LIebherr’s LB 35.1: Higher Performance, Deeper Depths

Why It Matters

The LB 35.1 gives contractors a high‑performance, deep‑drilling solution in a compact, mobile package, accelerating project timelines while lowering labor costs and site constraints.

Key Takeaways

• Lattice‑boom extension adds 6 m depth, now 37.5 m
• 603 hp engine boosts torque to 255,934 ft·lb
• Automated drilling assistant reduces manual concreting steps
• Modular leader and counterweights enhance flexibility and transport
• Ergonomic cab includes orthopedic seat and adjustable monitors

Pulse Analysis

The construction sector has increasingly demanded compact rigs that can reach the deep foundations traditionally reserved for larger equipment. Liebherr’s newest LB 35.1 answers that call with a lattice‑boom extension that pushes maximum drilling depth to 37.5 m, a full six meters beyond the previous model. Powered by a 603‑horsepower diesel engine delivering 255,934 ft·lb of torque and a 300 kN winch line pull, the rig combines raw power with a small footprint, making it suitable for urban sites and constrained job‑sites where mobility is critical.

Beyond raw capability, the LB 35.1 integrates a suite of automation tools that streamline the drilling workflow. The drilling assistant takes over concrete placement during continuous‑flight‑auger operations, while slack‑rope monitoring safeguards winch tension and automatic leader alignment ensures precise inclination without manual adjustments. An overload protection system for the Kelly winch and a real‑time Kelly visualization display further reduce operator error. These intelligent features cut cycle times, lower labor intensity, and align the rig with the industry’s shift toward digitally‑controlled, high‑productivity construction equipment.

Operator comfort is another focal point; the cab now offers an orthopedic seat, individually adjustable monitors and even a cool‑box for meals, reducing fatigue on long‑duration jobs. The modular leader and counterweight design allows the rig to be folded and transported in a single load, shortening set‑up time and enabling rapid relocation between sites. By marrying deep‑foundation capability with automation and ergonomics, Liebherr positions the LB 35.1 as a versatile solution that can accelerate project schedules while maintaining safety and efficiency standards.
