A. The Challenge

Industrial trailer purchasing is traditionally a slow, specification-heavy process. The buyer knows what they need. But communicating that specification to a manufacturer typically involves phone calls, emails, PDF spec sheets, and multiple rounds of clarification. For Hulck, this created two problems. First, the sales team spent significant time on the front end of every enquiry. Second, prospects who were still in the research phase. They could read spec sheets and browse the gallery, but they couldn't see their trailer configured to their requirements.

B. What We Built

The configurator lives at hulck.com as an integrated page within the existing WordPress site. It presents the full range of trailer configuration options alongside a real-time 3D preview.

23+ Configurable Attributes

Industrial trailers aren't like consumer products with a handful of colour options. Hulck's configurator exposes the full depth of their manufacturing capability:

• Dimensions — length, width, and height, defining the trailer's physical footprint and load area
• Load capacity — from standard to heavy-duty ratings
• Floor type — wood, aluminium, steel tread plate, roller systems, or no floor — each with different weight, durability, and use-case characteristics
• Wheel material and tyre size — solid rubber, air-filled, super-elastic, or polyurethane — chosen based on the operating environment (indoor cleanroom vs. outdoor yard vs. port terminal)
• Steering system — turntable or kingpin (fusee), affecting manoeuvrability and load distribution
• Coupling type — how the trailer connects to the towing vehicle
• Walls and gates — configurable side walls and end gates for cargo containment
• Tarpaulin and cover systems — for weather protection and cargo security
• Rails and tie-down systems — for securing loads during transport
• Parking brake, lighting, reflectors — safety and compliance features
• Colour — frame and component colours to match corporate fleet standards
• Non-marking tyres — a specific requirement for cleanroom and indoor environments where floor marking is unacceptable

Every selection updates the 3D model in real time. The buyer sees exactly what they're specifying, not an abstract list of options, but a visual representation of the trailer they'll receive.

3D Preview with Screenshot Capture

The Expivi-powered 3D viewer renders the configured trailer from any angle, with 360° rotation and zoom. The buyer can inspect the floor surface, check the wheel configuration, verify the wall and gate arrangement. All from their desk, without a site visit or sales call.

WordPress and WooCommerce Integration

This was the core engineering challenge of the project. Expivi is a standalone platform with its own frontend and API. WordPress is an opinionated CMS with its own conventions for page rendering, form handling, and data management. Making the two work together seamlessly without breaking either system's expectations required careful integration work.
