OneGondola for working at heightThe main species
The gondola is divided into manual, pneumatic and electric according to the driving mode.
The gondola is divided into climbing type and winch type according to the lifting characteristics. The difference between climbing and winch hoist is that the climbing hoist does not rewind or release the wire rope, it relies on the friction between the rope wheel and the wire rope as the driving force to drive the lifting of the gondola platform.
The model of the hanging basket for working at height is composed of class, group, type code, characteristic code and main parameter code and updated code.
The most widely used is the climbing electric aerial work gondola, the commonly used models are ZLP500, ZLP630, ZLP800, etc., the model of the gondola is based on our common ZLP630 as an example. Table 1 shows the size and counterweight of ZLP(D)630 standard hanging basket.

ThreeClimbWorking principle of electric hoist:
The basic principle of the basket lifting mechanism is that when the pen is wrapped around a rope and the rope is tightened upwards, the pen will move up and down when the pen is rotated.
The hoist is not to rewind or release the wire rope, but to rely on the occlusal friction between the drive wheel and the working wire rope, the wire rope is stationary when working, and the drive wheel crawls on it, so as to drive the hoist and the suspension platform to lift as a whole.

Let's recall the Wuhan gondola accident on May 10, 2021, and get a glimpse of our attitude towards the accident. After the accident, the body of the deceased and the mobile phone of the family were snatched away!
On the afternoon of May 10, 2021, Wuhan, windy weather. At the site of the wind tower supporting project on Sanyang Road of Wuhan Metro Group, two workers of Hubei Gaoyi Decoration Project, Yang Hao and Han Congfa, were doing exterior decoration operations outside the 17th floor. At 2:30 p.m., two people in the gondola called ** and said that the project was out of power and the gondola stopped running. Then a strong wind blew, blowing the hanging basket dozens of meters away, and then slammed into the outer wall of the building, blowing back and forth and hitting (some netizens ** as evidence). At 14:50, rescuers rescued the two people from the gondola without life, and then threw their bodies on the concrete floor of the 17th floor and covered them with a cloth. At about 5:30 p.m., the families of the two victims arrived at the site on the 17th floor of the project, and no one from Wuhan Metro Group and Shanghai Baoye Group, the general contractor, came forward to contact the families and negotiate the aftermath. At about 10:30 p.m., nearly 30 uniformed personnel arrived on the 17th floor of the project, and without saying a word, they began to grab the body of the deceased and the mobile phones of their families, and now the body is gone.
Yang Hao and Han Congfa should have died from violent impact and **.
First of all, this is obviously not an accident caused by force majeure, but caused by inadequate management, Wuhan gale has long had a weather forecast, windy weather is strictly forbidden to work at height, the construction party, the construction party has an unshirkable responsibility;
Secondly, the emergency rescue was not timely, after the power failure of the project, the victim called ** in the hanging basket for help, and the construction party and the construction party failed to take effective emergency rescue measures in time, resulting in the death of the two.
Third, after the incident, the construction party and the construction party did not come forward or contact, but instead dispatched personnel to snatch the mobile phones of the family members and the body of the deceased, which is blatant evidence of destruction.
According to the family members of the deceased, although the two deceased were employees of Hubei Gaoyi Decoration Engineering, the unit did not sign a labor contract with them, nor did they purchase social security and accident insurance.
Yang Hao and Han Congfa are typical migrant workers, with "three nos" (no social security, no urban hukou, and no labor contract), and there is no guarantee once there is a ** accident.
