15 ton double girder crane - trolley mechanism
The trolley mechanism is the core component of a double girder crane and is responsible for moving the hoisting unit (hoist or trolley) horizontally along the main girder. It includes motor-driven wheel sets, gear reducers, brake systems and controls to ensure smooth, stable and precise operation under load.
The following are the main features of the European standard trolleys (also known as FEM/DIN type trolleys) used in double girder overhead cranes. These trolleys are designed according to European standards such as FEM, DIN and ISO, and have superior performance compared to traditional CD/MD hoist trolleys.
⚙️ 15 ton European-Standard Crane Trolley Features
Compact and Modular Design
Low headroom and compact dimensions maximize lifting height and save space.
Modular components for easy maintenance and upgrade.
Lightweight and High-Strength Construction
Trolley frame made of welded steel or precision-formed plates, ensuring strength with reduced dead weight.
High-Performance Hoisting Mechanism
Equipped with FEM-standard wire rope hoist or open winch type.
Hardened gears, precision bearings, and sealed gearboxes for long service life.
Variable Frequency Drive (VFD) Control
Both lifting and traveling motions can be VFD-controlled for Quiet and Stable Operation
Low-noise motors, optimized gear design, and cushioned wheel assemblies reduce vibration and sound.
Advanced Safety Systems
Includes overload limiter, upper/lower limit switches, thermal motor protection, overspeed protection, and emergency stop.
Intelligent Monitoring (Optional)
Optional smart control systems for fault diagnostics, maintenance alerts, and real-time monitoring (e.g., via HMI).
Customizable Configurations
Can be adapted for hazardous environments (e.g., explosion-proof), clean rooms, or high-temperature applications.
Energy Efficiency
IE3 motors and regenerative braking systems reduce energy consumption and improve efficiency.
