The container spreader is the core operating component used by port, terminal, railway yard, and shipboard cranes for lifting containers. It connects to the container corner castings via twist-lock mechanisms, enabling rapid loading and unloading. We provide professional transport services from manufacturing plants, repair workshops to ports, container yards, shipyards, or operational sites. Spreaders can be shipped as a whole or in dismantled parts.

Common Types

• Fixed Spreader (dedicated to 20ft or 40ft containers)

• Telescopic Spreader (adjustable between 20ft and 40ft)

• Twin-lift Spreader (capable of lifting two 20ft containers simultaneously)

• Shipboard Container Spreader (for ship-mounted cranes)

• Spreader Headblock (connecting crane wire ropes to the spreader)

• Twist-locks and hydraulic accessories (shipped independently)

Key Transport Challenges

• Elongated and Irregular Shape: Spreaders are typically long rectangular frames, 6 to 12 meters in length, about 2.5 meters wide. Twist-lock mechanisms, hydraulic cylinders, cable ducts, and control boxes protrude around the perimeter.

• Heavy Single-Unit Weight: Standard spreaders weigh 3 to 8 tons; twin-lift or heavy-duty spreaders can reach 10 to 15 tons.

• Precision Components Prone to Damage: Twist-lock pins, proximity switches, hydraulic hoses and fittings, sensors, and other precision parts protrude beyond the spreader frame, making them vulnerable to bending, breakage, or leakage during transport impact.

• Uneven Weight Distribution: Hydraulic power units and cable reels are often located on one side, requiring careful balance point identification during lifting and loading to prevent tilting.

• High Surface and Mounting Surface Requirements: The bottom face of the spreader (the contact surface with the container) must remain flat and free of dents; otherwise, twist-lock alignment may be affected. Paint damage may result in port rejection.

• Oversized Dimensions Common: 12-meter spreaders exceed the length of standard flatbeds, requiring oversize transport permits.

Our Transport Solutions

1. Packaging & Protection

• Whole spreaders are transported bare on low-bed flatbeds. Place wooden sleepers or rubber pads under the spreader, avoiding twist-locks and sensor locations.

• Protect protruding components such as twist-lock mechanisms, hydraulic valve blocks, and proximity switches with bubble wrap or rubber protective sleeves, covered with plastic caps.

• Fit dust caps or seal tape on hydraulic hose fittings, cover with plastic bags and tie securely to prevent oil leakage and foreign matter ingress.

• Coil control cables and plugs separately, label them, place in waterproof bags, and secure in the spreader's internal empty space.

• For dismantled components such as headblocks and twist-lock assemblies, use wooden crates or steel-frame boxes with internal cushioning material.

2. Lifting & Securing

• Lift using the spreader's built-in lifting lugs. Confirm the rated load of the lugs before use.

• If lugs are unsuitable or inconveniently located, use nylon slings for basket lifting, passing through structural holes in the spreader main beam, avoiding hydraulic cylinders and hoses.

• Place wooden dunnage under the spreader on the flatbed so that twist-locks are suspended and not subjected to pressure. Secure using chains or straps from four directions: both ends and the center.

• For spreaders exceeding 12 meters in length, install warning lights and reflective markings on the vehicle tail.

3. Transport Modes

• Open-top container: suitable for small fixed spreaders of about 6 meters. Load the spreader and secure both sides with air bags or wooden dunnage.

• Flat rack container: suitable for 8- to 12-meter spreaders. Place the spreader directly on the flat rack floor and secure around the perimeter with chains.

• Breakbulk on deck: suitable for large quantities or over-length spreaders. Bare stowage with welded bases and lashing.

• Road Transport: Use low-bed flatbeds or extended flatbeds. For over-length spreaders, apply for oversize transport permits in advance and plan the route.

• Sea Freight:

• Multimodal Transport: Road + sea combined for door-to-door service from factory to destination port.

4. Value-added Services

• Pre-shipment photos of key parts such as twist-locks, hydraulic piping, and control boxes.

• Assistance with export customs declaration (HS code typically falls under crane accessories or container handling equipment).

• Coordination of crane offloading at destination port and placement at customer's designated location, such as terminal equipment warehouse or yard.

• Anti-rust treatment for flanges and exposed metal surfaces.

Our Advantages

• Long-term experience in container spreader transport; familiar with protection requirements for precision components such as twist-locks, proximity switches, and hose fittings. Lashing operations avoid stress concentration points.

• Inspect hydraulic hose fitting seals and apply leak prevention measures before shipment.

• Place soft wood or rubber under the spreader bottom face (container contact surface) to prevent paint scratches and local dents, ensuring arrival condition meets port acceptance standards.

• For spreaders of 12 meters or longer, apply for oversize transport permits in advance and declare the route to ensure legal and compliant passage.

• Spreader main body can be shipped together with twist-lock spare parts, cable reels, hydraulic power units, and other companion components in a single batch, reducing client coordination efforts.

• If the destination port lacks offloading equipment, arrange a mobile crane or truck crane in advance to assist unloading.
