GH Under Running Electric Hoists
GH under running electric hoists are configured for under-running cranes in multiple configurations. Under-running bridge cranes, also known as under-hung cranes, have a user-friendly design with wheels supported by the bottom flange of the runway beam. These cranes are designed for capacities under 10 tons and are typically ceiling-supported for maximum floor space utilization.
Under-running cranes maximize the hook-end approach of the hoist due to the bridge beam being located under the runways. They are ideal for facilities lacking vertical clearance and are typically configured in a single girder design for lighter service and lower-capacity applications, but can be built in custom configurations.
Products
Low-headroom hoists
Low-headroom hoists are perfect for using in the small under-beam space in single-girder cranes. Choose between flat or angled wheels to suit your bottom flanges and running profile, to improve performance and increase the life of your hoist.
Standard-headroom hoists ready for curves
This hoist is designed for applications that involve moving loads along curved paths and changes in direction. Choose between flat or angled wheels to suit your bottom flanges and running profile, to improve performance and increase the life of your hoist.

With the GH Core Box you will improve your crane’s performance with unparalleled control using our electronic load limiter, efficient hoist motor management, and prevention of over-temperature incidents. Gain valuable insights into your crane’s operations through comprehensive monitoring, including detailed operational data and incident logs. The Core Box goes beyond conventional monitoring by communicating parameters via a cellular network to GH Realtime, our proprietary data platform. Access advanced usage and maintenance services through the GH CRANES Customer Portal, providing real-time information on your crane’s operation.
How It Works:
Data Reception: Core Box gathers data from load cells, VFDs, and thermal sensors of the motors.
Processing Power: Core Box efficiently processes and records operating parameters and detected errors for insightful analysis.
Data Transmission: Transmit lifted load and SWP data to displays or radio controls, providing real-time information.
Connectivity Beyond: Utilize cellular network connectivity to seamlessly communicate with GH CRANES’ proprietary platform for advanced services.
Advantages:
All-in-One Integration: Enjoy the convenience of having Control, Monitoring, and Connectivity seamlessly integrated into a single device.
Accessory Connectivity: Connect to accessories such as Displays and Radio Controls for continuous monitoring of crucial data like Lifted Loads and Safe Working Period (SWP).
Non-Intrusive Connectivity: Communicate via 3G/4G networks, ensuring that the Core Box doesn’t interfere with your internal network.
Universal Compatibility: Retrofit Core Box to other crane brands, enabling monitoring and SWP calculation without disrupting their existing operation.
