Mining equipments are expensive and dumping old equipments in a junkyard is very uneconomical. A lot of companies have come forward to mining equipment repair and remanufacture old mining equipments to give them back to you in ‘like new’ condition. Companies like Metalcraft offer only remanufacturing and they have a reputation of being reliable and offering good service. Swanson Industries offer mining equipment repair services on longwall roof supports and underground mining equipments.

These companies use devices like boring mills, burning tables and automatic bore welders to do the mining equipment repairs on the hydraulic supports and also give a six month warranty. Remanufacturing industries do a more complex job. They do a full check up on your equipment; decide what parts need to be replaced and what outdated parts need an upgrade. Once this is done they check up on the electrical system and finally do a paint job. All this will restore your old machinery to a ‘like new’ condition which will improve its performance and extend its life.
