Product Introduction
PRODUCT FEATURES:
Power system, drawworks, mast, travelling system and transmission system of the workover rig are mounted on
the self-propelled chassis, and the rig has features of easy transportation, low moveable cost, reliable performance,
high operating load, high cross-country power and others;
Basis parameters and the overall design of the workover rig conform to GB/T 23505-2009 and SY/T 6724-2008; Mast,
substructure, travelling block, hook, crown block, swivel, rotary table, mud pump and other main equipment conform to
API specification and HSE requirements and are marked with API monogram;
Utilize mature, reliable and practical advanced technology and use imported parts for diesel engine, transmission case,
control valve and other critical components.
