Ren QiuCargo eand 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.
Usage: Scissor fork type fixed lifting platforms are mostly used for goods transportation between height differences in production lines, loading and unloading materials, adjusting the working height during workpiece assembly feeding materials to loading machines at high altitudes, lifting components during assembly of large equipment, matching storage and loading sites with forklift trucks and other transportation vehicles for rapid loading and unloading of goods, vehicle lifting, fixed three-dimensional parking, and other places.
Ren Qiu.After careful inspection, it was found that there were two main causes: loss of hydraulic pressure and leakage of hydraulic valves or seals.
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, the National Quality Inspection Bureau strictly inspects this area. Any lifting platforms that are deemed to have safety hazards must be removed. Therefore, when personnel ask if you need to add guardrails, do not blindly refuse, 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.'.
.It is good for aerial work vehicles not to cover their clothes and park outside. If it is windy and rainy, 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.
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.
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!
It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.
Although the cargo elevator has good safety, in actual work, if you do not pay attention to detailed maintenance, there may be accidents, full consideration should be given to whether the on-site environment meets the operating conditions of the steam crane.
Safety and health.This fixed lifting device can also be used inside a warehouse, such as lifting a certain layer of the warehouse to transport goods or personnel to a designated warehouse location.
Scissor type fixed lifting platform is a transportation and loading equipment that transports goods from one height to another. After operation, the platform is level with the ground, without occupying ground space and affecting passage passage.
Unscrew the screws on the dustproof hole on the outer side of the elevator flange,Ren QiuTwo layers of hydraulic lifting cargo elevator, 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.
Is the water cooling and air cooling of the hydraulic station the same?
Affordable price.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, flameproof electromagnetic directional valve,Ren QiuThree ton lifting cargo elevator, throttle valve, hydraulic control one-way valve, 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.
When working in a hot environment, pay attention to heat dissipation.
The load of this series of products is divided into 0.1 to 0.8 tons, and can also be customized according to user requirements, with a load of up to 10 tons.
Ren Qiu.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.
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.
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.
