A wallboard removal tool includes a shaft extending between an inner end and an outer end. An outer wallboard support is movably coupled to the shaft. An inner wallboard support is movably coupled to the shaft. The inner wallboard support is provided at the inner end. The inner wallboard support is configured to engage an interior surface of a wallboard and the outer wallboard support is configured to engage an exterior surface of the wallboard to capture the wallboard therebetween. The wallboard removal tool is shaken to free the wallboard from fasteners holding the wallboard to studs of the wall.

A prying tool includes a prying end with a first prying member and a second prying member pivotally engaged with a main body of the prying tool. The first and the second prying members are pivotal toward and away from each other. The first prying member has a first claw and the second prying member has a second claw respectively. The first and the second prying members are pivotal between a first configuration in which first and the second claws are adjacent to each other and a second configuration in which the first and the second claws are away from each other.

A concrete/steel structure disassembling apparatus which comprises a triangular or T-shaped housing, and a suspension member is pivotably coupled to the triangular or T-shaped housing, and the suspension facilitates suspension of the triangular or T-shaped housing from a crane. At least a concrete/steel pulverizer apparatus is pivotably supported by the triangular or T-shaped housing, and the concrete/steel pulverizer apparatus comprises a pair of concrete/steel pulverizer arms for engaging with a desired section of a concrete/steel structure and pulverizing the same. The concrete/steel structure disassembling apparatus incorporates its own completely independent power module for supplying hydraulic power to the concrete/steel pulverizer apparatus and controlling operation of the at least one pair of concrete/steel pulverizer arms, and the power module is supported by the triangular or T-shaped housing.

The present disclosure relates to a blasting system, the blasting system including: a drilling device configured to form blasting holes on a blasting target on the basis of a blasting design map; a charging device configured to place explosives in the blasting holes; detonators configured to detonate the explosives; a central control unit configured to confirm a position of a worker in real time, the worker driving the detonators; and a worker terminal configured to transmit worker position information to the central control unit, the worker position information indicating the worker position. The blasting system of the present disclosure can automatically connect the detonator to the central control unit, and improve worker convenience of the blasting work.

The invention relates to a demolition robot (1), comprising a cable (12) intended to be connected to an electric network to power a motor (21), a pump (22) that is powered by the electric motor for generating a hydraulic flow to consumers (13), wherein the motor (21) is activable at varying thermal load values (PT), depending on the current consumer's (13) need for hydraulic power, a control unit (24) arranged to receive information about the thermal load (PT) on the motor, to determine a partial thermal damage value (SL, SM, SH) at various thermal loads (PT) on the motor. To minimize the risk of thermal damage to the motor, the control unit (24) is adapted to compare said partial thermal damage values (SL, SM, SH) with a normative partial thermal damage (A) and is adapted to limit the thermal load (PT) on the motor (21) to a maximum allowable thermal load value (PTmax), if the partial thermal damage value (SL, SM, SH) exceeds the normative partial thermal damage (A) at a predetermined value (A′).

A work machine is capable of rotating an attachment while appropriately supporting a load applied to the attachment. The work machine has a hydraulic cylinder attached to a body side surface of an arm and a first link rod extending along a back side surface of the arm. A second link rod is rotatably supported via a first pin extending in the width direction of a front working device, and has one end projecting toward the back side surface of the arm and the other end projecting toward the body side surface thereof. One end of the first link rod is rotatably connected to the attachment. One end of the second link rod is rotatably connected to the other end of the first link rod, and the other end thereof is rotatably connected to a distal end of a cylinder rod of the hydraulic cylinder via a third pin.
