Implementing multiple shifts of homework should fill in and submit records according to regulations.
Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door
Honolulu.The usual operation of landing and docking. The installation position of the upper limit switch should comply with the following: when the lifting speed is less than 0.8m/s, the upper safety distance L left after the upper limit switch is triggered by the hanging cage should not be less than
The counterweight guide rail should meet the specification requirements.
.Speed limit wire rope switch. When the speed limit wire rope trips or breaks. Make the electric elevator unable to start.
Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
The foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
Chain type electric lifting mechanism: With a good guiding mechanism, it can ensure that the equipment does not tilt during operation. Gear and rack electric lifting mechanism: precise transmission and high cost.
When charging, it is necessary to charge it in a timely manner. When the equipment is used for about 2 months (according to the actual frequency of use), it is necessary to add grease to the rotating parts once; Regularly inspect the working status of the pin shaft of the fully self-propelled electric elevator every month,HonoluluFixed electric elevator, and if any pin shaft is found
Setting requirements: Each landing entrance should be equipped with a landing door, which should cover the opening with its full width, and should not open towards the lifting passage.
Lets see.The foundation base or embedded parts should be fully embedded in the concrete foundation plate.
Emergency manual valve: In case of power failure, it can cause the car to descend to the nearest floor position and open the door
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, 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.
The full height landing door should meet the following requirements: the net height of the landing door opening should not be less than 0m. In special circumstances, when the net height of the building entrance is less than 0m, it is allowed to lower the height of the lower door opening,HonoluluNew electric elevator, but in any case, the net height of the lower door opening is not less than 8m. (Article 1 of GB26557-2011)
Professional is king.Acceptance: Concrete strength grade C30, strength testing report.
Construction electric elevators should be equipped with lower limit switches that are sensitive and reliable.
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.
Honolulu.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.
