BelfordFixed lIncorrect connection of the elevator motor When a coil, coil group, it can cause a serious imbalance in the three-phase current and cause the winding to overheat.
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.
Belford.Although the cargo elevator has good safety, in actual work, there may be accidents,BelfordProduction of lifting cargo elevators, so we should pay attention to it when performing daily maintenance.
It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.
.It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.
Test the goods elevator every day to see if it can operate normally.
It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.
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.
In our daily life today, hydraulic cargo elevators are also increasingly widely used and deeply loved by customers. As a lifting tool, the maintenance of cargo elevators should not be careless. The following editor will introduce the daily maintenance of hydraulic cargo elevators.

Quality recommendation.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.
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.
Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
What is the new price for fixed elevators? Professional improvement of the quality assurance of the elevator factory. Preferential activities are ongoing welcome new and old customers to consult
Finance Department.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, 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.
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,BelfordWorkshop lifting cargo elevator, 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.
What types of elevators are there? There are many types of such equipment, such as fixed lifting devices and vehicular lifting devices, depending on the form of movement. The so-called fixed lifting is generally installed in one place and fixed, and then lifting operations can be carried out. This type of lifting equipment is generally used more on the assembly line, and some large production lines need to lift the materials to a certain position when loading them, and then put them into production on the production line. A special lifting device needs to be fixed at a certain position on the production line.
Belford.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.
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,BelfordHigh performance elevator, and in severe cases, the windings will be burned.
