Explosion-proof air winches deployed for offshore drilling rigs & marine terminal logistics
Navigating the highly demanding marine environments of the Gulf of Guinea
Equatorial Guinea's industrial and economic framework relies deeply on offshore oil and gas extraction across major regions like the Bioko Basin and Rio Muni. Offshore fields such as Zafiro, Alba, Ceiba, and the Okume complex operate under extreme climatic stresses. These projects experience constant relative humidity exceeding 90%, high salt spray, and extreme heat. Under these harsh conditions, standard lifting systems fail rapidly due to galvanic corrosion and mechanical strain.
Furthermore, because operations handle volatile hydrocarbons, spark safety is a critical priority. This makes electric hoists and winches a liability without expensive explosion-proofing. Heavy-duty air winches (pneumatic winches) operate without electricity, generating zero sparks. They represent the primary reliable solution for offshore lifting, pipeline positioning, marine towing, and heavy rigging in oilfields and offshore logistics hubs such as Malabo Port and Luba Free Port.
As a leading exporter, Chongqing Glinder Lift Co., Ltd. provides customized pneumatic pulling and hoisting equipment engineered specifically for the Gulf of Guinea. Our air winches are designed to resist salt spray corrosion and deliver high load capacities. They also feature fail-safe braking mechanisms to meet international safety criteria, including ATEX Zone 1 / Zone 2 certification and ABS marine classifications.
Pneumatic motors do not generate electrical sparks, making them ideal for Zone 1 and Zone 2 hazardous gas environments.
Our offshore air winches undergo strict testing to receive ABS and DNV marine certifications.
Finished with heavy epoxy marine coatings and stainless steel hardware to resist salt-water environment degradation.
Equipped with radial piston motors that provide high starting torque and stepless speed adjustment.
Next-generation lifting solutions built to survive the world's most demanding environments
The global lifting industry is shifting toward smart, energy-efficient, and highly reliable technologies. At Chongqing Glinder Lift Co., Ltd., our engineering roadmap focuses on integrating structural durability with digital control systems. Our goals include:
Traditional carbon steel winches require constant maintenance to avoid corrosion damage from salt spray. Our engineering team uses high-strength structural steels combined with fluorocarbon and thermal-sprayed aluminum coatings. This prolongs equipment life on offshore platforms in West Africa. We also incorporate internal components made of high-tin bronze and marine-grade stainless steel to prevent mechanical seizure and reduce structural degradation.
Offshore lifting operations require redundant braking mechanisms. Our heavy-duty pneumatic winches feature automatic multi-disc wet brakes along with manual band brakes. The automatic disc brake activates instantly if control pressure is lost, ensuring loads are held securely. This capability is vital during emergency shutdowns on FPSOs and deepwater drilling vessels.
Industrial compressed air requires significant energy. Our next-generation air winches use optimized piston configurations and variable displacement motors. This design reduces air consumption by up to 18% during partial-load operations, lowering energy costs for operators in remote locations like the Zafiro and Alba oilfields.
High-capacity marine, mining, and industrial air winches for diverse pulling applications
High precision, automated production processes delivering globally compliant lifting equipment
Chongqing Glinder Lift Co., Ltd. is a specialized manufacturer and global supplier of heavy lifting equipment, material handling systems, and rigging hardware. Operating with over 15 years of industrial experience, we manage a manufacturing network designed to deliver reliable products at competitive prices.
Our manufacturing facilities are ISO-certified. We combine advanced machinery with a strict quality management system to ensure that our equipment meets safety standards, including CE and GS certifications. Our facilities feature heavy-duty presses, welding setups ranging from 50 to 2000 tons capacity, laser cutting systems, and high-precision CNC machining centers. This production network allows us to scale manufacturing while maintaining quality control for our clients worldwide.
Our engineering team applies safety design principles from German and Japanese lifting systems. Every air winch, manual hoist, and rigging component undergoes comprehensive testing—including non-destructive testing (NDT), load testing, and material analysis—prior to dispatch. This approach minimizes downtime and helps maintain operational safety in demanding industrial environments.

Our production facilities utilize automated machinery and testing benches to ensure consistent output quality. Below are the key stages of our manufacturing process, showing the steps from raw material verification to final product testing.
Ensuring reliable delivery and compliance for complex maritime supply lines
Procurement departments operating in Equatorial Guinea face distinct logistical and regulatory conditions. Delivering capital equipment to destinations like Malabo, Bata, or the Luba Free Port zone requires careful coordination. Delays in shipping can lead to downtime for offshore operations, making reliable transit schedules a priority.
Chongqing Glinder Lift Co., Ltd. manages shipping logistics through relationships with global ocean carriers, enabling reliable transport to West African ports. We coordinate all export documentation, including Certificate of Conformity requirements, bill of lading procedures, and customs clearance protocols. This setup helps reduce customs delays upon arrival.
We provide comprehensive packaging for international transit. All air winches and lifting systems are shipped in reinforced, moisture-barrier wooden crates. Sensitive valves, piston air motors, and automatic control systems are vacuum-sealed with desiccant protection. This process ensures the equipment remains protected against salt-air exposure and humidity during sea transport.
Additionally, we maintain an inventory of key replacement parts at our central warehouse. This allows us to supply replacement parts—such as vane motors, control valves, brake discs, and high-tensile link chains—rapidly when required. This support system helps operations in the Gulf of Guinea minimize downtime and maintain productivity.
Our engineering services also include remote technical support. We assist local technical teams with step-by-step guidance for installation, pressure testing, and periodic maintenance, helping ensure the equipment operates safely and according to specification.
