arsenicMobile small electric elevatorWhat are the outstanding problems in the industry

Construction electric elevators should be equipped with cable guide frames and comply with regulatory requirements.

The use of standard section connecting bolts should comply with the user manual and specification requirements.

arsenic.After the limit switch is activated,arsenicElectric elevator, only professional personnel can restore the movement of the suspension cage.

The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed.

.Steel wire ropes pulleys, and counterweight steel wire ropes shall comply with the following regulations: the characteristics of steel wire ropes shall comply with the requirements of General Purpose Steel Wire Ropes GB/T20118; Maintenance, deformation, the foundation should be inspected and accepted according to the requirements of the specifications. Only after passing the inspection can the installation be carried out.

The function of the lifting platform in a theater is roughly as follows: the main lifting platform arranged in the main performance area of the stage is mainly used to quickly change the scenery. Typically, with&quo; Product; In the music and dance theater stage arranged in a zigzag pattern, the lifting platform side car platform, and rear car turntable perform a rapid transformation of the entire or partial scene. This arrangement allows for rapid switching of three full sets.

The motor of the hydraulic guide rail lifting platform is set around the wellbore, occupying a relatively small area, improving the utilization rate of the wellbore area.

The coaxiality between the motor shaft and the worm shaft in the aluminum alloy electric elevator drive device should be less than 0.1mm, and there should be a 2mm gap at the shaft end to ensure that the motor bearings bear reasonable loads and reduce motor operating noise; electric

Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.

Quality assurance.Before installation, the installation unit should confirm that the foundation, foundation bearing capacity, embedded parts, and foundation drainage measures of the installed construction electric elevator and auxiliary heavy equipment comply with the requirements of the special construction plan for the installation and dismantling of the construction electric elevator based on the construction electric elevator foundation acceptance form, concealed engineering acceptance form, and concrete strength report.

The use of standard section connecting bolts should comply with the user manual and specification requirements.

When the door is closed, except for the gap between the lower part of the door that should not exceed 35mm,arsenicSmall electric automatic elevator, any through-hole and opening size related to the distance between any door and adjacent moving parts, as well as the gap around the door or the gap between parts,arsenicElectric mobile elevator, should comply with the provisions of Table 4 of GB 23821-2009.

Horizontal lead screw mechanical electricity

Administration.The spacing between wall brackets and the height of guide rails above the high attachment point should comply with the requirements of the user manual.

Setting requirements: Construction electric elevators should be equipped with a down travel (limit) switch. The down travel (limit) switch should be able to automatically stop the cage running at rated speed before reaching the lower limit switch.

There is no need to set up a computer room above the shaft like an elevator, and the top floor height can be installed at least 2.5 meters.

arsenic.The motor of the hydraulic guide rail lifting platform is set around the wellbore, occupying a relatively small area, improving the utilization rate of the wellbore area.

The bearing capacity of the building structure at the attachment point of the wall bracket should meet the requirements specified in the user manual for construction electric elevators.

Protective measures should comply with regulatory requirements.
