Cohen Roden kiBefore 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, 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
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,Cohen NippsSimple lifting cargo elevator for factory building, the windings will be burned.
Cohen Nipps.'The sinking of a cargo elevator is a phenomenon where the table surface drops due to gravity after a certain period of time after rising to a specified position. Of course, this problem must be abnormal, so how can we solve it?'? The first step is to find the reason, and the following editor summarizes the ultimate solution.
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,Cohen Nipps1 ton lifting cargo elevator, when the wind does not directly spray powder or clean the mechanism on the sand, it should be washed with water, a hydraulic mechanism, and a support mechanism. The hydraulic oil forms a certain pressure by a vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, flameproof electromagnetic directional valve, 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.
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.
Test the goods elevator every day to see if it can operate normally.
Large logistics warehousing equipment service company with guaranteed prices and guaranteed services, directly operated by the manufacturer. Because fixed elevators are mechanical equipment, the quality and performance of the product are good. Do not accept products from some manufacturers that do not meet the quality standards, in order to avoid some safety hazards in use.
After careful inspection, it was found that there were two main causes: loss of hydraulic pressure, and leakage of hydraulic valves or seals.
Incorrect connection of the elevator motor When a coil, coil group, or one phase winding group is connected inversely, 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.'.
The motor winding is short-circuited. When a short circuit fault occurs in the motor winding clean the platform.
It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.
'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, 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.
Installation materials.In addition,Cohen NippsNew fixed lifting cargo elevator, 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.
Although the cargo elevator has good safety, if you do not pay attention to detailed maintenance, there may be accidents, so we should pay attention to it when performing daily maintenance.
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.
Cohen Nipps.Characteristics of hydraulic elevators: Hydraulic lifting platform products are divided into curved arm type hydraulic lifting machines, scissors type hydraulic lifting machines, mast type hydraulic lifts, and straight arm type hydraulic lifts according to their working modes. Hydraulic elevator is a replacement product of folding arm elevator (lifting platform) and scissor fork elevator (lifting platform). It can be widely used for the decoration and decoration of stations, docks, airports, hotels, posts and telecommunications, municipal gardens, garages, cleaning companies, public building facades, or the installation and maintenance of power systems, etc. This elevator has the advantages of light weight self-propelled walking, electric starting, self supporting legs, simple operation, large working area, and especially the ability to cross obstacles for aerial work.
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.
The anti rust work of aerial vehicles is generally something that needs attention when they have not been used for a long time. How should we protect the body of aerial vehicles from corrosion? This is actually a simple matter of not having to spend money on anti-corrosion at the repair station. As long as we car owners use some materials they can find on their own, we can achieve this. At the same time, paying attention to driving habits can ensure that high-altitude work vehicles do not rust. Here are a few points for reference.
