CME-55LC

The CME-55LC has a unique feed and retract system and a quick disconnect mast that allows you to work under service station canopies, bridges or other overhead restrictions.

The CME-55LC gives you all the power and productivity of a full-sized CME-55. It is also available with many of the same options to help get the job done as efficiently as possible. The optional SPT hammer even has a separate valve for lifting the hammer when working in the low clearance mode that restricts the height that the hammer can be raised.
