Implementing multiple shifts of homework should fill in and submit records according to regulations.
Safety grounding device. In order to protect against electrical equipment. The metal casing of electrical equipment and the metal structure of electric elevators should be equipped with a safety grounding device. The grounding wire should operate multiple wires, and the neutral wire should not be arbitrarily held as a safety grounding wire. Its grounding resistance should not exceed 4 ohms; The power supply of the electric elevator can be cut off.
arsenic.Folding arm electric elevators are mostly driven by hydraulic means, and the source of power for the hydraulic system is hydraulic oil. Only when the hydraulic oil quantity is sufficient and the oil quality is high, can the folding arm electric elevator provide greater torque output, thereby improving work efficiency. So how can we determine whether the newly added hydraulic oil quantity is sufficient? What is the hydraulic oil quantity standard?
When the foundation is set on the roof or floor structure, the bearing capacity of its supporting structure should be checked.
.Work is essential, and the main protective accessories include safety belts, guardrails, protective covers, platforms and stairs, etc.
Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value, the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops
Horizontal lead screw mechanical electricity
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.
Limit switches should be triggered directly by the movement of the suspension cage or its related components.
Setting requirements: The wall bracket should use the manufacturer's matching standard products.
Good reputation.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,arsenicElectric fork lift table, personnel and property losses.
After the electric elevator passes the inspection, the user unit shall organize the leasing unit, installation unit and supervision unit to conduct acceptance. For the implementation of construction general contracting, the acceptance shall be organized by the construction general contracting unit. The acceptance form should be signed by the relevant responsible person.
Vertical lead screw electric lifting mechanism: Adopting a lead screw transmission method, 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, Terrace, Tower, Pavilion; Ideal props.
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.
A complete range of products.Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value, the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops
The working principle of the aluminum alloy lifting platform is that hydraulic oil is composed of a vane pump to form a certain pressure, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve
In addition to ground protective fences, low level doors can be used. Low level doors should meet the following requirements: the height of the door should be between 1m and 2m. And there should be at least protective railings, a half height middle crossbar, and a toe board at least 150mm above the ground.
arsenic.Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, it is advisable to place the screw at the bottom and the nut at the top.
To ensure safe and reliable braking of the lifting platform and prevent accidents, a hydraulic control one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure. Electrical system explosion-proof button SB1&flash; The rotation of the SB6 motor and the commutation of the explosion-proof electromagnetic directional valve are used to maintain load increase or decrease, and; Program adjustment time delay to avoid frequent movement of electric elevators that may affect their service life.
