Megalift
Hydraulic transport beam MEGALIFT is a device for lifting, manipulating and transporting loads on a single track suspended railway of profile I155 in horizontal plane and at inclination up to 30°. As a traction means and the source of oil pressure, it is recommended to use suspended locomotive of approved type.
Hydraulic transport beam MEGALIFT can be applied in underground workings of non-methane and methane mining plants qualified to ‘a’, ‘b’ or ‘c’ level of methane explosion hazard and class ‘A’ or ‘B’ of coal dust explosion hazard.
Hydraulic transport beam MEGALIFT consists of two transporting units connected with a connecting rod. Its construction consists of a frame (body) that is equipped with hydraulic actuator with hydraulic lock and choke valve for releasing. The frame is suspended on carrying trolley with the use of special carrier. Lifting chains are put into motion by simple chain transmission with loose shifting chain wheel. One end of the chain is anchored to the carrier and the other movable end can be connected to a cross-bar equipped with holes for fixing connecting rods with hooks for lifting loads. Both transporting devices are controlled using a distributor located on a link between MEGALIFT beam and the traction unit of the set.
