TracMec’s extendable undercarriage enables operators to use a reduced width for transportation and increased width for greater stability.

This is the most common type of extendable undercarriage and is used mainly for drilling rigs and cranes application.

Extendable undercarriages are available as telescopic, parallel and opposite extensions.

The telescopic undercarriage is one of the most common used for drilling rigs. The parallel undercarriage is one of the most stable models and features the option to hydraulically clamp at any width status of the undercarriage, by providing a continuous multiple-stage width enlargement.
