There is no need to set up a computer room above the shaft like an elevator, and the top floor height can be installed at least 2.5 meters.
From the above comparison, it can be seen that hydraulic electric lifting mechanisms have stable lifting, low noise, long service life, large load bearing capacity, and are relatively simple,KararaElectric wire rope elevator,KararaDedicated electric elevator, making them suitable for use in stage equipment.
Karara.The suspension cage movement can only be resumed after operator operation.
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.
.Small safe operation distance: Circuit voltage (kV) of external power lines<11~1035~110220330~550 Small safe operation distance (m) 4681015 Setting requirements: A small safe distance should be maintained between the outer edge of the construction electric elevator and the edge of the external overhead power line.
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, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.
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 foundation production and acceptance of electric elevators for foundation construction should comply with the user manual and regulatory requirements.
It is strictly prohibited to use travel limit switches as switches to stop operation.
Setting requirements: Before starting work every day and changing shifts, the driver of the construction electric elevator should inspect the construction electric elevator according to the requirements of the user manual and specifications, record the inspection results, and report any problems found to the user unit.
property right.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.
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 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.
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.
how much.Setting requirements: The spacing of wall brackets along the vertical direction should comply with the provisions of the user manual.
Greater than 0.04s; When the hydraulic buffer is used, the oil level shall be checked, and the action of the hydraulic buffer shall be monitored by the Electrical safety switch. When the hydraulic buffer is compressed, the cage shall not
The wall bracket of the construction electric elevator should be intact and reliably fixed, and its attachment distance, wall bracket spacing, and end height must comply with the requirements of the 'User Manual'. The angle between the plane of the wall bracket and the normal direction of the attachment surface should not exceed 8 degrees;. When the attachment device does not meet the requirements of the 'User Manual' due to conditions, its calculation sheet, design, and production materials should be confirmed by the manufacturer or reviewed by the technical leader of the installation unit, wide working platform, and high bearing capacity, making the high-altitude operation range wider and suitable for multiple people to work simultaneously. It makes high-altitude operation more efficient and safer
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, it will take on the function of raising or lowering. In order to prevent the lift car from crashing or sinking, rather than in the shaft; A buffer should be installed that can absorb the energy of the moving mechanism and reduce impact.
