RMT 73, equivalent to LaCruz M37B, is a lightweight pneumatic hammer (martillo neumatico), but, even being lightweight, it is a powerful pneumatic chipping hammer, especially made for mining and related field operations. The RMT 73 is 100% equivalent to the LaCruz M37B, making it a useful option for users who need direct OEM-style replacement performance.
This model is preferred in coal mines, soft ore zones, and general underground maintenance where controlled impact and operator handling matter. It works well on soft rock, mineral seams, and surface cleaning tasks in mining operations.
The RMT 73 (LaCruz M37B) weighs 8.5 kg. If you need lighter version than this, then you can also select LaCruz ML 33 Marillo (RMT 66); it weights 5.5 kgs and similarly also used in the same applications as the M37B.
