Drawworks

Solid Machines

LeTourneau offers three models; the LDW3000 (3000 input hp), the LDW3000 Heavy-Duty (3000 input hp), and the LDW4500 (4500 input hp). Hoisting power is provided by a two or three motor drive system, which can either be variable frequency AC or SCR controlled DC. Plus, chain-driven drawworks are equipped with a powerful disc braking system featuring hydraulically applied service brake calipers as well as spring-actuated emergency / parking brake calipers for operational safety. All chain-driven drawworks come mounted on oilfield-type skids with provisions for crane lifting and easy tailboard loading onto transport trucks or rig structures.

Operational Efficiency

LEWCO AC Gear-Driven Drawworks offer technically advanced features to increase drilling performance, safety and reliability. The combination of both cost and operational efficiency with a smaller footprint, less weight, reduced noise, and smoother operation further adds to the advantages provided by these solid machines.

Offered in a choice of 550K, 750K, 1000K, 1500K, and 2000K hook load models, these advanced systems feature a triple braking system for increased safety, including an emergency brake and regenerative system. Higher operational speeds are achieved in all models through the exclusive use of Variable Frequency Drive (VFD) AC motors.

With fewer utilities required for installation and fewer spare parts, the LeTourneau AC Gear-Driven Drawworks is a solid choice for enhanced performance, safety, and unmatched reliability.
