  • Patent number: 11583867
    Abstract: 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.

  • Publication number: 20210237096
    Abstract: A chipping device that has a chipper framework and a rotor having a plurality of spaced apart replaceable knives, teeth or strikers mounted on a periphery of the rotor and which cooperate with at least one anvil for comminuting desired limbs, branches or trunks of trees into chips having a desired size. A combustion engine supplies rotational drive to at least the rotor. A hydraulic power source for supplying power to hydraulic components of the chipping device and controlling operation thereof. Both the engine and the hydraulic power source being solely and entirely supported by the chipper framework so as to move along with the suspendable chipping device.
