How To Choose a Suitable Rescue Hydraulic Cutter？

In emergency rescue, hydraulic cutters are indispensable tools, especially in emergency situations such as car accident rescue, building collapse, firefighting and demolition, which can quickly cut obstacles such as metal and steel bars to improve rescue efficiency. However, facing the various types of hydraulic cutters on the market, how to choose the most suitable model and specifications? This article will analyze the key factors for choosing a rescue hydraulic cutter in detail from the aspects of cutting capacity, power source, portability, safety performance, etc.

 

Understand the main types of rescue hydraulic cutters

Hydraulic cutters mainly use high-pressure hydraulic systems to drive blades or saw blades to cut metal or other hard materials with strong shearing force. Common types include:

Scissor-type hydraulic cutter

Features: Scissor-shaped blade, suitable for cutting steel bars, door frames, metal pipes, etc.

Applicable scenarios: traffic accident rescue, firefighting and demolition, building rescue.

Circular saw hydraulic cutter

Features: It uses a rotating circular saw blade, which is suitable for cutting thick metal plates, vehicle frames, etc.

Applicable scenarios: building collapse rescue, large equipment disassembly, and complex demolition tasks

Chainsaw hydraulic cutting machine

Features: Similar to electric saws, suitable for cutting wood, concrete and some metals.

Applicable scenarios: firefighting, forest rescue, earthquake rescue, etc.

 

Key factors for choosing rescue hydraulic cutting machine

1. Cutting capacity

Cutting force: Different models of hydraulic cutting machines have different cutting capacities, generally measured by "cutting force (kN)" or "maximum shear diameter (mm)". For car accident rescue, it is recommended to choose equipment that can cut steel plates with a thickness of more than 5mm or steel bars with a diameter of more than 20mm.

Applicable materials: Ensure that the hydraulic cutting machine can cut common materials at the rescue site, such as high-strength steel, aluminum alloy, vehicle frame, etc.

2. Power source

Manual hydraulic cutting machine: suitable for environments without power supply or small space, with simple structure but slow cutting speed.

Electric hydraulic cutting machine: powerful, suitable for high-intensity rescue tasks, but requires an external power supply.

Internal combustion engine driven hydraulic cutting machine: no external power supply is required, suitable for field or no power environment, but large in size.

3. Portability

Weight: Rescue missions require light tools. It is recommended to choose a portable cutter weighing no more than 20kg for quick deployment and operation.

Structural design: Ergonomically designed handles and models that can be operated by one person are more suitable for emergency rescue.

4. Safety performance

Anti-slip handle: Maintain a good grip in slippery environments and reduce the risk of misoperation.

Protective cover: Prevent cutting debris from splashing and improve safety of use.

Overload protection: Prevent overload from causing equipment damage or failure.

5. Reliability and maintenance

Brand quality: Choose well-known rescue equipment manufacturers such as Holmatro, Lukas, Hurst, etc. to ensure equipment reliability.

Easy to maintain: Check whether the equipment is easy to replace blades and maintain the hydraulic system to reduce the cost of use.

 

Selection of cutters for different rescue scenarios

1. Traffic accident rescue

Recommended tool: Scissor-type hydraulic cutter.

Reason: It can quickly cut off car doors, roofs, and seat brackets to facilitate the rescue of trapped people.

2. Building collapse rescue

Recommended tools: Circular saw hydraulic cutter.

Reason: Suitable for cutting reinforced concrete and metal frames to help open rescue channels.

3. Firefighting demolition

Recommended tools: Chain saw hydraulic cutter or scissor cutter.

Reason: Chain saw can cut wood and some metals, and scissor type is suitable for breaking doors and windows.

IV. How to use rescue hydraulic cutter correctly

Check the equipment: Check the blade wear and hydraulic oil status before each use to ensure the normal operation of the equipment.

Wear protective equipment: Use protective gloves, goggles, etc. to prevent damage caused by splashing debris.

Choose the right cutting angle: Avoid uneven force on the blade, resulting in breakage or jamming.

Avoid overload cutting: Operate according to the equipment parameters to prevent damage to the equipment or affect the rescue efficiency.

 

Conclusion

Choosing a suitable rescue hydraulic cutter can not only improve the rescue efficiency, but also ensure the safety of the operator. When purchasing, you need to focus on cutting capacity, power source, portability and safety performance, and choose the right equipment according to different rescue scenarios. Proper combination of hydraulic tools will help complete rescue tasks faster and safer.
