摘要： A powered hammer includes a body in which is disposed a motor and a hammer mechanism driven by the motor when the motor is activated. A tool holder is coupled to a front portion of the body and which is capable of holding a cutting tool. The hammer mechanism, when driven by the motor, is capable of imparting impacts to a cutting tool, when held by the tool holder. A handle is moveably coupled to a rear portion of the body for movement toward and away from the body along a tool axis of the tool holder. The handle includes a grip portion and first and second end connection sections coupled to opposite end portions of the grip portion. The first and second end connection sections are slideably mounted on first and second arms that project rearward from the body. A movement control mechanism is mounted inside the handle and coupled to the first and second arms and the handle. The movement control mechanism is configured to ensure that the two end connection sections move toward and away from the body in unison to inhibit angular movement of the grip portion relative to the body. A damping element disposed between the handle and the body to reduce vibration transferred from the body to the rear handle.

摘要： The disclosure describes a handle assembly for a power tool that includes attachment means for attaching the assembly to a housing of a power tool. The handle means is adapted to be held by a user of the power tool and the handle means is mounted to the attachment means and is capable of limited movement relative to the housing of the power tool. The vibration damping means acts between said housing and said handle means. The vibration damping means can also comprise elastomeric material. The attachment means can be mounted in use to the housing via a bolt on one of the attachment means and the housing passing through a respective aperture in the other of said attachment means and the housing. At least some of the elastomeric material is arranged in use between at least one said bolt and a corresponding said aperture. The handle means can be pivotable and/or slidable relative to said attachment means. The vibration damping means can comprise at least one spring (e.g., compression/spring or torsion spring).

摘要： Dock leveler safety supports are disclosed herein. An example dock leveler disclosed herein includes a deck movable relative to a platform between a raised position and a lowered cross-traffic position when the dock leveler is in a working configuration. The deck to be inhibited from descending toward the lowered cross-traffic position when the dock leveler is in a service configuration. A first deck obstruction is movable relative to the deck between a secured position and an unrestrained position. The first deck obstruction in the secured position configures the dock leveler in the service configuration. The first deck obstruction in the unrestrained position configures the dock leveler in the working configuration. The first deck obstruction in the secured position to block movement of the deck toward the lowered cross-traffic position and the first deck obstruction in the unrestrained position to permit movement of the deck toward the lowered cross-traffic position. A first connector to couple the first deck obstruction to an obstruction actuator. The first connector including a rod, a sleeve to telescopically receive the rod, and a spring held in compression between the rod and the sleeve.

摘要： Dock leveler safety supports and related methods are disclosed. An example method includes raising a front end of a deck above a platform, where the front end is elongate in a lateral direction and the front end extends laterally between a first side and a second side of the deck. The method includes manually pulling a first deck obstruction in the lateral direction out from the first side so that the first deck obstruction extends out over a perimeter of the platform. The method further includes lowering the front edge of the deck until the first deck obstruction descends upon and engages the platform.

摘要： A dock leveler having safety supports includes a deck movable relative to a platform between a raised position and a lowered cross-traffic position when the dock leveler is in a working configuration, where a first lateral edge and a second lateral edge of the deck are proximate the platform when the deck is in the lowered cross-traffic position and the deck residing at least partially in a pit when the front edge of the deck is in the lowered cross-traffic position. A front edge of the deck is above at least one of the lowered cross-traffic position or the raised position and inhibited from descending toward the lowered cross-traffic position when the dock leveler is in a service configuration. A first deck obstruction is movable relative to a deck between a secured position and an unrestrained position, where the first deck obstruction in the secured position configures the dock leveler in the service configuration and the first deck obstruction in the unrestrained position configures the dock leveler in the working configuration. The first deck obstruction extends farther beyond the outer perimeter of the deck when the first deck obstruction is in the secured position than when the first deck obstruction is in the unrestrained position.

摘要： Restraints for restraining a vehicle at a loading dock are described. An example restraint described herein includes a brace movable between a holding position and a release position. A first portion of the brace engages a supporting portion of the vehicle and a second portion of the brace engages a non-movable location at the loading dock to restrain the vehicle relative to the loading dock when the brace is in the holding position. For the holding position, the first portion of the brace moves in one direction underneath the vehicle to engage the supporting portion and the second portion moves in a second direction underneath the vehicle to engage the non-movable location. The first and second portions retract to allow the vehicle to move relative to the loading dock when the brace is in the release position.

摘要： A wheel restraint includes a wheel chock that is manually movable between a retracted position clear of a wheel of a vehicle at a loading dock and an operative position to block the path of the wheel. In the retracted position, the chock can be manually moved freely along a track that is mounted to a driveway of the dock. When the chock is manually moved from its retracted position to its operative position, a locking feature automatically restricts the movement of the chock relative to the track. When the chock is manually moved back to its retracted position, the locking feature automatically disengages. Although the wheel chock is connected to a track, most of the force exerted by the wheel against the chock is transmitted directly from the chock to the driveway.
