Single brake to double brake of elevatorIn the early days, elevator traction machines were mostly one-way brake structures. There were hidden dangers such as ineffective or even non-operation due to their own quality or lack of maintenance, and a failure of one side of the brake arm would still cause safety accidents. Now, the country forced the use of double-directional brake traction machines.
There are some difficulties in modifying a tractor with a one-way brake structure into a tractor with a two-way brake structure. Because the traction machine was generally located in the engine room, the environment of the engine room was poor, and it was inconvenient for technicians to operate it. Moreover, the initial design of the traction machine with a one-way brake structure did not consider the subsequent transformation factors. During the transformation, it was necessary to carry out processing operations such as welding, drilling and polishing on the installation platform of the frame on the spot, which was more troublesome. The transformation efficiency was low and the cost was high, so the transformation effect was often not achieved.
However, there were also improvement plans. For example, there was a tractor that was modified from a one-way brake structure to a two-way brake structure, which included a frame, a brake wheel, a brake, two brake arm components, and other components. The frame was equipped with an installation platform, the brake was installed on the installation platform, and the two brake arm components were symmetrical on the frame on both sides of the brake wheel. The two side walls of the installation platform were connected to two adjusting screw rods, and the brake was a two-way brake. The outer ends of the two movable mandrils at the two ends of the brake arm assembly are propped against the inner walls of the upper ends of the two brake arm components. The mounting platform is connected with a transition plate, and the brake is fixedly connected to the transition plate through a screw. This method was easy to operate, and there was no need for complicated procedures such as welding and drilling.

Rebuild on the spotOn-site reconstruction referred to a method of rebuilding or transforming the original site. It could help the residents of the affected areas to quickly restore production and life in post-disaster reconstruction, while retaining the original community ties and cultural customs. In some countries and regions, on-site reconstruction had been successfully applied. For example, Japan adopted the method of on-site reconstruction in the post-earthquake reconstruction. In China's rural areas, the reconstruction of old houses in the countryside needed to go through the corresponding procedures. The specific requirements might vary from region to region. In urban regeneration projects, on-site reconstruction was also widely used to improve the quality of living and the image of the city. Cities such as Beijing and Guangzhou had introduced policies to allow residents of dilapidated buildings to rebuild or move back. In general, rebuilding on the spot could provide better living conditions for the residents while preserving the original community and social network.

Reaction distance, brake distanceReaction distance refers to the distance the vehicle traveled within the driver's reaction time, including the brake reaction time (from the discovery of the stimulus to the movement of the foot to the brake pedal), the brake action time (from the start of the brake pedal to the maximum braking force), and the continuous braking time (from the maximum braking force to the car stopping).
Braking distance referred to the distance traveled by a vehicle from the beginning of braking to the complete standstill of the vehicle when the vehicle was moving at a certain speed. It was the distance traveled by the vehicle from the moment the driver stepped on the brake pedal to the moment the vehicle came to a complete stop at a certain initial speed. It included reaction distance and braking distance. The smaller the braking distance, the better the braking performance of the car.
The length of the reaction distance depended on the driving speed and reaction time. The higher the driving speed or the longer the reaction time, the longer the reaction distance. The reaction time was directly related to the driver's sensitivity and technical proficiency. Usually, the reaction time was 0.75 to 1 second. For example, when the driving speed was 30 km/h and the reaction time was 1 second, the reaction distance was 8.33 meters.
The length of the braking distance was related to the driving speed, the braking force, and the friction coefficient. The higher the driving speed, the longer the braking distance. The driving speed was proportional to the square of the braking distance. The calculation method (commonly used internationally) was: Braking distance = vehicle speed/10 * 3+ vehicle speed/10 * vehicle speed/10, but there would be differences if the tires were different (such as summer tires and winter tires) or the road conditions were different.

How to solve the brake reboundThere may be the following reasons and solutions for the rebound after stepping on the brake:
1. ** brake oil problem **: If the brake oil pump has a problem due to insufficient brake oil, brake oil needs to be added.
2. ** Front wheel axis problem **: You can try to adjust the nut of the brake cable and brake unit to solve it. If there is no spring to assist, press the brake handle to see if the brake line can move freely. If it is too tight, it may require professional repair.
3. ** Problems related to the brake cylinder **: The brake cylinder does not return to its original position, causing the brake cylinder and the brake callipers to keep pressing against the brake pads. The brake return spring is too soft, causing the brake pedal to not fully rebound. The brake master cylinder does not return oil well, causing the pressure in the brake pipe to be high. These problems need to be repaired by professionals.
In addition, when the driver stepped on the brake pedal and felt the rebound, if the vehicle was equipped with the Anti-lock Braking System (abs), the activation of the ABS system during emergency braking would cause the brake pedal to have a pulse-like rebound feeling. At this time, you should continue to press the brake pedal hard to ensure that the ABS system is working properly. This will help shorten the braking distance and maintain control of the vehicle.
