Product Introduction
PQZ-350L mechanical top drive driling rig is a driling equipment independently developed by the company thatcan drill 90" and integrates the functions of water drill and air drill(National Invention Patent: 2L201510479602.4). it adopts5-speed manual car transmission. wide speed range, sensitive and convenient forward and reverse switching, hightransmission efficiency, greatly reduced power energy consumption, more efficient and energy-saving. lt solves the dificulty ofdriling with air down-the-hole hammers in soil lavers and the low construction efficiency of rotary driling rigs in hard rocklayers, gravel, and pebble layers.
