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.

A wearable manufacturing assistance device (1) for supporting a manufacturing tool (3), the manufacturing assistance device (1) includes a body unit (7) including a fastener (11) for fastening the body unit (7) to the back (13) of a technician (5) in a wearing position (15), and an arm member (9) which has an attachment end (19) attached to the body unit (7) and a tool end (21) opposite to the attachment end (19), wherein at the tool end (21) a mounting device (23) for mounting the manufacturing tool (3) to the arm member (9) is provided. While the wearable manufacturing assistance device (1) is fastened to the back (13) of the technician (5) and is in a wearing position (15), the arm member (9) extends from the attachment end (19) at the body unit (7) over a shoulder (17) and laterally past a head (27) of the technician (5).

A tool positioner for a chipping or drilling tool having a tool axis. The positioner has a frame, a tool support configured for coupling the chipping or drilling tool to the positioner and mounted to the frame via a first joint having a first pivot axis and a second joint having a second pivot axis, the first pivot axis, the second pivot axis and the tool axis intersecting each other at a common point. The first joint and the second joint allow angular movements of the chipping or drilling tool at least about the respective first pivot axis and the second pivot axis. The tool support is further displaceable relative to the frame to enable a plurality of degrees of freedom in translation of the tool support. An automated locking system is operable to restrict and allow the plurality of degrees of freedom in translation of the tool support.

The present invention provides a foldable demolition hammer trolley designed for floor removal operations. It comprises a first frame with a main rod, a moving assembly, and a pedal assembly. The moving assembly, located at the main rod's bottom end, includes a fixed axle and wheels. One side of a connecting part of the pedal assembly connects pivotally to the fixed axle and the other side is fixedly to a pedal pad. The second frame is pivotally attached to the first frame and includes a support frame part, a carrying frame part, a telescopic sleeve rod, an adjustment member, and first and second fixing assemblies. The support and carrying frame parts are pivotally connected. The telescopic sleeve rod and adjustment member between them allow distance adjustment. The fixing assemblies secure the demolition hammer's handle and body. This can reduce the force required by the operator.
