CMU Cormach 180,000 E4 with a lifting capacity of 50 tons

The Cormach 180,000 E4 with a lifting capacity of 50 tons is a Z-shaped hydraulic lifting mechanism with an articulated or "cranked" boom with a rigid (hinged) suspension of the lifting body (hook, gripper, etc.) and an integrated winch for suspending the second lifting device, which is pivotally mounted on the boom head. The boom head of a heavy hydraulic crane is equipped with a rotator. In the folded position, the boom of the hydraulic telescopic crane is parked in the plane of the self-propelled cargo carrier. An additional platform is installed between the hydraulic manipulator and the cabin to accommodate the payload and accessories for the manipulator. The Cormach 180,000 E4 manipulator crane is a technical hydraulic drive device that simulates the functions of a human hand with the ability to telescope cargo and bring it to a height and lower the load below the carrier level due to the cable suspension of the hook. The boom of the manipulator has a payload of 50 tons at a reach of 2 meters, with a practical payload of 30 tons at a reach of 4 meters with a load moment of 156 tons / meter. The maximum reach of the boom is 12 meters, with a lifting capacity of 12 tons per boom. To stabilize the operation, the hydraulic manipulator is equipped with a 4-point support system due to 2 H-shaped outriggers.



The advantage of a heavy hydraulic manipulator with a payload of 50 tons on a self-propelled chassis over a telescopic crane lies in the possibility of creating a highly maneuverable and compact lifting vehicle. It is for such work that a GMP hydraulic crane of the CMU manipulator type has been created and is being used using a full-turn crane manufactured by Cormach with a maximum lifting capacity of more than 40 tons and a practical permissible lifting capacity on a hook of 25 tons at a reach of 6 meters. The lifting unit is mounted on a special ASTRA 88.45 8x8 wheeled chassis. The self-propelled chassis carrier of an 8x8 hydraulic crane with single–pitched hub drive wheels made it possible to obtain maneuverability and maneuverability characteristics that allow the hydraulic crane to operate in areas demanding such characteristics as crane mining, quarry work on mining equipment repairs, crane operation in tunnels, mining crane use, lifting operations in indoor conditions. production facilities, workshops, and construction sites. A hydraulic manipulator based on an off-road chassis can be used in mountainous conditions on serpentines, off-road for lifting power transmission lines, as a tool for evacuation and rescue. The standard power unit of the crane manipulator chassis is a serial diesel internal combustion engine manufactured by Iveco Cursor with a power of 330 kW or 450 hp. Automatic gearshift gearbox is an automatic hydromechanical ZF Ecomat 6HP902.
