Hu GewenElectrThe quality of the standard section should comply with the product manual and specification requirements.
Setting requirements: The installation and dismantling workers, electricians,Hu GewenDedicated electric elevator, and other operators of construction electric elevators should have special construction operations.
Hu Gewen.Setting requirements: Steel wire rope electric elevators and reusable steel wire ropes should be equipped with anti loosening rope devices, which should have compliant loosening rope switches and be able to interrupt any movement of the cage until it passes through the
The net height of the landing door opening should not be less than 8m and the difference between the net width and the outlet width of the cage door should not exceed 120mm. When the floor door is closed, the size of any through-hole and opening related to the distance between any door and adjacent moving parts, as well as the gap around the door or between parts should comply with the provisions of Table 4 of 'Mechanical Safety - Safety Distance to Prevent Upper and Lower Limbs from Touching Dangerous Areas' GB23821-2009.
.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
From the perspective of the safety performance of the machinery itself, those that have undergone national safety certification will not have significant safety issues. The main problem is that after using the electric elevator for a period of time, mechanical components may fall off or be damaged due to various factors. This problem depends on regular inspection and maintenance of the machinery
When the door is closed, except for the gap between the lower part of the door that should not exceed 35mm, 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, should comply with the provisions of Table 4 of GB 23821-2009.
The inner bearing of the roller in the device is in good condition, and a complete grease film surface is maintained between the curved surface of the roller and the main chord of the aluminum alloy electric elevator. A good grease film surface can reduce wear and noise
The setting of the cable guide frame should comply with the user manual and regulatory requirements.
Where to sell API.From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, long service life, large load bearing capacity, and are relatively simple, making them suitable for use in stage equipment.
Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
When the wall bracket adopts non matching standard products, design calculations should be carried out.
Before installation, the installation unit should confirm that the foundation, foundation bearing capacity,Hu GewenDC electric elevator, 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.
Packaging strategy.The use of a lifting platform as a tool for storing performance blankets, soft scenery, etc. In some theaters, there is a soft scenery storage lifting platform located at an appropriate location on the stage for the storage of blankets, soft scenery, etc.
Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.
Safety performance: Electric elevators not only have the safety device of traditional traction elevators, the horizontal distance between the closed cage door and the closed landing door should not exceed 150mm. Otherwise, measures should be taken to make it meet the requirements, or side protection devices at the entrance of the landing station that meet the requirements should be equipped. The distance between any opening between the side protection device and the hanging cage or landing door should not exceed 150mm.
When the wall bracket adopts non matching standard products,Hu GewenElectric elevators for construction sites, design calculations should be carried out.
During the use period, the user unit should organize professional technical personnel to inspect the construction electric elevator monthly according to the standard requirements, and record the inspection results.
