The marine monorail overhead crane is a rail-mounted lifting device tailored for shipboard operation scenarios. It can be flexibly installed on the ceilings or elevated structures of spaces such as engine rooms, workshops, and warehouses.
Adopting a single-girder structure made of I-beam or H-beam steel, this crane allows its trolley and hoisting mechanism to travel horizontally along the girder, enabling efficient and precise material handling along a fixed path.
Components
--- for spaces such as ship engine rooms, workshops, and warehouses
The marine monorail overhead crane is made up of key steel components:
main girder, trolley, hoist mechanism (hoist unit), and rail support structure. Their respective functions are as follows:
Main Girder
The core load-bearing part of the crane provides essential structural support and foundation. Usually made of high-strength steel such as carbon steel, its material is chosen according to the crane's lifting capacity, material strength performance, and durability demands.
Trolley
A component that moves horizontally along the entire main girder. Fitted with an integrated hoist mechanism (hoist unit), it drives the lateral movement of loads and ensures precise positioning during lifting tasks.
Hoist Mechanism (Hoist Unit)
Installed on the trolley, it is responsible for vertical load lifting and lowering. Its rated lifting capacity can be flexibly configured for actual working conditions, covering both light and heavy-duty operational needs.
Rail Support Structure
Supported by elevated structures or similar components, it bears the weight of the main girder and ensures smooth movement of the trolley and hoist mechanism along the preset path.
