OneGondola for working at heightSafety devices
1. Safety lock: The safety lock is one of the most important safety devices in the construction gondola, the protective wire rope penetrates into the safety lock along the direction of the arrow, when the power wire rope is suddenly broken or in a relaxed state, the construction gondola is fixed by the protective wire rope to ensure that the construction gondola will not fall.
The conditions of use that should be met for the use of safety locks:
1. Within the valid calibration period;
2. Have an effective lead seal or paint seal;
3. Use the specified wire rope;
4. Use under normal working conditions;
5. The working environment temperature is -20 +40;
6. Operated by trained personnel in accordance with the requirements of the instruction manual.
2. Upper limit protection device: the working principle of the upper limit protection device is the same as the working principle of the upper limit of the material hoist, and the limit plate is installed at the specified height at the upper part of the protective wire rope (about 1m from the top position), when the height of the hanging basket rises to the position of the limit plate, the upper limit contact contacts the limit plate, and the power supply is forcibly cut off.
3. Protective safety rope (hemp rope) with anti-slip buckle: The protective safety rope and anti-slip buckle are used together to ensure the last line of defense for the safety protection of operators. Therefore, it must be strictly managed in the daily safety inspection process.
The safety rope should use nylon safety rope, and the whole rope should be hung up, and should not be used for length
Each gondola is independently equipped with a safety rope, and the safety rope shall not be connected to any part of the gondola.
The operator in the gondola must tie the safety belt to the safety rope.
Safety ropespathThe size must be used in the safety latch calibrationRope diameter rangeand the safety lock should be sensitive and reliable. A safety latch can only be attached by one person.

On May 10, 2021, the Wuhan subway gondola accident caused a sensation because of the presence of personnel**. The Tianjin hanging basket incident on May 26 did not cause waves, although it was all swaying in the wind. I checked the latest information again, in fact, the same thing happened on April 14, and I was fortunately rescued by the fire and rescue detachment as well as the Tianjin hanging basket incident.
What is the reason? Is there a problem with the enterprise system? Is the system design unreasonable? Or is it a poor internal management that makes it impossible to avoid security risks? These are superficial, but the most fundamental and deadly reason is that they ignore the rights and interests of workers and even their lives.
Why did a tragedy that could have been avoided become inevitable?Look at such a recent event,Is it really an accident? IndividualEnterprises raise their pillows, think about it, a fluttering "draw inferences".Whether it's true or notDrainedThe "thunder" of the next accident.
