Electric winches

OverviewThe auxiliary electric winch for oil drilling rigs is driven by a variable frequency (or line frequency) electric control system powering an explosion-proof AC variable frequency (or line frequency) brake motor, which drives the drum through a reducer to spool or pay out wire rope for hoisting/lowering loads.

Product Introduction


The auxiliary electric winch for oil drilling rigs is driven by a variable frequency (or line frequency) electric control system powering an explosion-proof AC variable frequency (or line frequency) brake motor, which drives the drum through a reducer to spool or pay out wire rope for hoisting/lowering loads. It features low energy consumption, high efficiency, safety and reliability, high automation, simple structure, smooth transmission, and is capable of meeting operational requirements in desert, rainforest, polar and offshore environments.

Our core R&D team has over a decade of experience in electric winch design and engineering. Key members previously served as principal technical leads for auxiliary electric winches used on Chinese petroleum drilling rigs and workover rigs, took the lead in drafting relevant industry technical standards, and are recognized as driving forces in the technological advancement of this sector. Leveraging solid technical expertise and extensive field experience, we provide customers with mature, reliable electric winch products and technical support.

The Starting Point of Electric Auxiliary Winches for Chinese Drilling Rigs — 2019, Lenghu Area, Huatugou, Qinghai



This photo captures the on-site installation and commissioning of the first electric auxiliary winch for petroleum drilling rigs in China. From this moment on, the auxiliary winch industry began its technological revolution — transitioning from pneumatic and hydraulic to electric drive. Core members of our team led and participated in the entire journey: design, testing, field commissioning, upgrades, and the evolution from line-frequency to variable-frequency drives, from personnel-only to personnel-and-load dual-purpose winches, and ultimately to a full series of automated winch products. We also took the lead in drafting the industry standard. Ten years of sharpening a sword — and we are still on the road.



Technical Features

● Energy-saving & high efficiency: Significantly reduced energy consumption and improved efficiency compared to traditional pneumatic/hydraulic hoisting equipment;

● Excellent speed control: Variable frequency drive enables smooth stepless speed regulation with stable operation and precise control; line frequency drive offers economical and reliable performance for conventional operations;

● Multiple braking protection: Equipped with motor dynamic braking + motor disc brake + drum band brake, ensuring safety and reliability;

● High automation: Automatic braking and wire rope spooling control; optional PLC for intelligent operation;

● Generally featuring wide regional adaptability, simple structure, and easy maintena
