Safety ladder practical knowledge

There are three common climb trapezoidal styles:

First, the traditional pole type, each rod member connected through the fastener, after connecting, the outside with a soft safety net cover.

Advantages: simple structure, mass production, low transportation costs

Disadvantages: poor stability, poor security;

Second, the frame type detachable ladder, all parts connected by standard parts after assembly is a square frame, surrounded by a metal guard net.

Advantages: The stability and safety are greatly improved compared with the rack-type, suitable for mass production, and the transportation cost is low;

Disadvantages: The workload of on-site installation is large. Most of the components need to be connected through standard parts; each connecting part needs regular inspection and fastening.

Third, the overall framework of ladders, also known as ladder cage ladder cage: the entire ladder cage is a welded together as a whole structure, including pedestrian ladders, pedestrian ladder handrails, walking platform and around the metal protection net.

Advantages: 1, strong bearing capacity: the overall use of frame structure, good stability; large space size, high structural strength, overall stability, high safety factor, can meet more than one person at the same time up and down, can provide for construction and inspection, supervision personnel Safe, comfortable and convenient upper and lower passages;

2. Safe and reliable: There is a metal safety net around the door, which is fully enclosed and can prevent falling and climbing. There is a security door on the entrance and exit section, which can be locked.

3, simple installation: Each component is a standard universal module, strong interchangeability, each section is connected through standard parts, installation and disassembly convenient and quick, greatly speeding up the construction progress;

4. Low use and maintenance costs, good comprehensive benefits: Standardization of component series, ease of management and transportation, no fragmented and easy to lose components, few parts that are easy to damage and easy to lose in the transition process, high reuse, almost no maintenance and repair costs Loss is low, and the use and maintenance costs are very low in the later period.

Disadvantages: Higher transportation costs and storage space.

Industry trends and market analysis:

With the improvement of people’s safety awareness and the improvement of supervision and inspection of safe production by the corresponding government management departments, the use of box-type safety cages will become more and more extensive, especially during the construction of subways and high-speed railways, pits and viaducts. The number of piers is large, and the requirements for safety precautions are relatively high. Most of them use box-type ladder cages. It is believed that the box-type safety ladder cages will bring more and more safety protection to more and more people and become a major engineering construction process. Safety equipment is preferred.
