From an article in Port Technology:

The Port of Los Angeles has announced that the world’s first zero-emission top handles are now being used in daily operations at the Everport Container Terminal.

In a statement, the Port said the handlers were designed an built by Taylor Machine Works, a leading heavy-duty equipment manufacturer and the largest supplier of top handlers in service at the Port.

“We are doing everything possible to advance commercially feasible solutions to meet our goal of transitioning all cargo-handling equipment to zero emissions by 2030.”

Also known as top picks, top handlers are off-road vehicles with an overhead boom for loading containers weighing up to 100,000 pounds onto lorries and trains, unloading them, and stacking them on terminals between pickups and deliveries.

“We are pleased with performance results that we are receiving from drivers, mechanics and Everport management as the equipment is tested daily in real-world conditions,” said Port of Los Angeles Executive Director Gene Seroka. 

Additionally, drivers and mechanics are providing input on the maneuverability, noise level and safety of the equipment.
