Traveling
Blocks
LeTourneau Technologies™ Drilling Systems traveling
blocks are available in 500, 650, 750, and 1,000
ton models. Precise weighting ensures fast free-fall,
while their streamlined, compact design eliminates
interference with mast or derrick components.
Long service life is enhanced through quality
fabrication and advanced metallurgy of sheaves,
hooks, and other components. Direct coupling to
top drives and for motion compensating drawworks
further optimize high performance.
