Product Advantages

High Cube Open Top Design

The 40'HC Soft Open Top Container combines a high cube container configuration with a removable soft roof, providing more vertical loading space than a standard-height open top container.

This configuration is suitable for cargo that requires additional height or cannot be conveniently loaded through conventional container doors.

The open roof allows suitable cargo to be lowered vertically into the container, while the PVC tarpaulin is used to cover the roof opening after loading.

Flexible Top Loading for Bulky Cargo

For machinery, industrial components and other bulky cargo, conventional horizontal loading through the end doors may be difficult due to cargo dimensions or handling limitations.

The soft open top configuration provides direct access from above and supports loading by suitable crane or lifting equipment where required.

This makes the container particularly useful for cargo with:

● Large overall dimensions

● Additional height requirements

● Irregular shapes

● Heavy or bulky structures

● Limited horizontal loading access

Actual loading arrangements should be determined according to cargo dimensions, weight and securing requirements.

Reinforced Steel Construction

The container is manufactured with a high-strength steel structure to maintain dimensional stability and structural performance during handling and transportation.

We use precision cutting and standardized welding processes during structural fabrication.

The container frame, side walls, end structures and other components are assembled according to the approved manufacturing design.

Anti-Corrosion Coating System

The steel surface undergoes Sa2.5 abrasive blasting before application of the specified coating system.

The standard coating configuration includes:

● Zinc-rich epoxy primer

● Epoxy intermediate coat

● Acrylic top coat

Paint thickness and coating adhesion are inspected during the coating process.

This surface treatment helps protect the steel structure against corrosion associated with outdoor storage, transportation and marine shipping conditions.

PVC Tarpaulin Roof Cover

The roof opening is covered with a removable PVC tarpaulin, allowing the container to be opened when vertical loading is required and covered after cargo loading is completed.

The flexible roof configuration provides a practical alternative to a fixed steel roof for cargo requiring top access.

Application

The 40'HC Soft Open Top Container is designed for international and multimodal cargo transportation where additional vertical space or top-loading access is required.

Over-Height Cargo

The high cube configuration provides additional vertical space compared with a standard-height container.

It is therefore suitable for taller cargo that requires more internal clearance or for cargo whose loading process makes a conventional closed-roof container impractical.

If cargo extends beyond the normal container profile, the shipment should be evaluated as an out-of-gauge transportation project according to carrier requirements.

Heavy Machinery

Industrial machinery and equipment that cannot be conveniently moved through conventional container doors can be loaded through the open roof using appropriate lifting equipment.

Typical projects may involve manufacturing equipment, mechanical units and other heavy industrial cargo.

Large Industrial Components

The container can be used for transporting bulky or irregularly shaped components where additional loading access is necessary.

Vertical loading can simplify cargo handling when the dimensions or shape of the component restrict conventional end-door loading.

Project Cargo Transportation

For project cargo requiring special loading arrangements, the open-top structure provides greater flexibility when preparing the cargo for containerized transportation.

Cargo weight, dimensions, center of gravity and securing arrangements should be evaluated before loading.

Multimodal Logistics

As an ISO shipping container product, the container is intended for multimodal transportation involving road, rail and sea logistics.

The final transportation arrangement remains subject to container certification, cargo specifications and individual carrier requirements.

FAQ

What is a 40'HC Soft Open Top Container?

It is a 40-foot high cube shipping container with an open roof configuration covered by a removable PVC tarpaulin.

The design combines the additional vertical space of a high cube container with convenient top-loading access.

What is the difference between the 40'HC and 40'GP Soft Open Top Container?

The main difference is container height.

The 40'HC High Cube configuration provides greater vertical space than the 40'GP General Purpose configuration.

This makes the HC version more suitable when cargo requires additional internal height or vertical clearance.

Exact internal dimensions are confirmed from the approved product drawing.

Why choose a soft open top container?

A soft open top container provides direct loading access from above.

It is useful for heavy, bulky, tall or irregularly shaped cargo that is difficult to load horizontally through conventional container doors.

What is the roof made of?

The roof opening is covered by a removable heavy-duty PVC tarpaulin supported by removable roof bows.

The tarpaulin can be removed when top-loading access is required and installed after loading according to the cargo arrangement.

Can cargo be loaded by crane?

Yes. Suitable cargo can be loaded vertically through the roof opening using a crane or other appropriate lifting equipment.

The lifting method must be selected according to cargo dimensions, weight, center of gravity and handling requirements.

What types of cargo can be transported?

Typical applications include:

● Heavy machinery

● Industrial equipment

● Large components

● Bulky cargo

● Tall cargo

● Irregularly shaped project cargo

Final suitability is assessed according to the specific cargo and transportation requirements.

Can this container transport over-height cargo?

An open top container can accommodate cargo that requires loading or clearance beyond what a fixed roof would allow.

However, cargo extending beyond the normal container profile may be treated as out-of-gauge (OOG) cargo.

Carrier approval, cargo securing, route restrictions and transportation arrangements should therefore be confirmed before shipment.

Does the PVC tarpaulin make the container completely waterproof?

The PVC tarpaulin provides a weather-tight removable covering over the roof opening to protect cargo from rain, wind, and marine spray during normal transit.

What anti-corrosion coating is used?

Our standard coating specification includes:

● Sa2.5 abrasive blasting

● Zinc-rich epoxy primer

● Epoxy intermediate coat

● Acrylic top coat

Paint thickness and adhesion are strictly inspected during production.

What standard does the container follow?

The container is designed and manufactured in full accordance with ISO 1496-1 requirements for Series 1 freight containers.

Can Boxwell provide a CSC Certificate?

Yes. A CSC Certificate is provided according to applicable order and transportation requirements.

Is this a DNV offshore container?

No. This product is categorized under ISO Shipping Containers for multimodal freight.

It is not an offshore container or CCU certified for offshore dynamic lifting under DNV-ST-E271 or EN 12079. For offshore lifting applications, our offshore CCU container line should be selected.

Are the dimensions and payload the same for every 40'HC open top container?

Detailed internal dimensions, roof opening clearances, tare weight and payload are finalized and certified according to the approved engineering drawing and CSC plate for each order.

What information should I provide when requesting a quotation?

To evaluate the required container specification, please provide:

● Cargo type

● Cargo dimensions

● Cargo weight

● Loading method

● Whether top loading is required

● Required vertical clearance

● Whether the cargo will extend above the container profile

● Required certification

● Quantity

● Destination

● Any special structural or accessory requirements
