LimestoneElectric elevator smallHow to deal with various development difficulties

As a material loading and unloading equipment recognized by customers in the lifting platform,LimestoneElevator manufacturer's electric elevator, the guide rail hydraulic lifting platform is superior in terms of product, civil engineering, and operating costs. The editor of the electric elevator will provide a detailed analysis: the advantages of the product are that the equipment bears a large load, and can be controlled up and down floors to achieve safe use.

The distance between the electric hoist and overhead line in Electrical safety construction shall meet the specification requirements, otherwise protective measures shall be taken.

Limestone.The installation position of the lower limit switch. The installation position of the lower limit switch should ensure that the contact plate triggers the switch when the rated load of the suspension cage decreases, causing the suspension cage to stop. At this time, the contact plate should also be close to the triggering of the lower limit switch

For customers to use and operate the lifting platform for a long time, the editor briefly introduces how to maintain and repair the lifting platform: First of all, normal maintenance is mainly focused on prevention, resulting in costly repairs.

.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.

When the horizontal distance between the edge of the cage and the edge of the landing or between the cage and the landing door is greater than 150mm and there is no effective protection from other structures, the side protection device for the landing entrance should be equipped.

During loading and unloading, the horizontal distance between the edge of the cage door and the edge of the landing station should not exceed 50mm.

Protective measures should comply with regulatory requirements.

Setting requirements: A limit switch should be set at both the upper and lower ends of the stroke, which should be able to cut off the power supply before the suspension cage and other mechanical stop devices (such as buffers) so that the suspension cage can stop

Pipeline rupture valve: When the hydraulic system pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descent

Quality improvement.When a rigid 5000mm2 square or circular flat surface is applied with a normal force of 600N to either side of the door,LimestoneMobile small electric elevator, the door may not meet the above requirements, but safety should be maintained.

Later when there is a major malfunction of the lifting platform, it should be repaired by professional personnel as soon as possible. After the malfunction occurs, it should not be used again to avoid accidents, personnel and property losses.

Setting requirements: The verticality deviation of the installation of the guide rail frame of the construction electric elevator should comply with the requirements of the user manual and specifications, as specified in the above table.

Acceptance: Concrete strength grade C30, strength testing report.

Economic management.Stage equipment safety door. To prevent personnel from extending their heads, hands, and feet out of the shaft and objects from falling into the vertical shaft. Its vertical position should be closed, its cabin should be full of doors, and the height of the hoistway (hall door) should not be less than 8 meters; The electric door opening and closing switches should be removed from the vertical and passenger compartment doors. In order to prevent accidents caused by vertical,LimestoneElectric folding elevator, passenger car doors, and car roof doors not being closed.; Door interlocks should be installed on both the vertical and passenger compartment doors.

Pole

Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.

Limestone.The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.

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.

Setting requirements: For construction electric elevators that operate in multiple shifts, the handover system should be implemented, and drivers should fill out the handover record form according to the standard requirements. The driver should conduct a pre shift inspection and confirm that there are no errors before starting the machine for operation.
