Portal Cranes: Industrial Heavy-Duty Portal Solutions
We are the UK’s foremost structural engineering authority specialising in the bespoke design, manufacture, and installation of extreme-duty portal cranes.
When your operations demand serious muscle, "standard" equipment won't cut it. You need a lifting solution that doesn't just move weight—it drives your entire production timeline. Our Portal Cranes (Gantry Cranes) are engineered for the industries that build the world: shipyards, rail hubs, heavy manufacturing, and massive stockyards.
Whether you are looking to bypass the structural limitations of an existing building or you need a freestanding lifting powerhouse for an outdoor yard, our portal cranes deliver unmatched strength, surgical precision, and a relentless ROI.
What is a Portal Crane?
A portal crane gets its name from its structural shape, resembling a massive "portal" or doorway. Much like a Goliath crane, it features a heavy-duty horizontal bridge supported by towering A-frame or box-section legs that travel along ground-level rail tracks.
Because the structure is entirely self-supporting and spans massive widths, vehicles, trains, and articulated lorries can drive directly through the portal. This makes it the definitive, high-speed lifting solution for outdoor logistical hubs where erecting a supporting building is structurally impossible or financially unviable.
Why Our Cranes Outperform the Competition
We don't just build cranes; we eliminate downtime. Every feature is designed to keep your hook moving:
Millimetre Precision
Equipped with high-end Variable Frequency Drives (VFDs), our cranes eliminate "load swing." You can position a 50-ton component with the delicacy of a finger touch.
Built for the Elements
Our outdoor units feature IP66-rated electrical enclosures, galvanised walkways, and marine-grade paint finishes. Rain, dust, and corrosion don't stand a chance.
Safety as Standard:
From laser-based anti-collision sensors to automatic storm anchors and rail clamps, we protect your most valuable assets: your people.
Rapid Maintenance Access
We design with the technician in mind. Integrated service platforms and easy-access motor mounts mean "maintenance" is a quick check-up, not a day-long shutdown.
Stop Struggling With Capacity. Start Leading
An inefficient lifting setup is a bottleneck that costs you money every hour. Upgrade to a structural solution that scales with your ambition. Our portal cranes aren't just tools—they are the heartbeat of a high-output facility.
Ideal Environments for Portal Cranes
Our bespoke portal cranes act as the essential structural backbone for the UK’s most demanding, high-throughput sectors:
Rail Freight & Intermodal Terminals
Rapidly lifting and stacking fully loaded shipping containers straight from rail cars onto waiting articulated lorries.
Ports and Commercial Dockyards
Providing the monumental lifting power required for bulk cargo handling, shipyard block assembly, and dry dock maintenance.
Heavy Civil Precast Yards
Hoisting immense precast concrete bridge spans, massive architectural panels, and subterranean drainage systems across vast outdoor staging areas.
Steel Stockholders & Scrap Processors
Moving excessively heavy steel billets, massive I-beams, and bulk materials safely across expansive, active yards.

What is the difference between a portal crane and a gantry crane?
In the UK heavy engineering sector, the terms are often used interchangeably. However, a "portal crane" specifically highlights the architectural shape of the machine—a massive structural "portal" or doorway. They are designed with exceptionally wide spans and high clearance so that articulated lorries, freight trains, and heavy plant machinery can drive directly through the legs and underneath the lifting bridge for rapid loading and unloading.
What is the maximum lifting capacity of a portal crane?
At GoliathCranes.co.uk, our bespoke manufacturing capabilities mean we are not limited by standard catalogues. We engineer and build portal cranes with Safe Working Loads (SWL) starting at a highly agile 10 tons, scaling all the way up to mega-capacity 1,000-ton titans. Your crane's exact capacity, span, and lifting height will be custom-engineered to perfectly match your facility's operational demands.
How are large outdoor portal cranes powered across long travel distances?
Powering a massive moving structure across a multi-acre outdoor yard requires robust, weather-proof engineering. Our heavy-duty portal cranes are typically powered using highly advanced, motorised cable reeling drums that automatically deploy and retract heavy-armoured power cables as the crane moves. For specific site layouts, we can also integrate heavy-duty enclosed conductor bar systems (busbars) to deliver safe, consistent 3-phase power.
Do I need bespoke ground foundations to install a rail-mounted portal crane?
Yes. Because portal cranes carry monumental dynamic loads (the immense weight of the steel crane itself plus payloads up to 1,000 tons), standard concrete yards are insufficient. During our initial consultation, our structural engineers will conduct a rigorous site survey and specify the exact reinforced concrete footings and heavy-duty embedded steel rails required to safely support your new heavy-lift infrastructure.
What are the legal compliance and safety requirements for outdoor portal cranes in the UK?
All portal cranes operating in the UK must strictly comply with LOLER (Lifting Operations and Lifting Equipment Regulations) and PUWER (Provision and Use of Work Equipment Regulations). For outdoor portal systems, safety compliance also dictates the use of environmental fail-safes. We equip our cranes with electronic anemometers (wind speed sensors) to warn operators of dangerous gusts, alongside automated storm anchors and rail clamps that physically lock the crane to the ground during severe weather.
