Vehicle rescue tips (tools and equipment) hydraulic cutting pliers

Usually this is the most important tool. The hydraulic cutting pliers can handle the latest vehicle structure because it has a wider blade opening and is very suitable for handling modern cars with larger profiles.

Shear performance depends on the following key factors:

1 , the tool structure

Create quality (lightweight and ergonomic) and design features such as LED lights

2 , blade design

Blade shape and geometry ensure optimal shear performance

3 , cylinder capacity

Cylinder size affects shear capacity

4 , the center bolt structure

Bolt construction reduces blade pitch and improves shear performance

The most common uses of hydraulic cutting pliers are:

1. Cut A- pillars, B- pillars, and C- pillars to remove the roof

2, manufacturing safety cutout, for example, in column A slam after manufacturing security incisions rollover

3 , cutting the outer wall board, do the third door

4 , cut the rear door

5 , cut seat back

Cut type

Generally two types of cut

1 , around the cut

The blade completely surrounds the material to be cut, such as A column

2 , piercing cut

The blade penetrates the material to be cut, such as a wide C- pillar

Effective use of skills

1 , do not work inside the tool (for example, let yourself in the middle of tools and vehicles)

2. Always remove the interior vehicle trim before performing any shears, which allows the operator to identify hardened materials (such as seat belt anchor bolts) and airbag / airbag parts (such as inflators). Do not cut without exposure.

3. The cutting pliers have the maximum theoretical shear force at the incision of the blade. Therefore, completely surrounding the material to be cut can ensure the best effect.

4. When circumventing or penetrating shearing, the separation or intersection of the blade tip is always monitored.

5. If possible, cut at 90 degrees. This will be more efficient. For example when cutting a B- pillar, this gives the operator more work space.

6. Use the safety handle to control the cutting speed.
