摘要： 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.

摘要： A powered tile breaker has an adjustable frame and the frame is further comprised of a handlebar member, a foldable shaft, a base member, and wheels. The base member holds a chiseling assembly which comprises a main electric motor located inside a motor casing. The motor powers a chisel member. The chiseling assembly is angularly adjustable by way of an actuator member which consists in a secondary electric motor driving a piston. The piston has one end rotationally connected to the base member, and the actuator member is rotationally connected to a lever member which extends from the chiseling assembly and which connects at a pivot point.

摘要： An apparatus for supporting conventional hand-held pneumatic breakers in such a way as to break a concrete slab down to the desired precise depth. The slab can be a building floor, bridge deck, or other slab required to be broken to a predetermined depth. The apparatus comprises a mounting frame adapted to replace the bucket of a mini-loader such that the mounting frame can be positioned at an adjusted level and orientation by the hydraulically operated arms and rams of the mini-loader. The mounting frame has an upper flange from which depend U-shaped guiding brackets between which are guided the transverse handlebar of each breaker. A guide for each drill bit of the breakers is fixed to the mounting frame. The breakers are free to move between a top and a lower limit position relative to the mounting frame. In the lower position the handle bars are supported by the bight of the U-shaped brackets. During the concrete slab breaking work, the drill bit abuts on the slab solely under the bias of the hammer weight; this results in precise drilling.

摘要： Apparatus including a downwardly-extending breaker bar connected for vertical movement by linkage to a base adapted to be mounted on a suitable traction unit. A hydraulic cylinder unit extends between the base and the breaker bar, and operating means is associated with the cylinder unit for selectively supplying fluid to said unit alternatively to raise and lower the breaker bar to cause it to strike a surface to be broken, such as the crust that forms on aluminum smelt in pots during the electrolytic production of aluminum.

摘要： A crust breaking machine includes a self-propelled carriage having front wheels and rear wheels, a crust-breaking tool of the continuously breaking type mounted on the carriage, and an arm provided on the carriage and adapted to support the tool. This arm is mounted for swinging movement in the vertical plane and in the horizontal plane, with a mounting located between the front and rear wheels and in front of the driver's seat seen in the normal driving direction of the machine during crust-breaking. Thus the tool can be brought into a working position on each side of the carriage and into a rest position in front of the carriage.

摘要： 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 and a drive coupled to the two wheels. A sensor serves for detecting a contact pressure of the holder, the contact pressure acting in the direction of gravitational force. The control station activates the propulsion system depending on the detected contact pressure.

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.
