Hammer Mechanism For Air Impact Wrenches

Single Hammer

Single hammer mechanism provides one blow per revolution. This means greater hitting power, longer life and easy maintenance. This type of mechanism is recommended for medium duty use.

Pin Clutch

The Pin Clutch type hammer mechanism has a rotating mechanism in which the round hammer pins move up and down, engaging the anvil shank and producing a powerful impact. Although the clutch assembly is smaller and lighter than other mechanism assemblies, it produces higher torque with minimum vibrations.

Twin Hammer

This hammer mechanism has two identical hammers that delivers an instantaneous balanced blow, reducing vibration and transferring more torque to drive the anvil shank than any other mechanism. This design is the most durable and is excellent for use in heavy industrial applications.

Two Hammer

This design is simmilar in operation to the single hammer mechanism except it has two counter balanced hammers which hit twice per revolution resulting in less vibrations causing less operator fatigue.
