Seventeen green ancient cityThe cargo elevator isCommon faults and solutions

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, hydraulic lifting platforms are more widely used.

Seventeen green ancient city.The main structure and use of the guide rail type elevator are closed gear transmission, and the large and small gears are made of steel. After quenching and tempering treatment, they belong to the soft tooth surface. As the common failure form of closed soft tooth surface gear transmission is tooth surface pitting, the design is based on the tooth surface fatigue strength and checked based on the tooth root bending fatigue strength. The bracket bracket is used to fix and support all mechanical parts and some electrical components of the elevator chassis. It is mainly welded from parts such as side plates, connecting tubes, and connecting pieces. The materials are all selected, including the thickness of both sides of the plate, products, and tens of millions of products. Professional elevator factory transactions are safe and guaranteed. At the same time, in order to reduce the weight of the bracket, many process holes are designed on both sides of the plate. The worm gear and worm mechanism has the advantages of large transmission ratio, compact structure, small impact load, stable transmission, low noise, and has the characteristics of reverse self-locking. It can ensure that the transmission mechanism can self-lock when the motor is powered off during patient handling, so a worm gear reducer is selected. The involute worm is used, stable transmission, vibration absorption and noise reduction, light weight, wear resistance, and self reliance, making the design of the elevator more humanized.

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.

.Nowadays, container, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting requirements of different operation heights, and can be equipped with various table forms (such as ball, roller, turntable, steering, tipping, telescoping), and with various ways (separate, linkage, it has the characteristics of stable and accurate lifting, frequent starting,Seventeen green ancient cityElevating cargo elevator, and large load capacity, Effectively solve various lifting and lowering operation difficulties in industrial enterprises, making production operations free. Professional elevator factory has advanced technology, strict testing, more affordable prices, and more preferential treatment. Welcome to consult

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, 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,Seventeen green ancient city4-ton cargo elevator, and its rated pressure overflow valve is adjusted. Observe the reading value of the pressure gauge on the pressure gauge.

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.

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 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.

Potential development.Frequently check for water accumulation and humidity. It is inevitable for aerial vehicles to drive in rainy and snowy weather, or muddy roads. The bottom and some gaps and indoor floors are prone to sludge accumulation. If the owner does not clean them in a timely manner, this can cause moisture to hide. Therefore activities in the outer edges of wheel hubs, doors bottom corners of tree trunks, key holes, and wiper brackets, as well as other areas, should be regularly inspected, and the drainage holes in the doors and various parts should be kept unblocked to ensure that the car seat covers, such as humidity, carpets, and floors, prevent rust from forming parts.

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, 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.

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, and consider whether it is necessary based on the site of use. 'In addition, 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,Seventeen green ancient cityElevating cargo elevator factory building, 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.'.

Goods should be stacked well on the platform and should not be tilted. When the goods elevator is lifting or lowering beyond the scope of the platform, no one should stand around to watch.

system.Incorrect connection of the elevator motor When a coil, or one phase winding group is connected inversely, it can cause a serious imbalance in the three-phase current and cause the winding to overheat.

Main structure and purpose of guide rail type elevator: The mechanical part of guide rail type elevator mainly includes three parts: lifting device, track device, and belt changing device. The lifting device is mainly used to suspend the lifted person, which is the core part of the entire mechanism. The role of track device is mainly to provide movement trajectory, making operation more smooth. The belt changing device is used to switch tracks when the elevator is about to pass through the door. The internal structure of the lifting device is mainly composed of a gear mechanism, a bracket, a worm gear a guide mechanism, a lifting arm, upper and lower shells, etc. Gear mechanism Gear mechanism mainly includes large and small gears, winding pulley, central shaft, and safety device composed of stop buckle and torsion spring.

Test the goods elevator every day to see if it can operate normally.

Seventeen green ancient city.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, 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, 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.
