Real Torque

For Tight Access

BUILT TO GO WHERE BIGGER RIGS CANNOT

LAD stands for Limited Access Drilling, and that’s exactly what these rigs were built for—getting into places where overhead, access, and working room rule out a conventional drill. Compact carriers, low attachment heights, and unobtrusive frames make them a good fit inside buildings, around residential foundations, beneath power lines, and anywhere space is limited.

The LAD series will bring drilling capacity to your toughest jobsites, giving crews depth, torque, and control in the places traditional equipment can’t fit.

When Space Is Limited

Every Inch Matters

When access is limited, every part of the rig has to work within the space available. Each LAD is configured around the job’s overhead clearance, access points, carrier requirements, drilling depth and ground conditions. From attachment height and mast configuration to the rotary, winch and kelly bars, we work with you to build a rig that fits the site and still delivers the drilling performance the work demands.

The goal is not simply to mount a drill on an excavator. It is to turn the excavator into the drilling machine the work demands.

rotary

Bay Shore designs and builds its rotary gearboxes in-house, with torque capacities from 14,200 to 40,000 ft-lb. Match the rotary to the size of the work instead of carrying more machine than the job calls for.

Winch

Match the Kelly winch to the rig and drilling depth, with single-layer line pull up to 18,000 lbs across the LAD lineup. The right winch gives the operator the pull needed to bring the Kelly and tooling back out of the hole without oversizing the machine.

Kelly Bars

Choose round-locking or square friction Kelly bars based on drilling depth and ground conditions. Round-locking bars give the operator positive locking points when crowd needs to be transferred through the Kelly; square friction bars provide another way to match the rig to the depth and work.

Attachment

Configure the rig around the space above the hole and the depth below it. Taller attachment configurations support deeper drilling, while shorter setups put the rotary to work where power lines, bridges, and other overhead restrictions limit working height.

Carrier

Configure the LAD around a compact carrier that can reach the work. Bay Shore Systems can build on nearly any major manufacturer’s platform, whether it comes new from the dealer or from your existing fleet.

MORE WAYS

TO BUILD YOUR LAD

From downhole visibility and powerline detection to adjustable crowd force and faster leveling. LAD series’ add-ons let you equip the rig around your applications, crews and jobsites.

Downhole Camera

Real-time visibility into downhole conditions, casing advancement, and hole stability.

People Detection System

AI-assisted in-cab displays alert the operator if people are present in the configurable safe zones.

Overhead Powerline Detection

Safety system used to detect proximity to energized high-voltage power lines.

Return To Level

Leveling to within 0.5 degrees for faster and more precise rig setup.

Variable Crowd

Allows operators to dial in and maintain the optimal downforce in hard rock, ensuring a steady penetration rate while preventing tool stalling or glazing.

Smart Controls.

Real-Time Results.

Integrated control systems give operators clear feedback and responsive control to maintain consistent drilling performance. Designed for real jobsite conditions, these controls help reduce operator fatigue while improving accuracy and efficiency throughout the drilling cycle.

Seamless Operation

The EOH system unifies excavator and drill head functions so operators stay focused on drilling.

Touchscreen Adjustments

Tune torque, crowd force, and rotary speed on the fly to match changing ground conditions instantly.

Faster Fixes

Built-in diagnostics cut troubleshooting time from days to hours.

Operator Insight

Track run hours from the cab to support better maintenance planning and operator accountability.

Carrier Ready

Fully compatible with the latest EOH excavators—so you get the rig you want, on the machine you choose.
