瑞士LUMESA公司從1985年即開始生產模塊化鉆機，所謂模塊化是指：單部件重量40-50kg （最大1400Nm)，或80-120kg（最大5000Nm）的鉆機，鉆機的鉆架、動力頭、液壓動力組、控制器均可分拆并方便的組裝，特別適合如山地、大壩、隧道等各種特殊地形，還可以根據要求定做，應用在如TBM、工程車等平臺。該鉆機還可安裝在腳手架平臺，可方便地在任何工況下工作；工作能力媲美大型履帶式鉆機。
During the execution of avalanche protection works in 1985 in the Swiss
mountains, a problem arose.There they had to carry out jobs, which were usually done with heavy crawler mounted drill rigs.
The problem was solved. Today we have a great variety of components that
allows us to build 4 different sizes of machines in a modular system.
We have components weighting 40 – 50 kg for the lightest machine (Max.
torque 1400 Nm) as well as components weighting 80 – 120 kg for the more
powerful machine (max. torque 5000 Nm).
