superior performance of scissor fork type fixed lifting platform: equipped with safety devices to prevent overloading of the lifting platform; Equipped with a protection valve to prevent hydraulic oil pipe from cracking; Equipped with an emergency lowering device for sudden power failure; The doors of the upper and lower floors are equipped with safety devices that interlock with the system.
Connect the motor to the elevator naturally. During connection, it must be ensured that the concentricity of the elevator output shaft and the motor input shaft is consistent, and that the outer flanges of the two are parallel. Inconsistent centering can cause the motor shaft to break or the elevator gear to wear.
Customer first.Low cost: Compared to the scissor type mobile lifting platform, the cost is much lower. Therefore, when purchasing a lifting platform, it is necessary to consider the use range, frequency of work,HuanghuaFixed hydraulic lifting cargo elevator, load, and other factors of the lifting platform to select a lifting platform suitable for the work requirements.
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.
The brake operators of each mechanism on the equipment should regularly check and adjust the clearance of the brake shoe and brake wheel ensuring flexibility and reliability. Long term improvement of the elevator factory, a 20 year old brand with competitive prices and guaranteed quality!
Huanghua.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.
Walking: assisted self-propelled, two wheel traction, self driving, which increases the copper loss of the winding the short circuit current is much larger than the normal working current, causing the winding to overheat or even burn out.
