Highline Docks by Webb-Stiles

What is a Highline Dock?

A Highline Dock is a free-standing, self-supporting platform that supports non-powered conveyor systems for heavy cargo handling. Its primary role is to create an elevated holding area for large, palletized loads—specifically military-standard 463L pallets—while enabling efficient storage, staging, and transfer operations above floor level.

To achieve this, the system features a heavy-duty metal frame fitted with gravity roller conveyors. Forklifts or K-loaders place cargo onto the dock, which then moves across roller lanes for staging until ready for transfer. Although non-powered, the dock’s conveyor layout ensures smooth manual transfers while reliably handling significant weight.

In many facilities, ground space is limited but material flow cannot be interrupted. Highline Docks provide a solution by utilizing vertical space, enhancing staging capacity, and improving equipment access. Consequently, they are well-suited for military logistics and air cargo operations handling pallet trains, containers, or airdrop platforms.

Furthermore, each dock configuration is modular and scalable. Systems can be built to accommodate multiple pallet orientations—such as wide-edge or narrow-edge leading—and are compatible with various loading equipment. In practice, adjustable support frames ensure proper installation on uneven surfaces, delivering flexibility across diverse operational needs.

Types of Highline Docks

Model 555 – Front Entry

How it works
Model 555 allows pallets to be loaded and unloaded directly from the front end of the dock. Because side access is not available, this model offers a straightforward solution for linear material flow.

Unique features
With a simplified frame design focused on dedicated front access, Model 555 is best applied in environments where facility space or equipment layout limits the possibility of side entry. Therefore, it remains an efficient choice when simplicity and space constraints drive design decisions.

Best for
Operations with clear front-loading zones where side entry is unnecessary.

Model 556 – Single Side Entry

How it works
Model 556 provides both front and side entry points. A specialized end section with reinforced supports manages the added forces that occur during side-loading operations.

Unique features
In addition to front access, Model 556 introduces side entry capability, supported by an extra center frame for added stability. As a result, this configuration ensures structural integrity when pallets are transferred from the side.

Best for
Facilities that require flexible side-loading options without fully committing to dual side entry setups.

Model 557 – Dual Side Entry

How it works
Model 557 features two nine-foot end sections with custom side cutouts. These enable pallet loading and unloading from either side, as well as from the dock’s end. Additional support frames are included to handle side-loading forces effectively.

Unique features
Designed for maximum accessibility, Model 557 supports simultaneous side and end loading. Consequently, its enhanced support frames maintain stability under the demanding forces of multi-directional material flow, ensuring reliable performance in complex environments.

Best for
High-traffic facilities where multi-directional access is essential for maintaining operational efficiency.

How Highline Docks are Engineered

At Webb-Stiles, designing a Highline Dock is never about picking from a catalog. Instead, it begins with understanding the unique challenges of your facility and engineering a solution that fits your operation perfectly. Our process always starts by asking the right questions.

Material Flow & Load Requirements

First, we evaluate the types of cargo—463L pallets, pallet trains, containers, or platforms—and how they move through your operation. Factors such as load capacity, handling methods, and equipment interaction directly influence system design.

Facility Layout & Space Constraints

Your available floor space, vertical clearance, and traffic flow all shape how the dock integrates into your facility. Access points for side and end loading are configured to align with your workflow. At the same time, we design the overall footprint to enhance—not disrupt—existing operations.

Installation Environment & Surface Conditions

Site-specific factors like surface slope, material type, and ground stability are essential to finalizing the design. To address these, we select adjustable support frames, sliding base plates, and durable material finishes that ensure reliable long-term performance.

Operational Safety & Long-Term Performance

We go beyond basic load ratings by considering dynamic forces from forklifts, personnel access requirements, and maintenance needs. Webb-Stiles engineers design catwalks, pallet stops, and guide rails to withstand daily use while maintaining operational safety.

Throughout every project, our in-house design, fabrication, and installation teams lead the process from start to finish. This hands-on approach ensures your Highline Dock is built specifically for your needs—not forced into a generic mold.
