Machinery is often too large to send to our workshop.

Active's lineboring division brings our quality workshop service out to the customer's site. 

Fully-mobile lineboring:

On-site lineboring saves our customers the cost and downtime involved in disassembling and shipping equipment. It also allows the repair process to be carried out under the customer's oversight. Active's equipment has all been sourced, designed or custom-built so that even in the field we can work to strict tolerances and meet the highest factory standards.

An experienced team and our fleet of mobile vans means we can provide a rapid response for on-site emergency repairs, modifications or planned maintenance. Our vans are well-stocked so we rarely need to interrupt our work to leave site. For larger projects we have specialised equipment in transportable units that can be quickly shipped to site.

Active's lineboring staff are master craftsmen, skilled in fitting and turning, welding, tool making and mechanical problem-solving. Our work includes hole building and boring (up to 16 per day), fabrication, crack repairs, rebuilds, joint and pivot repairs and maintenance. We always carry stock of high quality Acti-Bush hardened pins and bushes to get equipment running again in the shortest possible time.
