SYNCHRO Easier and safer handling of large loads using 2 hoists GH’S SOLUTION: CORE+ SYNCHRO •Automatically keeps relative distances between hooks. Both horizontally and vertically. •Works with 2 hoists of same or different capacity, operating in same crane. •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. No need to make manual adjustment of relative position between hooks •Hassle-free for operator: maintains relative positions automatically. •Minimal sensor requirement. Increased Productivity and Safety. 1/•CORE+ SYNCHRO continuously receives following inputs from VFDs: - Commands from operator (accelerate / decelerate). - Actual speeds (hoisting, trolley travel and crane travel). - Vertical position of each hook (given by the hoisting motor encoder). •Relative distance between trolleys (given by the laser rangefinder). 1/ Inputs from VFDs and laser 2/ Built-in exclusive Algorithm Algorithm determines, based on above inputs, optimal acceleration / deceleration rates. CORE+ SYNCHRO 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, incremental encoder at each lifting motor, and 1 laser rangefinder. - Does not require expensive or failure-prone sensors. Maintenance-free. - Closed-loop control: Maximum error in lifting 10mm. Maximum error in cross travel 50mm. - Works with 2 hoists in the same crane. - System can be easily connected/disconnected (using touchscreen or optional remote control).
