The use of top-loading railcars and trucks remains an efficient and economical solution in a myriad of scenarios. A crucial component of this process is an optimally configured loading system.

A competent loading system should have ample horizontal range, enabling it to access the most remote compartment without necessitating vehicle repositioning. Furthermore, it needs sufficient vertical flexibility and adequate drop-pipe lengths to cater to vehicles of varying heights.

With thoughtful design, a top-loading system can fulfil these requirements whilst also offering protection. Moreover, top-loading arms are versatile instruments that can be utilised for a plethora of applications, such as tight-fill, vapour recovery, and marine operations. They can be specifically adapted for these tasks through the incorporation of specially engineered components, like vapour plates, tapered hatch plugs, and inflatable hatch seals.

In addition, our top-loading arm designs can be supplied with a broad range of valves, fittings, and instrumentation equipment to accommodate specific needs.

Types of Top Loading Arms we Supply

• Fixed Reach Style Top Loading Arm: This straightforward arm, designed for top-loading applications with a fixed vehicle range, integrates three swivel axes for versatile movement, accommodates internal or external valve placement to facilitate loading and reduce dripping of viscous products, and offers customisation options for tight filling or closed loading with additional swivel axes, drop hose, and necessary outboard coupling, union, or fitting.
• Scissor Style Top Loading Arm: Designed primarily for loading and unloading tank trucks within a reach under 120″, this arm, optimal for top-loading installations requiring a flexible range, features a 360-degree horizontally rotating auxiliary arm for ample spotting allowance.
• Unsupported Boom Style Top Loading Arm: Boom style loading arms, offering extensive reach, unmatched flexibility, and simple operation, are ideal for applications requiring variable reach, especially with larger sizes and heavier outboard elements, and can include a support section for enhanced reach and weight handling, while also offering a practical, compact storage solution by folding back against the loading platform.
• Supported Boom Style Top Loading Arm: Boom type loading arms, ideal for tasks requiring variable reach and known for extended reach, unmatched flexibility, and straightforward operation, are particularly suitable for handling large sizes and hefty external elements, can be supplemented with a support segment to enhance reach and weight handling, and feature collapsible design against the loading platform for efficient, space-saving storage.
• Slide Sleeve Arm A-32-F: The slide sleeve model loading arm, perfect for top loading petroleum products in smaller plants, features a telescopic sliding sleeve for effortless drop tube positioning, offers a budget-friendly solution, but is limited to flow rates of up to 15 ft/sec to avoid overextending the inner tube.
