A heavy-duty boat jib crane engineered for marine and shipyard operations — delivering up to 40T capacity, 360° rotation, and radio remote control in one reliable lifting solution.
Our boat jib crane is a freestanding pillar crane designed specifically for marine and shipyard lifting operations. Available in 20T, 30T, and 40T capacities, it offers boom lengths up to 10,300mm and lifting heights up to 7,450mm — built to reach across and into most commercial vessel profiles.
This boat jib crane is the go-to solution for shipyards, dry docks, port maintenance zones, and vessel repair facilities. In these environments, fixed overhead cranes can’t always reach where you need them, and mobile equipment struggles with stability near water. It fills that gap — a fixed, high-capacity crane that covers a wide working radius without taking up excessive floor space.
360° rotation and radio remote control come standard, giving operators precise load control from a safe distance. Optional galvanized structure protects against saltwater corrosion for long-term coastal use.


Shipyard Assembly & Maintenance Handling heavy structural components, engines, and hull parts during vessel construction and scheduled maintenance cycles.
Dry Dock Operations Precise load positioning in confined dry dock environments where overhead cranes cannot reach and mobile equipment lacks stability.
Port & Dock Facilities Reliable dockside lifting for routine equipment handling, cargo positioning, and maintenance tasks at busy commercial port facilities.
Vessel Repair & Refit Yards Supporting overhaul and refit operations where technicians need consistent, controllable lifting access across the full vessel profile.

A: There are several types jib crane, pillar mounted, wall mounted, wall travelling, portable type and articulating type. Your may tell us your working condition, lifting material, arm length and lifting height. We could offer you a satisfying solution to meet your needs.
A: The cantilever length needs to be determined based on the layout of work space and lifting range (e.g. a long and narrow workshop may require a 10-meter cantilever jib crane).
Insufficient rotation radius may lead to limited operation, and needs to be selected in combination with on-site measurement data.
Installation is quick and simple, usually completed within a few hours without special tools.
