Enerpac introduces the new ETR Electric Trolley for moving heavy structures and assemblies between production stations, and during logistics handling, as a more operationally efficient alternative to traditional skidding methods. The Enerpac ETR-Series Trolley System comprises electrically driven trolleys which can carry heavy loads horizontally along a fixed, guided track system. With a 500kN (50-ton) and 1000kN (100-ton) capacity per trolley, load movements are more stable due to the continuous movement and ability to precisely control travel speed including acceleration and deceleration, offering a clean operation.
The trolley system is a safe and efficient method to move sensitive equipment and assemblies through production stations. It is suited to repetitive movements and can be easily configured to accept a wide variety of load configurations. Moreover, traveling on guided low-profile tracks with controlled synchronisation eliminates risks of moving large loads at overhead height.
A typical ETR-Series system includes 4 trolleys, 2 tracks, and 1 controller. It operates at speeds up to 50 m/hour (164 ft/hour) loaded travel speed and 100 m/hour (328 ft/hour) unloaded/reset speed. The Trolley System provides automatic synchronisation of traveling with an accuracy of 10mm (0.39 inch). An operator has the ability to combine up to eight trolley units synchronised together.
Wireless radio control comes as standard. Enerpac Trolley Systems are controlled by an inverter which allows speed to ramp up smoothly, maintain continuous movement and slow down smoothly preventing hard starts and stops. The standard control panel includes software with pre-programmed ramp up and down speeds. Additional features and benefits include high side load resistance, and high capacity per mechanically locked, trolley point. The Enerpac ETR is readily expandable and easy to transport and set up, while hydraulic lifting and support for more complex structures is optional.
