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.
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 so that a pair of hatch cover leaves can be lifted, swung clear and stacked in one pass.
It can be customized in terms of tonnage, span, height, drive method, and control system to meet specific customer requirements.
A hatch cover gantry crane has several design features in structure and configuration.

Note: dimensions above reflect a representative general-arrangement drawing for a twin-hook model and vary by contracted capacity, hatch coaming length, and vessel class rules. A project-specific GA drawing is issued for confirmation before production.
Haitai Crane’s hatch cover gantry crane can be applied to these scenarios:
Production has covered a range of real deployed models rather than a single catalog unit:
Pre-shipment inspection has included overseas buyer teams attending factory acceptance testing on-site before loading, with the crane’s rated SWL and manufacturer markings stenciled directly on the main girder for verification against the contract and classification documents.
Please confirm the following before we issue a formal quotation and GA drawing:
| No. | Confirmation Item | Buyer Input |
|---|---|---|
| 1 | Vessel type / IMO No. (new-build or retrofit) | |
| 2 | Hatch coaming length, width and existing rail gauge | |
| 3 | Required lifting capacity per hook and number of hooks | |
| 4 | Hatch cover panel weight, quantity and lug/pad-eye spacing | |
| 5 | Required lifting height and travel distance | |
| 6 | Power supply (voltage / frequency / phase) | |
| 7 | Preferred control mode (cabin / pendant / wireless) | |
| 8 | Classification society required (CCS / BV / ABS / RINA / other) | |
| 9 | Delivery port and Incoterm (FOB / CIF / CFR, etc.) | |
| 10 | Other accessories (festoon cable, spare hoist motor, spreader type) |
Selecting the wrong ship deck crane creates problems that follow you for the vessel’s entire operational life. Inadequate lift capacity, poor outreach, or a crane not certified by your classification society — any of these can delay port clearance, increase operating cost, or create liability exposure in the event of an incident. This page gives procurement managers, ship owners, and shipyard purchasing teams a clear, practical overview of what to look for when sourcing a ship deck crane. We cover equipment types, key technical parameters, certification requirements, and what distinguishes a reliable supplier from a risky one. HT crane manufacture and export ship deck cranes across a full capacity range — and we back every unit with classification society certification, factory load testing, and long-term spare parts support. What Is a Ship Deck Crane? The Basic Function A ship deck crane is a rotating lifting device permanently mounted on a vessel’s deck. It handles cargo loading and unloading at ports where shore-based equipment is unavailable or insufficient. It also supports deck operations, equipment transfers, and maintenance lifts during voyage. Vessel…
A marine arm crane is one of the most versatile pieces of deck equipment a vessel can carry. Unlike a straight-boom deck crane, a knuckle boom or articulated arm crane folds compactly when not in use, reaches over obstacles, and positions loads with precision that a fixed boom simply cannot match. For ship owners and procurement teams evaluating deck crane options, the choice between a straight boom and an articulated arm crane often comes down to one question: does your operation require the crane to work in confined spaces, reach below deck level, or handle irregular load positions? If yes, a marine arm crane is almost certainly the right choice. This page covers what marine arm cranes are, where they are used, what the key specifications mean, and how to evaluate suppliers before committing to a purchase. What Is a Marine Arm Crane? The Core Design Concept A marine arm crane — also called a knuckle boom crane or articulated marine crane — uses two or more boom sections connected by hydraulic-powered knuckle joints. This articulation allows the crane to…
A boat jib crane is a marine-grade lifting solution designed specifically for docks, marinas, shipyards, and offshore platforms — where saltwater corrosion, confined space, and dynamic loads demand equipment built to a different standard. HaiTai Crane’s boat jib cranes deliver 0.5 to 20 tons lifting capacity, 180° to 360° rotation, and full C4–C5 marine corrosion protection from structural steel to electrical enclosures. Quick Reference: Boat Jib Crane Specifications Parameter Standard Range Custom Available Lifting Capacity 0.5 t – 20 t Up to 50 t on request Jib (Boom) Length 3 m – 10 m Up to 15 m Rotation Angle 180° / 270° / 360° Configurable Lifting Height 3 m – 12 m Customizable Hoist Type Electric chain / Wire rope Manual available Control Mode Push-button / Radio remote Cabin option Corrosion Protection Hot-dip galvanized + marine paint C4/C5 ISO 12944 Mounting Type Column / Wall / Dock-embedded Floating dock option Certification CE, ISO 9001:2015 CCS / BV on request Power Supply 380V / 50Hz (customizable) Global voltage supported What Is a Boat Jib Crane Structure and Operating Principle A…
