Heavy lifting on water comes with problems that land-based equipment simply can’t solve. Fixed cranes need permanent infrastructure. Mobile cranes can’t reach offshore worksites. And standard barges don’t have the lift capacity for serious marine construction, salvage, or port development work. A floating crane solves all three — bringing certified heavy-lift capability directly to the worksite, wherever that happens to be. HT CRANE floating cranes are built to CCS standards and available with ABS, BV, and DNV certification. Custom lifting capacity, working radius, and power configurations are available to match your specific project requirements. If you’re looking for a floating crane for sale that’s certified, proven, and configurable, you’re in the right place. What Is a Floating Crane A floating crane is a heavy-lift crane mounted on a pontoon or barge, designed to operate directly on water. It requires no permanent shore infrastructure, making it the go-to solution for marine construction, salvage, offshore installation, and waterway projects where conventional cranes simply can’t reach. Most units support both hook and grab attachments, adapting to different cargo types and task requirements on…
Container terminals run on throughput. Every hour a vessel spends at berth waiting for cargo moves is an hour of revenue lost — for the shipping line, the terminal operator, and the port authority. The pressure to move boxes faster, handle larger vessels, and keep equipment running around the clock is constant and only increasing. A ship-to-shore crane is the front line of that operation. It’s the machine that determines how quickly a vessel is turned around, how many moves per hour the terminal can deliver, and whether the port can handle the next generation of Ultra-Large Container Vessels coming into service. What Is an STS Crane? An STS crane — short for ship-to-shore crane — is a large rail-mounted gantry crane positioned at the quayside of a container terminal. It lifts containers directly between the vessel’s deck and the dock, using a spreader bar that locks onto standard ISO container corner castings. The boom extends out over the vessel to reach across multiple container rows, then retracts when vessels need to pass. Lift height, outreach, and under-beam clearance are…
What Is a Portal Crane? If you work at a port, shipyard, or bulk terminal, you’ve almost certainly seen a portal crane in action. It’s the large slewing crane mounted on a fixed or rail-mounted base that covers both the water and land side of a dock without ever needing to move its foundation. The boom luffs up and down to reach different distances, while the upper structure rotates a full 360° — making it one of the most versatile heavy-lift solutions available. Depending on the job, it can be fitted with a hook for general cargo or a grab for bulk materials like coal, ore, and grain. HT CRANE’s slewing portal crane and portal boom crane series meet CCS, ABS, BV, and DNV standards — so whether you’re outfitting a shipyard or running a busy bulk terminal, there’s a configuration built for your operation. Key Features of Portal Crane Every port is different. Every cargo mix is different. portal cranes are built with the features that matter most — reliable slewing performance, flexible attachment options, and certified structural integrity…
If you handle heavy containers, steel structures, or oversized industrial cargo — and your site lacks fixed power infrastructure — a hydraulic straddle carrier is likely the most practical solution available. It lifts, travels, and places loads without needing overhead structures, rails, or high-voltage power supply. One machine. Full mobility. Minimal civil works. What Is a Hydraulic Straddle Carrier? The Core Concept A hydraulic straddle carrier is a self-propelled heavy lift vehicle. It straddles a load — lifting from below using a hydraulic spreader or lifting beam — and moves freely across the yard on rubber tyres. The entire lift-and-travel cycle is powered by an onboard diesel-hydraulic system. Unlike electric or cable-reel powered cranes, the hydraulic straddle carrier carries its own power source. This makes it fully independent of yard infrastructure. You can deploy it anywhere your surface can support the wheel loads — no fixed installation required. How the Hydraulic System Works The engine drives hydraulic pumps that supply pressurized fluid to the lift cylinders, drive motors, and steering actuators. All motion — lifting, lowering, travelling, and steering —…

A shipyard without the right gantry crane is not a shipyard — it is a steel fabrication yard with ambition. The gantry crane defines what a yard can build, how large a vessel it can handle, and how fast production moves from block assembly to launch. An undersized or poorly specified crane becomes the bottleneck that limits every other investment in the facility. Shipyard gantry cranes are among the most technically demanding lifting machines in any industrial sector. They span widths of 80–170 metres, lift loads of 100–3000 tonnes, and operate in a marine environment that subjects every structural and electrical component to continuous salt-air corrosion. Getting the specification right from the outset determines whether the crane serves the yard reliably for 30 years or becomes a source of unplanned downtime that disrupts the production schedule. Product Description What Is a Shipyard Gantry Crane? A shipyard gantry crane — also called a goliath crane, portal gantry crane, or shipbuilding gantry crane — is a large double-leg gantry structure that spans the full width of a shipbuilding berth, drydock, or block…

The hatch cover gantry crane is a rail-travelling box-leg gantry structure along bulk carriers’ and general cargo vessels’ hatch coaming, used to lift, shift and stack lift-away hatch covers. It is built as single or twin-girder frame with one or two independent electric hoists, runs on flanged wheels along coaming-top rails, driven by variable-frequency motors for smooth positioning in sea-state working conditions. Capacities range 5 to 40 tons, with single-hook or twin-hook (e.g. 2×12.5T), and CCS, BV, ABS or RINA classification is available on request. What Is a Hatch Cover Gantry Crane? A hatch cover gantry crane is dedicated marine deck-handling equipment, designed for opening, closing, hoisting, and maintenance of ship hatches, this compact structure is suitable for decks with limited space and frequent operation. Unlike a shore-based gantry, it is a marine deck crane: it must run on the ship’s own coaming rails, tolerate roll and pitch, resist salt-spray corrosion, and be light enough not to overload the deck structure while still handling covers that can weigh 5–40 tons apiece. The frame is either a single-girder gantry with one enveloping trolley/hoist, or a twin-girder gantry carrying two independently-driven electric hoists…
