1. Brief introductions of YQZ-50A hydraulic portable core drilling
rig
YQZ-50A hydraulic portable drilling rig is a small sampling
drilling equipment suitable for plains, mountainous areas and areas
with inconvenient traffic and energy. It is now widely used in
railway, water conservancy and other construction projects and
geological core drilling and small grouting holes in wild mountain
areas.
2. Features of YQZ-50A hydraulic portable core drilling rig
• Equipped with dual-cylinder hydraulic feed system, the drilling
speed is fast and the working efficiency is high.
• The drilling rig is equipped with a fixed clamping mechanism and
an integrated main rod, which does not require a drilling tower,
and the work is convenient.
• Equipped with a 4-speed transmission system. The operator can
freely adjust the forward rotation speed through three gears, and
is also equipped with a slow reverse gear, which is convenient for
the operator to disassemble the drill pipe and drilling tool.
• The handle is centralized, convenient to operate, safe and
feasible.
• Equipped with a pressure gauge at the bottom of the hole to
indicate the pressure, which is convenient for grasping the
situation in the hole.
• Compact structure and small floor space.
• Strong decomposition ability, easy to relocate, suitable for
hilly, mountainous and other complex terrain work.

- YQZ-50B Hydraulic Portable Core Drilling Rig
1. Brief introductions of YQZ-50B hydraulic portable core drilling
rig
YQZ-50B hydraulic portable drilling rig is a small sampling
drilling equipment suitable for plains, mountainous areas and areas
with inconvenient traffic and energy. It is now widely used in
railway, water conservancy and other construction projects and
geological core drilling and small grouting holes in wild mountain
areas.
2. Features of YQZ-50B hydraulic portable core drilling rig
• With oil pressure automatic feeding mechanism and high drilling
efficiency.
• The ball card clamping mechanism is used with a hexagonal active
drill rod, and the rod can be reversed without stopping the
machine.
• The drilling rig is equipped with hydraulic hoist, which is
convenient and efficient when used in conjunction with the drill
tower.
• Equipped with 4-speed shifting system. It is convenient for the
operator to freely adjust the forward rotation speed according to
the geological conditions, and is also equipped with a slow reverse
gear, which is convenient for the operator to disassemble the drill
rod and drilling tool.
• The handle is centralized, convenient to operate, safe and
feasible.
• Equipped with a pressure gauge at the bottom of the hole to
indicate the pressure, which is convenient for grasping the
situation in the hole.
• The drilling rig is equipped with a shift slide, which can
quickly replace the drilling tool, saving time and effort.
• Compact structure, small size, light weight, small floor space.
• Strong decomposition ability, easy to relocate, suitable for
hilly, mountainous and other complex terrain work.
