The Full Hydraulic Drilling Rig GXY 44 (Crawler Core) is a heavy duty full hydraulic crawler core drilling rig developed for medium deep geological exploration projects, complying with international geological survey and mechanical safety standards. Designed for 1000 meter medium deep core sampling tasks, the GXY 44 adopts full hydraulic stepless transmission system together with reinforced crawler travelling undercarriage. It supports diamond coring, wire line coring and carbide bit drilling processes, delivering stable performance for hard rock, fractured rock and complex composite stratums. Integrated crawler chassis enables autonomous transfer on mountainous, hilly and muddy sites without auxiliary transportation equipment. Equipped with high rigidity hydraulic mast, multi group leveling outriggers and centralized hydraulic control console, the rig ensures high core recovery rate and reliable long duration field operation. It is widely adopted in mineral resource exploration, highway railway engineering geological survey, hydrological geology investigation and geotechnical engineering projects worldwide, acting as a cost effective medium deep coring solution for geological institutes and drilling contractors.
Industrial full hydraulic drive realizes stepless adjustment of rotary speed, feeding pressure and pull back force. Constant torque output adapts dynamically to variable rock hardness, effectively reducing drill jamming risks in hard and fractured formations. Smooth hydraulic power transmission lowers impact vibration during deep hole coring and protects rock core from fragmentation.
Reinforced engineering crawler undercarriage features low ground pressure, anti slip and anti sink performance. It can travel freely over mountain slopes, gravel ground and muddy wild construction sites. Independent hydraulic travelling motors support in situ steering and precise on site repositioning, solving relocation difficulties of conventional skid mounted exploration rigs.
Optimized spindle assembly and long stroke hydraulic feeding mechanism perfectly match wire line coring technology. It avoids repeated tripping of drill rods, greatly improving field coring efficiency and core integrity. Reliable hydraulic chuck provides stable clamping force for drill string during continuous medium deep drilling.
Highly modular layout for power pack, hydraulic station and drilling working unit. Hydraulic automatic mast erecting and multi point synchronous leveling outriggers allow fast setup upon site arrival. Complicated foundation treatment and piece by piece assembly are eliminated, shortening rig up cycle for batch exploration missions.
Integrated control console with intuitive operating logic lowers operator learning threshold. Major hydraulic and wearing components adopt globally available standard specifications. Modular assembled structure simplifies inspection and part replacement, decreasing long term field maintenance cost.
Key load bearing steel components receive multi layer wear resistant, anti rust and anti corrosion treatment. Hydraulic and electric assemblies are fitted with dust proof, splash proof and wide temperature protection modules. Stable continuous operation is available under high temperature arid, low temperature alpine, windy dusty and rainy humid outdoor field conditions.

The GXY 44 full hydraulic crawler core drilling rig is a different species from the deep oil and gas platforms above: it drills to 1000 m for core samples, not wells. Rated coring diameters of 75, 91 and 110 mm, a spindle that spins to 1050 r/min through hydraulic stepless regulation, and a 4200 N·m output torque define what it can cut — diamond coring, wireline coring and carbide drilling in hard rock, fractured rock and mixed overburden. On its crawler undercarriage it walks itself across mountains, hills and muddy sites at up to 2.8 km/h, which removes the truck-access problem entirely for geological survey work.
Before you request a GXY 44 core drilling rig quotation, send us the rock types and core diameter your survey specifies, plus the terrain between survey points: the 72 kN feed / 78 kN pull-back force and 22 MPa hydraulic system are standard, but the power choice — 92 kW diesel engine or optional electric motor — depends on whether your sites have grid access. For highway, tunnel, bridge and foundation investigation projects, tell us the borehole count and spacing so we can confirm the machine's daily coring throughput against your schedule.
GXY 44 pricing is quoted per power configuration and tooling package; a benchmark figure is returned within 48 hours of your survey parameters.
Customize hydraulic torque and feeding thrust parameters for hard rock or heavily fractured stratums; match dedicated wire line coring tool set to raise core complete rate and drilling efficiency.
Optional widened anti sink crawler tracks and reinforced chassis suspension for swampy, soft ground and steep slope wild exploration environments.
Optional ultra low temperature cold start package for alpine regions; enhanced full system dust proof and sand sealing configuration for arid desert field operations.
Optional real time drilling parameter monitoring, automatic depth counting and operation data recording modules for digital exploration site management.
Provide personalized painting, exclusive brand logo marking, complete coring tool package, on site commissioning training and 24 hour full process after sales technical support.
