NejackLifting 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.
Outriggers: mechanical outriggers, hydraulic outriggers, ordinary hand cranking outriggers, and pull-out outriggers.
Nejack.When using, the four legs should be firmly supported on a solid ground (subject to the fact that the walking wheel is about to leave the ground). Sleepers can be used when necessary.
Does the cleanliness of the hydraulic station have relevant rules and requirements?
.Incorrect connection of the elevator motor When a coil, coil group, 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.

What is the new price of fixed elevators? Fixed elevators are currently very popular in the market. Due to different manufacturers, different materials, different load ratings, and different brand awareness, the prices also vary. Currently, the prices of fixed elevators produced in the domestic market are: rated load 1-5 tons, lifting height 7 meters, table size 2500 mm * 2000 mm, and the price is around 27000-45000 yuan; The rated load is 1-3 tons, the lifting height is 0 meters, the table size is 2300 mm * 2000 mm, eliminate hidden dangers full consideration should be given to whether the on-site environment meets the operating conditions of the steam crane.
The daily maintenance of guide rail type lifting equipment should pay attention to regular inspection and maintenance, extending the service life of the equipment, and ensuring the safety performance of the elevator.
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.
market.Frequently check for water accumulation and humidity. It is inevitable for aerial vehicles to drive in rainy and snowy weather,NejackElevating cargo elevator, 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, 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.
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,NejackGuide rail lifting cargo elevator, 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.
Fixed elevator is a transportation equipment that directly lifts and loads goods from the ground. It is mainly used for goods transportation between height differences in production lines, material loading and unloading, component lifting during assembly of large equipment, fixed three-dimensional parking, and other places. So what is the new price for fixed elevators?

Encyclopedic knowledge.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,NejackFixed hydraulic lifting cargo elevator, what we should do is to maintain and maintain the elevator. How to follow the steps correctly becomes a difficult problem. Let me explain it to you.
How to install and use the bearings of the elevator During the process of installing the bearing device of the elevator, which inevitably leads to some devices not in place or bearing misalignment. Once these problems occur in the device, the clearance between the bearings becomes too small, and then the inner and outer rings of the bearings cannot be located at the same rotation center. Therefore, when installing bearings, it is necessary to use specialized tools, and in the future, it is also necessary to use a detector to test the bearing device, so as to ensure the success of the bearing device.
The cleanliness of the hydraulic station is an important aspect of the elevator hydraulic station, so it should not be taken lightly. Moreover, from a professional perspective, there are relevant rules and requirements. You should refer to the specification manual, so that you can have a correct understanding and know how to achieve better cleanliness.
Nejack.Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
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, and the use of elevators and lifting platforms shall be checked
Incorrect connection of the elevator motor When a coil, coil group, 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.
