Telescopic Gearboxes

EBI designs and manufactures the (TGB), a telescopic gearbox, for use on their telescopic boom marine cranes to extend and retract the inner boom externally. The gearboxes outside of the boom make it easier to service and maintain. They also utilize EBI’s 12-tooth pinion legendary design for better contact ratios, more secure handling, and more speed diversity.

All EBI Gear Reductions are designed and manufactured to meet all requirements set forth by API Spec 2C, ABS, USCG and OSHA.
