The ore gantries are equipped with a grab and they are intended for bulk cargoes handling, including sintered iron ore, coke, iron-ore pellets and coal. The ore gantries have the increased lifting capacity, bigger hoisting height (in some cases up to 50 meters), sufficiently increased trolley speed and span length up to 120 meters. Depending on handling operations specifics, the ore gantry can be equipped with a rope bucket grab, a removable electromechanical (electro-hydraulic) grab.

The mine bridge crane rests on four balance trucks and moves on crane ways, laid on ledges of a wall upper part or of a column. The mine crane has no trolley, that’s why all the mechanisms are located directly on the crane bridge. For crane work in the shaft, ways, preventing swinging of the traverse, are mounted. The traverse is intended for equipment lowing and lifting and allows placing maintenance staff for inspection of the air shaft. On the mine crane traverse there are video cameras for inspections of the mine, for cargo stop on the definite gateroad (floor) there is a controller on which there is an absolute rotation sensor, which quantifies wound or unwound rope by number of drum revolutions.

The rotary wagon tipplers of VRS-93 type have a rotor rotated on 175 degrees about the longitudinal axis. The unloading is performed into an underground receiving bin. The wagon tippler should operate together with an electric trolley-pusher and a positioner.

The side wagon tippler of VBS type consists of two shaped rotors, mounted on a shaft, two cradles with two platforms, suspended on rods, two electric drives and four support pillars with bearings. Partial static balancing of the whole system about the axis of rotation is achieved by installing a counterweight.

The scraper reclaimer refers to scraper unloaders and is intended for bulk materials stockpile dismantling. The scraper reclaimer is used for continuous download flow onto a stockyard conveyor.

The boom bucket-wheel stacker and reclaimer is intended for coal or other bulk material stockpiling and its reclaiming from a stockpile. The stacker and reclaimer travels on rail track, placed along a storage conveyor. The conveyor on the boom is reversible and it transfers material either from a storage conveyor to a stockpile or from the reclaiming rotor to a storage conveyor. The machine is intended for open stockyard operations.

The universal and effective method of bulk materials storing is to form a smooth and continuous ridge of material that extends along the entire length of stockyard and has predetermined height. The stacker is a conveyor-type belt stacking machine, intended for taking and stockpiling breakstone, sand, clay, limestone, ore, coal, gravel and other types of bulk materials.

The bridge-type bucket-wheel reclaimer is intended for reclaiming coal or other dry bulk material from a stockpile. It moves on rail tracks, located along a storage conveyor. It is usually applied at open homogenization stockyards.

The stacker is intended for material taking from a conveyor for following forming radial coal storage of a mine. Material feeding on a conveyor is carried out through a transfer bin, which consists of an external conveyor and lining of wear-resistant steel. Material unloading is carried out by free flow through a discharge unit.
