Limited Access Rig

The Limited Access Rig (LAR) is a cost-effective solution for limited-access drilling, In easy to moderately hard drilling. We need just 42 in. of clearance for width and 9 ft. overhead for mobilization. This rig can be partially dismantled to access low ceilings and doors. The LAR is ideal for drilling holes from 12 to 36 in. diameter and depths of up to 85ft. with out stemming. The rig is capable of sampling and down-hole logging. Steel tracks and a rear backhoe make the LAR a versatile rig for limited access areas and hillsides. For areas with no access to track the rig in, a crane can be used to place the LAR in the desired location. Plywood sheets are used to protect landscaping, designer driveways and masonry.
