YFM Engine Room Overhead Crane is engineered to tackle the toughest lifting challenges in marine engine rooms. Designed for precision, durability, and safety in confined spaces, it ensures seamless handling of engines, generators, and heavy components during maintenance and repair operations. Trusted by shipbuilders and fleet operators worldwide, this crane is your ultimate partner for efficient vessel operations.
As a key lifting equipment in marine engine rooms, the components of Engine Room Cranes vary according to their types (such as overhead cranes, gantry cranes, jib cranes, etc.), but the core structures share universality.
Metal Structure System
Main Girder: Made of high-strength steel (e.g., Q345B), it must meet bending and torsional strength requirements.
End Girder: A transverse component connecting main girders on both sides.
Legs: Support structures for gantry or cantilever cranes.
Running Mechanism
- Trolley Travel Mechanism: A device driving the crane to move longitudinally along engine room rails.
- Crane Trolley Mechanism: Installed on the main girder to drive the hoisting mechanism for lateral movement.
Hoisting Mechanism
- Drum: Realizing lifting/lowering of heavy objects by rotating to retract/extend wires.
- Wire Rope: Must comply with marine industry standards (e.g., ISO 4308).
- Hook Block: Hooks must have safety clasps to ensure lifting safety.
- Motor & Brake: Motor paired with an electromagnetic brake to prevent load dropping when power is cut off.
Electrical Control System
- Control Cabinet: Adopts waterproof and dustproof designs (e.g., IP54 protection rating).
- Operation Device: Buttons are ergonomically arranged with clear action indicators (e.g., ↑↓←→).
- Power Supply: Powered by slide contact lines or cable reels, mostly at 380V/60Hz to match marine power grids.
Safety Protection Devices
- Load Limiter: Automatically cuts off hoisting power when the load exceeds the rated value to prevent overloading (accuracy ≥±5%).
- Limit Switches: Include lifting height limit (to prevent hook overtravel) and travel limit (to avoid crane collision with obstacles).
- Buffer: Absorb collision energy and reduce impact.
- Acoustic-Optic Alarm: Emits warning signals during operation to alert engine room personnel.
Auxiliary Components
- Rail & Foundation: Rails typically use QU-type special steel for cranes.
- Lubrication System: Regularly supply oil to friction parts like wheel bearings and reducer gears to extend equipment life.
- Rain & Dust Covers: Protective covers to shield electrical components and transmission parts from corrosion.
Through the above modular design, engine room cranes can achieve efficient and safe lifting operations while meeting the strict regulations of the shipping industry (such as certification requirements of classification societies like ABS and DNV).

Selection Considerations
Hoisting parameters should be determined based on engine room height, span, and maximum lifting weight (e.g., 20t/32t).
Explosion-proof cranes are suitable for special scenarios like oil tankers and must comply with the IEC 60079 explosion-proof standard.
