The latching principle involves control from a pendant which, when selected, will activate the spring load locking pin at stand-by position while the crane travels at slow speed. At this time, the operator moves the crane to the shunting station where the passive side of the latch will be engaged. Both end-stoppers will then be opened and ready for hoist crossing.
Thereafter, the system will deactivate the spring loading locking pin upon unlatch selection from the pendant control. The engines will be transferred from bay to bay and latched again to a monorail that leads to the test cell for their engine test run.
The order also included 76 manual trolleys from Verlinde. Anti-collision sensors will be fitted to cross-check the alignment of the latching devices before the hoisting units have the green light to move through the monorails.
The client requested to remain unnamed. The project is scheduled for completion in September 2008.
