Core+ stability
An effective system to keep the load more stable at higher speeds.
GH’S SOLUTION: Core+ Stability
- Effective for both trolley travel and crane travel.
- Effective to reduce sway due to both acceleration and braking.
- Touch-screen: Easy configuration and crane monitoring (power consumption, alarms, system faults).
- Easy to retrofit existing cranes. The CORE+ unit is affixed to the electrical panel door.
Advantages
Higher speed + Better accuracy = Increased Productivity and Safety
Hassle-free for operator: System reduces sway automatically.
How it works
Inputs from VFDs
CORE+ STABILITY continuously receives following inputs from VFDs:
- Commands from operator (accelerate / decelerate).
- Actual speeds (hoisting, trolley travel and crane travel).
- Vertical position of hook (given by the hoisting motor encoder).
Built-in exclusive Algorithm
Algorithm determines, based on above inputs, optimal acceleration / deceleration rates.
Instructs how to move
Core+ Stability instructs VFDs how to perform the movement.

Technical details
Bi-directional communication between CORE+ and the VFDs for hoisting, trolley travel and crane travel. Connection via CANopen fieldbus. Software is Upgradable via included USB port. Requires VFDs for all 3 movements, and hoisting motor encoder. Does not require expensive or failure-prone sensors. Maintenance-free. Open-loop control: will not detect / correct sway due to external factors. Automatically disconnects at low-speed motion to ease load positioning. System can be easily connected/disconnected (using touchscreen or optional remote control).
