Drivers of construction electric elevators should hold special construction operations and are not allowed to operate without a certificate.
The list of materials for making landing doors is as follows: Table 1: List of materials for making landing doors. Landing doors should be installed at the entrance of each landing station, and the landing doors should function properly.
Houston.When a single steel wire rope is excessively stretched, it can achieve the lifting of a double-layer tabletop. Multiple lifting platforms can be formed as needed, and different steps can be formed within the travel range to meet the needs of meetings and performances; Pavilion,HoustonElectric barrier free elevator, Terrace, Tower, Pavilion; Ideal props.
.During normal operation, 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 distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.
Braking. The brake limit switch for partial motion control of the electric hoist traction machine. Assembly that restricts the operation of the lift car when it is opened to a high or low position; If the limit switch controls the overtravel switch. When the car travels to a high or low position,HoustonElevator platform electric, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, stage equipment should be dismantled with over travel switches that can cut off power and cannot be automatically reset, and installed in the machine room rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
Installation and dismantling personnel and drivers should hold certificates to work.
Construction electric elevators should be equipped with upper limit switches that are sensitive and reliable.
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, 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.
market price.Setting requirements: The main connection methods between the wall bracket and the building include: connecting the wall bracket with the embedded parts on the wall; Fix with wall bolts; Embedded bolts; Welding with steel structures.
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, except for the gap between the lower part of the door that should not exceed 35mm, 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.
The safety bulletin board for construction electric elevators should be hung at the protective shed of the electric elevator, with a size of 8 meters by 2 meters.
To meet the needs of stage craftsmanship and layout; Product; In the music and dance theater stage arranged in a zigzag pattern, auxiliary lifting platforms are often arranged in front back,HoustonDingli Electric Elevator, left, and right of the main stage lifting platform. The side and rear auxiliary lifting platforms are used for the smooth opening of the side platform and rear vehicle turntable, while the front auxiliary lifting platform is used to place the rear vehicle turntable near the platform entrance. The leveling lifting platform below the side platform and rear vehicle turntable can be used to level the platform after the side platform or rear vehicle turntable is driven out, so that the entire platform does not have a height difference, ensuring the safety of the cast members.
Test results.Especially suitable for steel structured factories, suitable for both indoor and outdoor installation.
Setting requirements: Construction electric elevators should be equipped with up travel (limit) switches.
The landing door should be in a normally closed state. Without the permission of the construction electric elevator driver, the landing door shall not be opened.
Houston.Construction electric elevators outside the lightning protection range
The angle between the wall bracket and the horizontal plane should comply with the requirements of the user manual.
Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.
