A weight balancing gantry has a tower having a fixed length radial arm pivotally coupled from a pivot point at an upper end of the tower. An angle strut acts between the tower and the radial arm across the pivot point. A pivot point pulley is located at the upper end of the tower and a weight balancing mechanism located at the tower. A bogey runs along the radial arm and has a bogey pulley. A positioning mechanism at the radial arm has at least one controlled cylinder for positioning and holding the bogey along to the radial arm. A cable runs from the weight balancing mechanism, up across the pivot point pulley and over the bogey pulley to attach to an industrial tool.

A device for receiving a hand-held power tool is provided. The device can serve as an interface between the hand-held power tool and a support or carrying structure and comprises a first and a second fastening means and a counter structure. With the interface it is possible to optimally adapt the suspension of the hand-held power tool to the center of gravity of the hand-held power tool. In addition, the interface can be adapted to different hand-held power tools or types of hand-held power tools by an adjustable distance between the first fastening means and the counter structure or an adjustable diameter of the counter structure. In further aspects, the invention relates to the use of the interface for fastening a hand-held power tool to a support structure, and to a corresponding method.

A tool guide has a mounting, a lifting mechanism, and a chassis. The mounting is for fixing a hand-held machine tool. The mounting is mounted on the lifting mechanism. The lifting mechanism has a propulsion unit for vertically lifting the mounting. The chassis has two wheels on a wheel axle, a drive coupled with the wheels, and a steering system. The lifting mechanism is rigidly mounted on the chassis. A center of gravity sensor is arranged to detect a lateral deflection of the center of gravity of the lifting mechanism relative to the wheel axle. The steering system is configured to control the drive to deliver a torque counteracting the lateral deflection.

A lanyard comprises a wire-like element with two ends. A reel with a spring is provided with a rotor that is movable with respect to a stator in two directions of rotation. The wire-like element is fixed to the rotor to be wound or unwound. A clamp is fitted movable between a position where the clamp is at a distance from the textured contact area to allow rotation of the rotor and a position where the clamp is in contact with the textured contact area to prevent rotation of the rotor. The clamp is mounted movable with respect to the stator to move under the effect of its weight according to the incline of the stator with respect to the gravity vector to move the clamp between the two positions.

A balancer for tools includes a rotating winding and unwinding drum for a cable, configured with a free end for supporting a tool. The balancer also includes a spring, wound around the main axis of rotation of the drum and integral with a terminal portion with the drum, in order to generate an elastic reaction, as a consequence of the unwinding of the cable and of the consequent rotation of the drum, adapted to facilitate the rewinding of the cable. The balancer further includes an element for braking the drum, which is adapted to generate a resisting moment which acts even indirectly on the drum to contrast the rewinding stroke of the cable; a respective electronic unit is furthermore associated with the element and is provided with a module for the control and adjustment of the intensity of the resisting moment generated by the element.

A drill holder includes a base, an elongate support member extending substantially perpendicularly from the base, and an arm mounted to the support member. The arm extends substantially perpendicularly from the support member and is free to slide along at least a portion of the support member. The arm includes holding means for holding a drill and a weight.

A positionable tool support device is mounted near a work surface for supporting a tool for a user. The tool support device includes a surface mount to secure the tool support device to a support surface. A gravity-balancing articulated arm assembly is coupled to and extends from the surface mount. The gravity-balancing articulated arm assembly is selectively adjustable about both vertical and horizontal axes. A rigid support extension is coupled to the gravity-balancing articulated arm assembly for selective rotation relative to the gravity-balancing articulated arm assembly. A flexible tensile member is coupled to and extends, in a relaxed state, vertically downward from the rigid support extension. The tensile member is coupled to the tool.

A self-aligning tool guide has a holder for securing a portable power tool for working on a ceiling, a lifting mechanism, and a self-balancing chassis. The holder is mounted on the lifting mechanism. The lifting mechanism has a propulsion system for raising the holder parallel to a lifting axis. The self-balancing chassis has two wheels on a wheel axis, a drive coupled to the two wheels, and a steering system. A contact sensor serves for detecting an indirect contact of the holder with the ceiling. The chassis has a brake. A controller has a mode in which the brake is activated and the balancing of the self-balancing chassis is deactivated.

An industrial device including a portable tool and a support for this tool. The tool is provided with a motor driving a mechanism in rotation, an electrical energy store to power the tool during operation and a controller to control the motor. The support includes a line, one extremity of which is affixed to the tool, a receiving element defining a location for the grasping of the tool and a winding apparatus of said line exerting a vertical tension to the tool so as to lighten its weight when it is no longer at its grasping location. The industrial device further includes a transmission of an electrical energy to charge the energy store when the tool is positioned in the receiving element. The tool is light weight tool while at the same time highly maneuverable in charging supercapacitors or a battery only when the tool is on the support.

According to an embodiment, a work support device includes a measurement unit and an irradiation control unit. The measurement unit measures an in-passage structure of a passage inside of which a user can work. The irradiation control unit controls an irradiation unit to emit light indicative of a work region to a corrected work position obtained by correcting work position information set based on a predetermined designed in-passage structure indicative of an ideal structure in the passage by using a result of the measurement by the measurement unit.
