In view of poor technological adaptability, low drilling efficiency and high energy consumption of engineering drill in construction process, a new full hydraulic engineering drill with load feedback system is introduced in this paper, which has the advantages of strong adaptability, energy saving, long drilling footage, large pulling force and automatically screwing. The field geological exploration results show that CTG-200 type full hydraulic can solve the difficulties in the construction with its characteristics of smooth crawler travel, stable performance, simple operation, short auxiliary feeding time, fast drilling tools lifting, convenient drilling tools removing and convenient construction for different hole positions in multi angles. The full hydraulic engineering drill is a new development direction to satisfy the demand of high efficiency and energy saving in today’s drilling market.
