Application Examples Of Rescue Hydraulic Tools In Highway Accidents

Highways are important traffic arteries for vehicles to travel at high speeds, but due to the high speed and large traffic volume, once an accident occurs, it often causes serious casualties and traffic jams. Rescue hydraulic tools have become important equipment in highway rescue operations with their powerful shearing, expansion and demolition capabilities. This article will introduce the main types of rescue hydraulic tools and analyze their key role in highway accident rescue through specific application examples.

 

1. Challenges of highway accident rescue

In highway accident rescue, rescuers face many challenges, including:

Complex accident scene

Vehicles may be severely deformed after high-speed collisions, and ordinary tools are difficult to effectively demolish.

Multi-vehicle chain collisions may cause chaos at the scene and increase the difficulty of rescue.

Time is tight

The injured may be trapped in the car, and delaying rescue will increase the risk of secondary injuries.

Highway traffic pressure is high, and the accident scene must be cleaned up quickly to resume traffic.

High safety risks

There may be dangerous situations such as fuel leakage and electrical short circuits, which increase the difficulty of rescue.

The environment at the accident site is harsh, and rescuers need to use efficient and safe tools.

In such a situation, rescue hydraulic tools have become important equipment for firefighters, traffic police, and emergency rescue personnel.

 

2. Common types of rescue hydraulic tools

Hydraulic shears

Mainly used to cut metal structures such as car doors, roofs, and body pillars to open escape routes.

With strong shearing force, it can quickly cut high-strength materials such as car body steel plates, railings, etc.

Hydraulic expanders

Create rescue space for the injured by expanding or prying the deformed car body.

Applicable to breaking open car doors, expanding damaged car body structures, and helping rescuers enter the car.

Hydraulic top supporter

Can be used to support the car body to prevent secondary collapse.

Exerting force in a small space helps to expand the demolition space.

Hydraulic demolition tools

Combined with shearing, expansion, and top support functions, obstacles can be quickly demolished to improve rescue efficiency.

Some tools can be used underwater, in high temperature and low temperature environments, and are suitable for various accident scenarios.

 

3. Analysis of highway accident rescue examples

Example 1: Highway rear-end collision rescue

Accident situation:

On a highway, a large truck crashed into a small car in front due to insufficient braking, causing the car to be severely deformed, the driver was trapped in the car, and the door could not be opened.

Rescue process:

Evaluation of the scene

Rescuers arrived quickly and first checked the condition of the vehicle to ensure that there was no risk of fuel leakage or fire.

Using hydraulic shears to cut the door hinges

Because the door was severely deformed and could not be opened normally, the rescuers used hydraulic shears to cut the door hinges and remove the door.

Using hydraulic expanders to expand the rescue space

After cutting the door, the driver's seat was still severely squeezed. The rescuers used hydraulic expanders to prop up the car body to create enough escape space for the driver.

Successful rescue of the injured

After about 5 minutes of operation, the rescuers successfully rescued the driver and handed him over to medical staff for first aid.

 

Example 2: Highway rollover accident rescue

Accident situation:

A truck loaded with goods overturned on the highway due to a tire blowout. The driver was trapped in the car and the door was deformed due to the impact and could not be opened.

Rescue process:

Safety assessment

Confirm that the vehicle has no risk of secondary sliding, and arrange safety warnings around the truck.

Use hydraulic jacks to stabilize the vehicle body

Prevent the vehicle from tipping over again to ensure the safety of rescuers and trapped people.

Use hydraulic shears to cut the windshield

Due to the serious damage to the door caused by the rollover, the rescuers chose to break it from the windshield and use hydraulic shears to quickly cut the glass frame.

Use hydraulic expanders to expand the cockpit space

Expand the damaged vehicle structure so that the driver can be rescued smoothly.

Successful rescue

After 10 minutes of rescue operation, the driver was successfully rescued and sent to the hospital for treatment.
