Operation Guide Of Fire Hydraulic Tongs In Large Fire Rescue

1. Basic structure and function of fire hydraulic pliers

Fire hydraulic pliers are mainly composed of hydraulic pump, cutting pliers head, control valve and oil pipe. Its working principle is to use the power provided by the hydraulic pump to generate huge shear force on the pliers head, thereby cutting or breaking hard metal or other materials. The pliers head of fire hydraulic pliers is generally made of high-strength alloy steel, with extremely strong cutting ability, and can cope with materials such as vehicles, building frames, and steel bars.

 

2. Application scenarios of fire hydraulic pliers in large-scale fire rescue

Car accident rescue

At the scene of the fire, the vehicle may be damaged by explosion or fire, and the trapped people may be stuck in the deformed car. Fire hydraulic pliers can quickly cut the metal, steel bars and structural parts of the car body to provide rescue space for the trapped people.

 

Building collapse rescue

During a fire, the building may collapse or partially collapse, crushing the trapped people. Fire hydraulic pliers can effectively cut the steel bars, pipes, metal frames, etc. in the building to open a passage for rescuers.

 

Clearing obstacles

There are often a large number of obstacles at the fire scene, such as collapsed walls, door and window frames, and wires and cables. Fire hydraulic pliers can quickly clear these obstacles, open up channels, and help trapped people escape.

 

3. Operation steps of fire hydraulic pliers

Equipment inspection and preparation

Before using fire hydraulic pliers, first check the equipment. Confirm the integrity of the hydraulic pump, oil pipe, pliers head and other components, ensure that the hydraulic oil is sufficient and the pump pressure is normal. Check the sealing of the hydraulic system to ensure that there is no oil leakage. After the inspection, prepare the hydraulic pliers and power supply to ensure the normal operation of the equipment.

 

Select the cutting part

In fire rescue, it is crucial to choose the correct cutting part. Rescuers need to evaluate the best cutting point based on the on-site conditions. Common cutting parts include car doors, window frames, steel structures of buildings, and collapsed metal parts. When cutting, try to avoid cutting the area where the trapped people are located to prevent secondary injuries.

 

Hydraulic pliers head operation

Start the hydraulic pump and adjust the pressure to the appropriate working range. When using hydraulic pliers, make sure that the pliers head firmly clamps the object to be cut. Apply pressure slowly and control the cutting force through the hydraulic pump until the object is completely cut or pried open. The pressure should be adjusted in time according to the material thickness and hardness of the object to avoid excessive use of the hydraulic pump to cause equipment damage.

 

Collaborative work

Fire rescue usually requires multiple people to work together to ensure cooperation and coordination between various rescue teams. The person operating the fire hydraulic pliers should keep in touch with other rescue team members to ensure the efficient execution of the rescue mission. In some cases, multiple people may need to cooperate with different rescue tools to complete complex rescue work together.

 

Pay attention to safety when cutting

When using fire hydraulic pliers, rescuers need to wear protective equipment, such as fireproof clothing, gloves, goggles, etc., to avoid being injured by flying metal fragments or high-temperature flames. During the cutting process, avoid touching the hydraulic pliers head with your hands or other parts, keep the tool stable and ensure safety.

 

4. Advantages of fire hydraulic pliers in fire rescue

High efficiency

Fire hydraulic pliers can cut and expand quickly, greatly improving the efficiency of rescue. In complex and urgent fire rescue, it can quickly open the doors, windows or building structures to create survival space for trapped people.

 

Adaptable to a variety of materials

Fire hydraulic pliers have strong cutting capabilities and can easily cut different materials such as steel bars, metals, wood, etc., and are widely used in a variety of rescue scenarios.

 

Easy to operate

The operation of fire hydraulic pliers is relatively simple. Even in limited time and space, rescuers can complete the cutting task through simple operations, which improves the rescue efficiency.

 

Stability

Hydraulic tools do not rely on batteries or gas sources, and can stably provide sufficient power support, especially when the power supply is insufficient or the gas source is unreliable, hydraulic pliers can still play a powerful role.
