Auto Extrication Tools

Auto Extrication Tools

Emergency extrication tools and equipment have come a long way since the days of old. Simple axes and pry bars have given way to sophisticated hydraulically-operated machines that provide super-strength pressure for cutting, lifting, pulling and spreading. The "jaws of life" tool is a popular addition to law enforcement and firefighting agencies all over the world, because of its innovative design and life-saving capabilities. Strong hydraulic shears and cutoff saws have taken the place of hand-cutters and hand saws.

Hydraulic Spreaders

    Dedicated hydraulic spreaders use tremendous pressure strength to spread or open up crushed, confined areas. Typically made of high-strength low-alloy steel, they surpass strength indices of regular carbon steel. They come with interchangeable tips for a variety of rescue applications. Sturdy and resistant to impact and hydraulic line failure, they are used often by firefighting and law enforcement agencies. They can be powered by gasoline operated generators or portable battery packs that facilitate quick transport into remote areas. Some spreaders can exert over 50,000 lb. of pressure.

Hydraulic Cutters

    Hydraulic cutters come in a variety of shapes, sizes and weights, but their primary function consists of slicing through automotive door panels and solid steel frames with speed, efficiency and safety. They have wide-jaw interchangeable cutting blades with gaps available up to 8 inches and more. Hand-held, with 360-degree rotating heads, they are capable of fitting into tight areas and cutting through any thickness of solid steel automotive frames or uni-body components. They can exert up to 100,000 lb. of pressure.

Lifting Bags

    Lifting bags, sometimes called air jacks, are used for their strength and portability. Typically made of neoprene with Kevlar reinforcing, they perform best when wedged between obstructions or when used to lift extremely heavy objects, like overturned cars or trucks. They use high-pressure air produced by electric or gasoline powered generators.

    Carrying Case? No

    Model Info High pressure pneumatic lifting bag. Dimensions: 908x908 mm. Working pressure: 8 bar. Max. inflation height: 520 mm. Max. effective lifting force: 670 / 68 kN / t.

Rams

    Hydraulic ram jacks have long cylindrical tubes through which hydraulic oil is forced under pressure to exert pressure on a piston. The piston shoves a telescoping rod out to force objects apart. Ram jacks can be fitted into tight areas, typically areas wider than hydraulic spreader's reach. They work well when used to pry seats away from dash boards or lift crushed roofs to gain access to trapped to crash victims.

Generator Pumps

    Generator pumps drive the hydraulic extrication tools by forcing hydraulic oil into the mechanisms, activating the arms, blades, pistons or jaws. They can run two heavy-duty hydraulic extrication tools at the same time, delivering a steady high-pressure flow. They come in electric or gasoline generator versions. Smaller, portable versions can be carried via backpack into remote locations where rough terrain impedes moving larger equipment.

Saws

    Driving while intoxicated can cause severe accidents where extrication tools are needed.

    Hand-held gasoline operated cutoff saws demonstrate their versatility when large holes must be cut into door or roof panels. They look like a sideways hand-held skill saw and use highly abrasive cutting disks to cut through rubber, metal, fabric and concrete.
