Halligan bar

The Halligan tool is a special design of a crowbar. On a steel rod with a round or a hexagonal cross-section on the one side, two tool blades at an angle of 90 ° to the stem and 90 ° attached to each other, on the other hand a blade at an angle of about 30 ° to the stem or just outside the stem escape.

By this arrangement, each of the blades with a suitable impact tool ( in Germany is often a splitting maul, but also an ax, sledgehammer or a TNT tool used ) taken and are thus anchored sufficiently strong lever for subsequent applications.

Blade shapes

The first 90 ° blade is wedge-shaped. For example it may be beaten in narrow gaps, so as to expand it by the edge of the wedge forces.

The second 90 ° blade is hook-shaped with a pointed round mandrel. It is commonly used to create holes in thin sheet metal and soft materials.

The 30 ° blade has the iron nail shape ( crowbar, Geißfuß ). Alternative to the 30 ° blade a version with a metal cutting claw is available.

Naming

The term Halligan tool goes in the name of the inventor, Hugh Halligan, back. Halligan was First Deputy Fire Commissioner in the New York City Fire Department. He developed the tool end of the 1940s, the original weighed 8.5 pounds ( about 3.9 kilograms) and was forged from one piece.

Under the name protection of products, a variety of other labels are well known and conventional: Hooligan tool Haligan tool, per bar, Hallagan bar and more.

Accordingly, the products by length ( about 500 to 1500 mm ), material (steel, aluminum, non- zündfunkenreißende alloys, electrically non- conductive materials ) the compounds ( shrunk, jointed, forged from one piece ) and the design of the blades differ in detail.

Together with a tension strap can be formed, refer to both tools with a handle and carry with one hand to a splitting hammer or other striking tool a package.
