Before the worker arrives at the ladder head to work and the ladder head starts to move, the sealing of the ladder head should be reliably sealed.

DL 5009.3-2013 part 3 of the power construction safety protocol: the specification of the transformer substation on the construction ladder is as follows:

3.5.21 ladder:

1. the materials, dimensions and manufacture of the ladder should meet the requirements of the current national standard GB/T17889 ladder (all parts).

2. The movable ladder is suitable for work with a height below 4m and which can be done in a short time.

3. The ladder should be solid and reliable and should be inspected prior to use.

4. The use of the ladder should meet the following regulations:

The common cat ladder comprises a left vertical rod, a right vertical rod and a plurality of ladder cross bars which are uniformly distributed in the middle, and the vertical rods are fixedly connected with the ladder cross bars. The two ends of the vertical rod are usually made into a form of being narrow at the upper part and wide at the lower part so as to obtain better stability. Nevertheless, the conventional ladder has the following disadvantages that it is difficult to meet the strict requirements of the power industry.

1) When the ladder is used on a telegraph pole or a steel pipe bracket, because the upper part and the lower part of the ladder lack firm fixing points, the erection is not firm enough, and the ladder can slide off the telegraph pole or the steel pipe bracket due to left and right shaking, so personal injury is easily caused. Therefore, special persons are required to support, constructors are required to support the ladder by one to two persons on the ground during the process of ascending and descending the ladder and working on the ladder, so that the labor consumption is large, the labor cost is high, the human resources cannot be fully utilized, and the construction progress is affected.

2) The ladder lacks a falling prevention device and does not meet the requirements of electric power safety working regulations; when constructors climb the ladder to transfer positions up and down, safety belts are needed to be used for preventing falling, the safety belts are alternately hung on firm components of the ladder up and down, operation time is long, and the risk that the ladder and the personnel fall simultaneously is possibly caused.

3) The included angle between the ladder and the ground cannot be determined, and when the included angle between the ladder and the ground is 60 degrees, the upper plane of the ladder step is not in a horizontal state and the anti-skid design is lacking;

4) The upper end and the lower end of the main column of the ladder lack of anti-skid measures or enough anti-skid capability, so that the anti-skid measures are difficult to play a practical role when people climb a pole.

To accommodate the power industry, new types of ladders have also emerged, such as:

in the novel ascending insulating ladder with safety belts (patent number 201821634606.0 bulletin day 20191018), safety semicircle rings are fixedly connected to the outer side walls of two insulating ladder rods, the safety belts between the waists are tied on the staff, the safety belts between the waists comprise a second elastic safety belt rope and a pair of annular buckles, the second elastic safety belt rope and the pair of annular buckles are fixedly connected, the insulating ladder safety belts are connected between the two annular buckles, rapid and firm binding between the safety belts and the ladder hanging points can be achieved, the safety belts are not easy to fall off, and safety accidents are not easy to occur.

In the chinese patent application "ladder with safety placement angle indication function" (patent application number 202010974123.0, publication No. 20210108), a placement angle indication member is disposed in at least an inner cavity of one of the rungs, and an operator can clearly know the placement angle of the ladder through the angle indication member.

In the Chinese patent application "an anti-skid ladder" (patent application number 202010130212.7, publication date 20200612), an anti-skid belt is arranged on the ladder body, so that the ladder can be effectively prevented from sliding and the safety in transferring articles is improved.

In the Chinese patent application "a novel anti-skid ladder" (patent application number 202111053233.4 discloses a day 20220128), when the inclined angle of the ladder body is overlarge, the supporting block is stressed to drive the lantern ring to rotate through the balls, so that the supporting block is inclined to a proper angle to support a user, and the top plate and the blocking block are arranged to support the elastic strip I and the supporting block through the blocking block, so that the stability is higher, the supporting effect is good, and the safety of the user can be effectively ensured.
