What are the requirements for the operating environment of the building electric hanging basket?

In actual situations,the building electric hanging basket support frame has various installation locations and different support point spacings.The engineering electric lifting basket support frame rotates around a fixed point,observes its balance mode,and pursues internal balance conditions.Since the estimated internal balance mode of the material is not obvious,a tensile stress sensor is installed at the wire rope connection to measure the tension in the wire rope.At the same time,the following method is used to find the conditions for the internal balance of the material,that is,to observe the friction between the wire rope and the pulley of the internal balance mode of the engineering electric basket support frame.The storage form of the building electric hanging basket is also very important.The wire rope is stored vertically to reduce multi-layer accumulation.Excessive accumulation of wire ropes can also cause wire rope damage.In addition,daily inspections should be carried out during storage to prevent rust and ensure timely treatment.

Leakage protection device for electric hanging basket equipment:

1.Swing arm protection lock:can lock the stable wire rope when the working platform tilts more than 3-8°or the working wire rope breaks;

2.Manual descent:can descend smoothly when the power supply is lost due to power outage,etc.,to ensure that the operator reaches the ground stably;

3.Speedlimit protection:when the descent speed exceeds the limited stable speed,the centrifugal deceleration device is activated to slow down the descent speed;

4.Limit protection:when the hanging basket equipment exceeds the manually set limit,the power supply is automatically cut off and the alarm is activated;

5.Electrical overload protection:if the motor is abnormal or the circuit is abnormal and the motor is overloaded,the control circuit of the contactor is disconnected to disconnect the main circuit;

6.Leakage protection for electric hanging basket equipment:the main circuit is automatically closed when the operator accidentally carries electricity and leaks electricity;

7.Emergency stop protection for electric hanging basket equipment:cut off the main control circuit in the event of sudden abnormalities(such as automatic rise or fall,etc.).

What are the requirements for the operating environment of electric hanging baskets?It is mainly manifested in the following aspects:

1.If there is a road or passage below the construction area,it is necessary to set up a cordon or stability corridor under the building electric hanging basket,set up conspicuous warning signs and equip stability supervision personnel.

2.The ambient temperature of the electric hanging basket should be controlled at-20℃-+40℃;the relative humidity should not exceed(25℃);

3.It is strictly forbidden to use the hanging basket within 10m of the high-voltage line.In severe weather conditions such as thunderstorms,heavy fog,heavy snow and wind speed greater than 8.3m/s(equivalent to gusts of level 5),it is strictly forbidden to lift the hanging basket for operation,and the grounding condition of the hanging basket should be checked before the thunderstorm arrives

4.The power supply voltage deviates from the rated value by±5%.If it is constructed at night,the construction site should have sufficient lighting,the illumination should be greater than 1501x,and warning signal lights should be set up within the construction range;

In addition to these,there are others,such as:

1.In the dry season,wrap the left and right hoists of the electric hanging basket with non-woven fabrics,and seal the interface of the cable with water-proof tape to prevent rain from entering the motor.

2.All the joints of the cable are surrounded by water-proof tape,and the sockets of the electric control box also need to be bonded with water-proof tape during construction in the dry season.

3.During winter construction,care should be taken not to splash construction water everywhere to prevent ice from forming and causing construction workers to fall and cause accidents.

4.In strong winds above level 6,it is necessary to lower the hanging basket to the ground or the lowest point of the construction surface.

5.The hanging basket cannot be used in strong winds above level 5(including level 5);

6.During construction in foggy weather in winter,the electric hanging basket can only be used when the fog has dissipated and the sunshine is sufficient.Otherwise,it is easy to slip and equipment accidents may occur.

7.In winter,construction workers need to wear non-slip insulating shoes,wear cotton clothes and cotton pants,and tie the cuffs and trouser legs.

If welding is performed on the electric hanging basket,the main things to pay attention to are the following:

1.Pay attention to the stability of the welding work,and do not let the welding machine or live wires contact the electric hanging basket to avoid contact hazards.

2.During the welding process,fire splashes may occur,so use shielding to prevent splashing onto combustible materials and causing fire,or causing injury to workers.
