Jiangmen aerial vehicle rental lift everyone: Crane Crane refitted into aerial work vehicle hidden danger.

The difference between crane refitting and aerial work vehicle:

1. Whether it has guarantee function

Different from lifting machinery, due to the high risk of high-altitude operation, aerial work vehicle has made great efforts in the support capacity. The aerial work vehicle is equipped with control devices in the working bucket and on the slewing seat to remotely control the start / stop, high speed / low speed of the engine. The electro-hydraulic proportional valve is used to control the action of the arm. The working arm can rotate continuously from left to right. The level of the working groove can be maintained automatically by the linkage mechanism. When the main pump fails, the emergency pump can be operated to lower the working groove, and the lighting at night is provided

Alarm and other functions. However, the modified crane has no protection function. Once the crane fails, the workers in the basket will not be able to help themselves.

2. Differences in design points

As mechanical equipment, each design covers the painstaking efforts of designers. Aerial work vehicle, simply speaking, is a tool to send people to high-altitude construction, which determines that every design on the vehicle needs to ensure the stability of personnel in the basket. Therefore, whether it is hydraulic or electrical system, the first thing to solve is the stability and stability of the equipment when it moves. Because every shaking will bring psychological and physical discomfort to the operators. The crane naturally takes the lifting capacity as the key point of design, and a certain range of shaking and the elastic bending of the boom under load are usually not considered.

3. The gap of operation ability

Aerial work vehicle, generally can be divided into straight arm type and curved arm type, especially curved arm type aerial work vehicle. Through the rotation ability of folding boom and hanging basket, the flexibility of aerial work vehicle is greatly improved, so that it can extend independently in a narrow space. With the operation function in the basket, the working efficiency is ensured. The modified crane obviously does not have such ability.

It can be seen that although the modified crane is similar to the aerial work vehicle, it is not the same kind of product, otherwise it will not belong to two industries. It's funny to call a deer a horse. And in the high-risk industry such as high-risk work, the consequences not only involve violations, but also a kind of disrespect for life.
