Wreckers sometimes encounter certain problems when dealing with traffic accidents. This may result in a significant reduction in the working efficiency of road wreckers. This will not only delay the wrecker's rescue time when a major traffic accident occurs, but also delay the rescue of victims on the accident vehicle and may result in Life-threatening accidents.
Road wreckers are the first-choice special tools for handling traffic accidents and vehicles that are in trouble. To enable them to operate efficiently in traffic and rescue, they rely on cooperation in many aspects:
First, command and dispatch system cooperation:
The biggest feature of road traffic accidents and vehicle breakdowns is "burst", which requires timely processing time. Therefore, it is very important to command the rapid response of the "central" dispatch system. A rescue company and a regional emergency response system often have an information platform and collect relevant information from various sources at any time. After obtaining the accident information, the command center must first consider the basic road conditions of the accident site, the size of the accident, the size of the vehicle in question, the material carried, and the severity of the damage. Then arrange how many vehicles with large tonnage are to be rescued. . For example, in the case of a failure in a small car accident in a lane in Hutong, a small wrecker or motorized wrecker that can be turned on the spot can be sent to the rescue; if container trucks and cement mixers topple over on the highway, the driver’s safety is threatened. In addition to sending one or two wreckers to participate in the rescue, they also need to have enough rescue tools. Secondly, from the perspective of saving resources and striving for time, mobilize nearby vehicles to quickly go to the rescue. In a very short period of time, it is necessary to think and straighten out a series of problems and make decisive decisions. This requires that command and dispatchers must establish a holistic view, have a strong sense of responsibility, and have strong ability to respond quickly.
Second, the basic functions of vehicles with:
The current road wreckers are being developed in the direction of "one vehicle with multiple capabilities". Designers are trying to make a wrecker capable of solving all traffic accidents. However, due to the short history of the development of wreckers, many technical problems are still in the exploratory phase. The current "plurality of vehicles" that can be prayed for is still impossible to achieve in one step, and many of the wreckers are limited to costs and are not The vehicle is configured too comprehensively, but at least the functions - lifting, lifting, dragging, rotating, winch and other functions should be available. If the functions of the wrecker are too simple, it is often necessary to use two or three wreckers with different functions to complete the rescue. This will result in time-consuming wreckage, which will seriously affect the efficiency of wrecking and rescue, and will hinder the rapid response of wrecker operations.
Third, the allocation of special equipment:
There are two aspects here. One is the special equipment configuration. Although there are few cases of evacuation, they are rare, and they are difficult and risky. For example, gas leaks from gas tankers and chemical spills from tank trucks require relevant fire extinguishing and anti-chemical equipment. Without these forest materials, rescue work cannot be started. The second is the configuration of special tools. At the scene of an accident, there may be trapped passengers and even life threats. Wreckers should be equipped with electric saws as soon as they are removed, and they can participate in the rescue at any time. What if the front or rear wheel of a small private car is locked in an accident? In the case of towing, it is necessary to cooperate with the auxiliary wheel; during nighttime obstacle clearing operations, the light on the road is poor, and ultimately, the high-power lighting vehicle helps, and the “ice cream cone†within the scope of clearing the obstacles must not be missing. These basic accessories must all be fully equipped, otherwise it will affect the efficiency of rescue.
Fourth, the operator's quality with:
The wrecker is a special working vehicle. The focus of work will change with the height and time of lifting and lifting. Operators must undergo professional training and pass the examination before they can take up posts. At the same time, they must regularly carry out exchange activities. Cases, improve the operation level. The technical maturity of operators should be reflected in the following aspects: First, they must understand the basic performance of the vehicle, be skilled in using tools, and understand the issues that need attention during each operation. The second is to learn to protect yourself and avoid the risks that may jeopardize yourself in your rescue. The third is to protect the site, pay attention to the safety of the personnel handling the scene of accidents and vehicle clearance work, and try to avoid causing traffic jams and injuries to the surrounding personnel, as well as damage to the scene of public property. The fourth is to think more about the victims and try their best to reduce the secondary damage to the rescued vehicles. A successful rescue requires a lot of cooperation, but high-quality operators often play a key role.
V. Coordination of functional departments and parties:
There is no administrative law enforcement function in the existing laws and regulations for the wreckers and rescuers. In the process of dealing with traffic accidents, they have taken on the special mission of occupying the roads for “violation†operations. This will certainly result in the smooth flow of roads. Impact. Therefore, its behavior should be recognized by the traffic management and traffic police departments, and it should be given strong support and cooperation to do a good job in the protection of accidents and the flow of passengers and traffic during road trips. (The work in this area has always been coordinated. Very good); accidents and faults of the driver and driver must actively cooperate with the scene, the passing vehicles should obey the command of the traffic police, according to the relevant instructions, color, slow down through the work area.
Sixth, vehicles with regular maintenance:
Wreckers are a constant emergency tool, and regular maintenance and maintenance work are very important. If there is no maintenance, it may not be drawn and used as soon as it is needed.
In routine maintenance, it is necessary to inspect whether the components (such as the subframe, support arm, suspension arm, steel wire rope, hook, cylinder support, boom seat, and fork, etc.) are damaged, deformed, or cracked, Whether or not the friction surface is roughened, burned, bitten or excessively worn, the problem is found to be dealt with promptly to prevent accidents during operation. Before operation, check the holding pressure performance of the lifting mechanism and try to avoid overload or partial load. Always keep the lubrication of each moving surface well. 70% of failures in the hydraulic system are caused by hydraulic oil, and 90% of failures caused by hydraulic oil are caused by foreign matter in the hydraulic oil. Therefore, it is necessary to prevent the hydraulic oil from being contaminated, ensure that it works at normal oil temperature, and ensure that the hydraulic device is in good condition. The hydraulic oil is inspected regularly and the hydraulic oil is changed and the hydraulic system is cleaned as required.
The maintenance in use is mainly reflected in the following aspects: When driving, the power take-off device must be separated and the vehicle must be decelerated when supporting the vehicle. The hydraulic oil should be suitable, clean, reliable, and regularly replaced and cannot be mixed. The difference between the pressure of the hydraulic system and the rated pressure should be kept within ±10%. Too high or too low will affect the normal operation of the hydraulic system. Always check the hydraulic system for leaks. If the hydraulic system needs to work for a long time, or when it is continuously operated in a high temperature environment, it must be noted that the temperature of the hydraulic oil must not exceed 60°C. Always check the sturdiness of the main bolts, especially the bolts of the pins. When the winch is operated, the wire rope on the winch must not be less than 5 turns, and the winch clutch control device cannot be touched when the wire rope is under load.
