In recent years, new technologies related to battery drive have begun to reach transport with suspended tractors. Battery railways are intended for operation in underground mines in non-methane and methane fields as well as in excavations classified to all class of coal dust and methane explosion hazards. They can move on tracks with a longitudinal inclination of up to ±30° and work with or without operator's cabins, as shunting tractors using control from the desktop (with an electric cable or radio). Batteries can be charged in any excavation through the transformer unit - charger. The development in battery technology allows the use of cells without the „cell memory effect". This allows the tractor to be recharged without losing battery capacity. These tractors can be equipped with an innovative technology of mobile lighting of passenger and material stations as well as wireless radio control. They can cooperate with a transport set equipped with winches, and additionally installed 3 x 230 V sockets allow for cooperation with electric winches. The manufactured tractors have undergone appropriate certifications, tests and obtained decisions of the President of the State Mining Authority, allowing them to be used in underground mines. The operation of bat¬tery tractors in underground excavations, based on the experience gained, has shown a number of their advantages contributing to the improvement of work safety and efficiency. However, it must be remembered that the operation of battery tractors is limited due to the battery charging time, and the weight of the batteries limits their range.

W artykule scharakteryzowano dołowe ciągniki podwieszone z napędem akumulatorowym typu CA-190 i VOLTER, które coraz częściej stosowane są w transporcie kopalnianym. Opisano proces ich certyfikacji i dopuszczania do stosowania oraz - w oparciu o doświadczenia uzyskane podczas eksploatacji - przedstawiono zalety ciągników akumulatorowych, które przyczyniają się do poprawy bezpieczeństwa i efektywności pracy.
