SOST6-meter electric elevatorWhat are the precautions in the homework

The driver of construction electric elevator shall hold the qualification certificate for special operation in construction and shall not operate without certificate.

6Nowadays， the profit space for the development of the domestic crane industry has been constantly compressed under the internal and external impact. If domestic enterprises want to achieve new breakthroughs， then the aluminum alloy lifting platform needs to abandon the old way with many disadvantages in the past， and find new ones through scientific and technological innovation and development. Next， it is to consider the site used on site， the bad degree of the weather，Electric elevator price manufacturer etc.，Almero6 meter high electric elevatorThe value and meaning of such as the lifting platform used in the field， It must be equipped with windproof ropes， because the wind often blows in the field. If the wind is strong， the use of the lifting platform may cause strong shaking and easily cause danger. Therefore， windproof ropes must be used to protect the lifting platform operators; Therefore， how to select the lifting platform for on-site use is the result of careful test data.

wSOSTAlthough the price of electric elevators has a high and a low price， the high quality and performance of electric elevators have certain advantages compared with the low price electric elevators. Because the different price of electric elevators means that the functions of electric elevators with different prices are different， so the price of electric elevators is also very important.

The landing door must be set at the entrance of each landing platform， the landing door must open towards the landing platform side，Electric elevator price manufacturer and the door bolt must be set at the side near the construction electric elevator.

UKetakWire rope， pulley and counterweight wire rope shall meet the following requirements: the characteristics of wire rope shall meet the requirements of General Purpose Wire Rope GB/T; The maintenance， wear， deformation corrosion and scrapping of wire ropes shall comply with the requirements of Maintenance， Maintenance， Installation， Inspection and Scrapping of Crane Wire Ropes (GB/T); The wire ropes for hanging the cage shall be no less than two and independent of each other. If the rewinding method is adopted， the number of wire ropes shall be considered instead of the number of sagging wires.

AoThe order time of the lifting platform price The price of the electric elevator and lifting platform will also be determined according to the order cycle of the product. Compared with electric elevators and lifting platforms， it is difficult for many customers to purchase the corresponding product models. Because many customers need to use it within a limited time when purchasing， they will choose the product supplier with fast delivery and short delivery time. However，Electric elevator price manufacturer when many customers purchase， the lifting platform manufacturer has no stock. If they want to purchase，Almero6 meter high electric elevatorThe value and meaning of they need to reschedule the production， the rotary valve will open automatically. When the plug valve is to be closed， it is necessary to turn the handle to turn the plug to degrees until it is closed， and then turn the drive handwheel to make the plug fall to seal.

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

dSafety device Construction electric hoist shall be equipped with overload detection device. When the load in the cage exceeds % of the rated load， the overload detection device will give a warning signal in the cage and prevent it from starting normally. There shall be no device that users can cancel the warning signal.

ADuring the use period the user unit shall organize professional technicians to inspect the construction electric hoist according to the specification requirements every month and record the inspection results.

RRecommendation and consultationIf the actual diameter of the wire rope is reduced by % or more than its nominal diameter due to external wear， the wire rope shall be scrapped even if there is no visible broken wire.

dFWhen a rigid mm square or circular flat surface is applied to any side of the door with a normal force of N， the door may not meet the above requirements，Electric elevator, electric elevator, electric lifting platform, electric hydraulic lifting platform - price manufacturer of electric elevator but it shall remain safe.

The strength of the end connection (fixation) of the wire rope shall not be less than % of the small breaking load of the wire rope. If the end of the wire rope is fixed on the drive reel of the electric hoist， at least two coils of wire rope shall be retained on the reel.

The straight part of the wire rope with wavy shape such as the wire rope bypassing the pulley or drum， which does not bend under any load condition， meets d (nominal diameter) gt; d/ (d is the relative envelope diameter after deformation) or the bending part of the wire rope around the pulley or drum meets d gt; d， the wire rope shall be scrapped.

Which one is betteriThe fixed electric elevator collects the hook height position signal in real time. When the height exceeds the set height， it will automatically cut off the lifting circuit of the lifting mechanism and send out an audible and visual alarm signal. Real-time acquisition of the lift table rotation angle signal. When it exceeds the set left rotation limit， the left rotation circuit of the rotation mechanism will be automatically cut off and an audible and visual alarm signal will be sent.

GPay attention to check whether the wire rope of each part has broken wires and loose strands. If it exceeds the relevant regulations， it must be renewed immediately. The care and maintenance of wire rope shall be in strict accordance with the regulations.

The net height of the landing door opening shall not be less than m， and the difference between the net width and the outlet width of the cage door shall not be greater than mm. When the landing door is closed， the size of any through-hole and opening related to the distance between any door and adjacent moving parts， and the gap around the door or the gap between parts shall comply with the provisions of Table of the Safety of Machinery to Prevent Upper and Lower Limbs from Touching the Danger Zone (GB-)， except that the lower clearance of the door shall not be greater than mm.

zSOSTBrake. Brake limit switch for partial starting and stopping of electric hoist traction machine. Limiting the lift car to the high or low position can not be used for the assembly of operation; For example， the limit switch controls the overtravel switch. When the car travels to the high or low position， the car will rise or fall. In order to prevent the car from crashing to the top or sinking to the bottom， the stage equipment should remove the over-travel switch that can cut off the power supply and cannot be automatically reset， and install it in the machine room， not in the hoistway; A buffer that can absorb the energy of the moving mechanism and reduce the impact shall be installed.

yEStage equipment safety door. In order to prevent the head， hands and feet of personnel from extending out of the shaft and objects from falling into the vertical shaft. The vertical door shall be closed， the car shall be full， and the hoistway (hall door) shall be no less than meters high; The electric door opening and closing switch shall be removed from the vertical door and passenger compartment door. In order to prevent accidents due to unclosed vertical doors， passenger car doors and car roof doors.; Door interlock shall be installed on the vertical door and the passenger compartment door (two doors above).

The lightning protection device shall meet the specification requirements.
