Traveling Blocks
National Oilwell traveling equipment is available in a broad range of
models and sizes, to meet any rating or specific application. New
designs for direct couple to top drives and for motion compensating
drawworks have been developed to enhanced performance and
operability.
• They are rated in accordance with the API yield strength method.
• Proper, precise weighting ensures fast free-fall.
• Streamlined, compact design means there is no interference
with mast or derrick components.
• Metallurgy of sheaves, hooks, and other components are care-
fully matched to provide long, trouble-free service.
• Certification from most third party available upon request.
• API-8C versions are available upon request.
