Transport containers – Skips
Skips are produced as spare parts for existing mining equipment in operation, or as new ones with upgraded parameters according to the operator’s request. They are dimensionally adapted to the given profile of the pit, and the construction to the specified technical parameters: useful load capacity, suspension of pulling and leveling ropes and equipment, etc. Skip from all-welded construction consists of a head, container and foot. The head is formed by a rigid frame with holes for rope suspensions, which is connected to the longitudinal rods of the frame. The fronts of the head are equipped with fixed guides, above them there are fixed brackets for mounting the sprung wheel guide. The upper part, lined with trench sheet, forms the floor for inspections and maintenance work. The container consists of a frame structure made of supporting longitudinal rods, covered with sheet metal, reinforced with crossbars against bulging. In the upper part from the front there is a loading opening, in the lower part there is an inclined chute and a discharge opening, closed with a guillotine or segmental rotary cap. The inclined chute and its sides are lined with wear plates, a relief canopy is placed above the cap. On the foreheads in the center there are medium fixed guides. Under the chute, a closed space for the transport of people, equipped with a door, is created at the bottom. The heel consists of a compact frame on which the supporting longitudinal rods terminate. On the fronts of the lower part there are brackets for wheel guides and fixed guides, and in the middle part there are beams for attaching the hinges of the lower leveling ropes.

Transport containers – Mining cages
Mining cages are used for the transport of rubble, people and material in pits and staple pits in coal and ore mines. According to use and design, they are divided into emergency cages, staple pit cages and two-story to four-story mining cages.
They are operated in the intake or exhaust pits of mines, they are mainly constructed as two-story to four-story, which can be in one piece or divided for easier installation in the mining pit. For the transport of rubble or material to the mine, they are usually made for two JDV type cars in a row behind each other. The suspension of the cages is mainly on one pulling rope. The cages are designed as welded structures – a supporting frame with a head and a floor, fixed or extendable floors of the other floors, fixed side plating. The equipment of the head includes rope hangers, a catch device and a fixed guide of the cage along the guide. On the head, there is a wheel guide on the front sides, an enclosure with a trench sheet and a railing with a canopy. The floors are equipped with rails and an arresting device for mine cars, possibly a beam for a rope groove or the transport of loads, holders and doors for the transport of people. In the case of a mining machine with a friction disc, the floor is supplemented with leveling rope suspensions. On its lower part, wheel guides of the cage and fixed guides are again mounted on the fronts.
Staple pits cages
These cages are used to transport people and material in blind mine pits to the mine floors, inaccessible by the main pits. They are mostly single-floor cages for single-action transport with a counterweight, purpose-built for the transport of machinery used on a given floor and its needs. Parametrically, they are operated with a lower load capacity (for two mine carts), lower speeds and with a sliding guide of the cage along wooden guides. The suspension is single-rope or four-rope. The construction is classic – supporting frame, rope suspension, cage guide, floor, roof, side covering and front door either fixed or louvered. The floor is equipped with rails for mine cars, the roof is supplemented with a supporting element of the suspension track, and its surface is covered with railings and a canopy.
Emergency cages
They can be stable and mobile. The smallest non-guided mobile cage of circular cross-section is transported as part of a mobile emergency transport device. Stable cages are either permanently suspended, or are suspended in operational condition before their use. They are then guided in the profile of the pit by guides, or by a guide and the rope of the mining equipment. These cages then have their own stable mining machine or are mounted on a mobile machine. Unguided cages have a cylindrical shape with conical tapers. Guided cages are mostly rectangular in cross-section. Structurally, they include a supporting frame fitted with a floor, roof, rope suspension, cage guide, side covering and entrance door. They are dimensionally adapted to the profile of the operated pit.
