The present invention relates to a versatile nail magazine for a nailing gun. In certain embodiments, the versatile nail magazine includes an elongated nail magazine body for loading nails. The nail magazine body includes: a front end connected to a nailing head of the nailing gun, and a rear end for reloading various types of nails, a nail shank track having a lower end, and an upper end, a nail head track disposed on the upper end of the nail shank track, and one or more nail head positioning protrusions disposed between the upper end of the nail shank track and the nail head track for securing the plurality of nails. The nail shank track, and the nail head track extend lengthwise along nail magazine body. Nails in a nail strip are loaded in the nail head track, and the nail shank track from rear end of nail magazine body.

Positive feed tools that include gear heads configured to be driven by a motor. The gear heads further include a pneumatic manifold that provides for access to input/output signals to add on additional components that include additional air logic functionality. The gear head includes first and second interface positions. Each interface is configured to receive either the motor for powering the gear head or an add-on component to provide additional functionality to the tool.

A damping system for a hydraulic hammer is disclosed. The hydraulic hammer includes a housing and a mounting bracket disposed on the housing. The damping system includes an expandable bladder positioned between the power cell and the mounting bracket. The expandable bladder is configured to receive a supply of pressurized fluid and store a threshold volume of pressurized fluid therein. The damping system includes a plurality of sensors for detecting one or more parameters related to operating conditions of the hydraulic hammer. The damping system includes a controller disposed in communication with the sensors. The controller is configured to receive one or more inputs indicative of the parameters from the sensors to determine a threshold volume of pressurized fluid to be maintained in the expandable bladder. The controller is configured to supply the threshold volume of pressurized fluid to the expandable bladder during an operation of the hydraulic hammer.

A pressure indicator for a hydraulic hammer is provided. The pressure indicator includes a sleeve member configured to couple to an opening defined in a wall housing of an accumulator of the hydraulic hammer. The pressure indicator further includes a plunger slidably disposed within the sleeve member and movable between a first position and a second position with respect to the sleeve member. The plunger includes a first end disposed outside the wall housing of the accumulator. The plunger further includes a flange coupled to a second end. The pressure indicator further includes an elastic member inserted over the plunger and disposed between the wall housing of the accumulator and the flange. A position of the first end of the plunger with reference to an outer end of the sleeve member provides a visual indication of the pressure of the gas within the accumulator.

A machine tool is disclosed. The machine tool has a tool receptacle for receiving a tool on a working axis, a housing, and a striking mechanism. An impact stop is provided for a beater or an intermediate beater. An impact absorber has two polymer-based absorber rings that are offset axially to one another and are disposed so that they overlap radially and has two iron-based disks disposed axially between the absorber rings.

A buffer system for a hydraulic hammer is disclosed. The buffer system includes a wear member disposed between a first component and a second component. The wear member includes a first surface. The first surface is adapted to abut an inner surface of the first component. The wear member also includes a second surface distal to the first surface. The second surface is adapted to abut an outer surface of the second component. The buffer system also includes an insert member disposed in the wear member between the first surface and the second surface thereof. The insert member provides a visual indication when a predefined thickness of the wear member between the first surface and the second surface is worn.
