APL Limited purchased 12 Noell machinery-on-trolley cranes in the mid-1990s for their Port of Los Angeles Pier 300 terminal. The cranes were rated for 50 LT and have a 50’ backreach.
The backreach for all cranes was extended 28’ for storing hatch covers. The original girder was sufficiently long to accommodate the additional 28’ backreach.
Liftech designed girder reinforcing and a cantilever truss to mount the festoon and walkways. The original festoon backreach structure and access platforms were reused on the new truss. The modified crane met the stability requirements.
