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.
