Lifting large volumes of materials from the depths of underground mines is a struggle against gravity. It involves carrying dense rock in massive quantities, which equates to immense levels of strain on any equipment used. As such, mining skips must have extraordinarily rugged specifications to maintain efficiency and safety in the excavation process.

The skip must be able to carry large loads without being too heavy itself. Through the years, the mining industry has seen various developments in how skips are constructed, from the materials used to the design of the units. The use of aluminum alloys is pretty common because of the metal’s exceptional strength-to-weight ratio. The material’s downside is low-wear resistance, which is addressed by lining skips with abrasion-resistant steel, mild steel, or rubber.
