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 the same machine.
Built for open-water heavy lifting, floating cranes combine structural strength, operational flexibility, and marine-certified engineering. Here are the five core features that define reliable performance.
The single-boom wire rope luffing mechanism keeps the hook path horizontal throughout the full radius range. As the boom angle changes, load height stays constant — eliminating the need for simultaneous hoisting corrections and allowing precise load placement directly over the target point on water.
Full 360° rotation under working load allows the crane to cover waterside and landside simultaneously from one fixed barge position. AC variable frequency drive control delivers smooth, stepless speed adjustment across the full slewing arc — critical for stable load handling on a floating platform.
The same crane handles both hook and grab attachments without structural modification. Hook mode delivers precise load control for general cargo and project lifting. Grab mode handles continuous bulk discharge of coal, sand, ore, and aggregates at high cycle rates.
Structural steel undergoes shot blasting and multi-layer anti-corrosion coating treatment rated for open marine environments. Key mechanical components are sealed and specified for continuous exposure to salt air, humidity, and wave splash — maintaining structural integrity without accelerated deterioration.
Designed and manufactured in compliance with CCS Code for Lifting Equipment of Ships and Offshore Facilities, with ABS, BV, and DNV certification available on request. Meets the documentation requirements for marine project approval, offshore deployment, and insurance compliance across global markets.

Offshore construction, salvage operations, and large-scale port development often push beyond standard specifications. Lifting capacity, working radius, pontoon dimensions, self-propulsion systems, and power configurations can all be tailored to match your specific project and water conditions. Contact our engineering team with your requirements and we’ll develop a specification from there.
Floating cranes operate where fixed infrastructure ends and open water begins. From offshore platforms to inland waterways, here are the five core application areas where floating cranes deliver results that land-based equipment simply can’t match.
Installing platform modules, subsea pipelines, and offshore structures requires heavy-lift capability at locations far from any fixed crane infrastructure. Floating cranes position directly at the worksite — no jetty, no fixed foundation required. High lifting capacity, stable pontoon design, and CCS/ABS certified structural integrity make them the standard choice for offshore oil and gas installation contractors worldwide.
Recovering sunken or grounded vessels demands lift capacity, precise load control, and the ability to work in open or restricted water conditions. Floating cranes handle the full salvage sequence — initial lift, controlled recovery, and vessel transfer to dry dock or scrapyard. Hook operation allows careful load management during recovery, while the 360° slewing covers the full working arc around the salvage site without repositioning the barge.
Installing precast bridge sections, pier foundations, and waterway infrastructure components requires heavy lifting directly over water at precise positions. Floating cranes bring the lift capacity to the exact installation point, eliminating the need for temporary land-based crane access roads or fixed lifting frames. The horizontal hook path during luffing keeps sections level throughout the placement sequence.
Building new port facilities, installing quay structures, and placing caisson foundations all involve heavy lifting in active marine environments. Floating cranes work alongside dredging and piling operations, handling large prefabricated components that arrive by sea and need direct placement without intermediate handling. Their mobility between work zones across a port development site keeps construction schedules moving.
At ports and terminals without fixed unloading equipment, floating cranes fitted with grab attachments handle bulk cargo discharge directly from vessel to barge or quayside storage. Coal, ore, grain, and aggregates move efficiently without requiring permanent terminal infrastructure — making floating cranes a practical solution for developing port markets and temporary cargo handling operations.
If you manage a marina, boatyard, or naval facility, you already know the pain: vessels stuck in the water waiting for maintenance, slipways that damage hulls, and cranes that simply weren’t built for boats. A marine travel lift solves all three problems in a single machine. It lifts, moves, and launches vessels safely — without fixed rails, without hull damage, and without slowing down your yard. This page covers everything you need to evaluate a marine travel lift: what it does, where it works, what makes ours different, and the full technical specs. If you are ready to specify a unit, our engineering team responds to enquiries within 24 hours. Product Description A marine travel lift — also called a boat travel lift, mobile boat hoist, or self-propelled boat hoist — is a rubber-tyred gantry crane designed specifically for vessel handling. The portal frame straddles the boat in the water. Polyester slings are positioned under the hull. The vessel is then lifted clear and driven anywhere on land. No rail tracks. No fixed infrastructure. Just one machine that handles haul-out,…

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 —…
