STS Spare Parts By Features
Our extensive drawings covers critical components to keep your STS cranes operating at peak efficiency.Each component is manufactured to exact OEM specifications, ensuring effortless installation and flawless operation.
A high-friction material designed for reliable stopping power, excellent heat resistance, and extended service life under heavy loads.
A critical safety system providing precise control, reliable stopping, and holding power to ensure safe container handling operations.
An energy-absorption device that protects the crane’s structure by absorbing and dampening impact forces at the end of the runway.
A precision-grooved wheel that guides and routes cables efficiently, reducing wear and friction for smooth power transmission.
A connecting device that joins two shafts, efficiently transmitting torque while compensating for minor misalignments and reducing vibration.
The robust sealed drum bearing unit could supports the hoist drum shaft, ensuring smooth rotation, high load capacity, and minimal maintenance.
A heavy-duty connection that directly links the gearbox output to the hoist drum, ensuring positive torque transmission for lifting operations.
A large, cylindrical spool that winds the wire rope in an organized manner, providing the core mechanism for hoisting and lowering loads.
A high-torque reduction unit that converts the motor’s high speed into powerful, controlled low-speed motion for lifting and trolley travel.
The main lifting frame that connects to the spreader, equipped with sheaves and guides for wire ropes to distribute load weight evenly.
A small hoisting system providing a critical utility for safely lifting tools and parts during maintenance and repairs on the crane.
A securing system that firmly holds the rail in place while damping noise and vibration, ensuring stable and smooth crane travel.
A set of guided or support rollers that ensure smooth, low-friction movement of the trolley or gantry along its designated path.
Grooved wheel can changes direction of the wire rope, increasing mechanical advantage with minimal loss of efficiency.
A safety device designed to catch and support the spreader in the event of a hoist system failure, preventing it from falling.
A rotating locking mechanism that securely fastens the container to the spreader or containers to each other for safe lifting and transport.
A flexible, high-strength cable made of steel wires wound into strands, designed for hoisting heavy loads with durability and reliability.
Complete bogie unit that includes the wheel, axle, bearings, and housing, providing foundation for crane’s movement along the rails.

Application Scenarios of STS Spare Parts
Hoisting System: Components like the Wire Rope, Sheave, Drum, Drum Bearing Housing, Gearbox, Brake, and Brake Lining work in unison to vertically lift and lower heavy containers from the vessel to the transport vehicle below.
Spreader System: The Twistlock is the crucial device that physically locks onto the container’s corner castings. The Headblock serves as the interface between the hoist ropes and the spreader.
Trolley Traverse System: This system moves the container horizontally between the ship and the apron. The Cable Pulley guides the power and control cables, while the Roller Assy ensures the smooth movement of the trolley along its beam.
Gantry Travel System: The Wheel Assembly supports the entire weight of the massive crane and enables its travel. Rail Clips and Rail Pads secure the rail to the foundation and dampen noise and vibration, protecting the infrastructure.
Safety & Impact Protection: Buffers are installed at the ends of the rail to absorb the kinetic energy in case of an over-travel event, preventing structural damage. Slap Blocks act as a mechanical safety device to catch falling components.
Maintenance Handling: The Maintenance Crane (a smaller onboard hoist) is a critical utility tool used to lift and transport heavy components (like motors, gearboxes, or new wire ropes) during maintenance and repair work on the quay crane.
Power Transmission & Drivetrain: Couplings and Drum Couplings connect drive shafts, transmitting torque from motors to driven equipment. Their precise alignment is vital for longevity and is a key focus during maintenance.
Absolutely. Our critical components (like wire ropes, brake linings, and sheaves) are produced in strict compliance with relevant ISO, DIN, and ASTM standards. Our operations are certified under ISO 9001 Quality Management Systems. We implement rigorous quality control from raw material sourcing to final inspection, ensuring every part meets or exceeds OEM specifications for performance and safety.
Our brake linings are made from high-performance, non-asbestos composite materials. They offer excellent and stable friction coefficients, superior heat dissipation, and reduced noise. Testing shows a service life equivalent to, and often longer than, OEM parts, especially in high-cycle applications, reducing your total cost of ownership.
Our wire ropes are engineered specifically for heavy-duty port cranes. They provide a very high guaranteed breaking strength and exceptional resistance to bending fatigue. We use tough core materials and specialized spinning techniques to ensure greater durability and resistance to broken wires under high loads and frequent drum winding.
Yes. We supply compatible parts for all major crane brands (ZPMC, KONE, Noell, Paceco, etc.). Please provide the crane’s manufacturer, model, and the OEM part number. We maintain an extensive database of technical drawings and dimensions and can also cross-reference based on a sample or drawing you provide to guarantee a perfect fit.
We maintain safety stock for fast-moving wear parts like wire ropes, brake linings, twistlocks, and buffers. These can typically be shipped within 3-7 business days. For larger, custom-made items like gearboxes, drums, or wheel assemblies, the standard production lead time is 4-8 weeks. We will always provide a precise delivery schedule based on your order.
We use export-grade, robust wooden/steel crates for all shipments. Precision-machined surfaces (e.g., bearing seats, gear teeth) are coated with anti-rust oil and protected with covers or vacuum film. Internal cushioning with foam and custom brackets is standard to ensure products arrive at your terminal safely and without damage.
Most components (like rail pads, twistlocks, buffer) can be installed by your maintenance team using standard procedures. For precision assemblies like gearboxes, drum bearing housings, or wheel assemblies, we highly recommend professional installation. We can provide detailed installation manuals, videos, and can dispatch our engineers for on-site technical support (subject to separate arrangement).
