A 49-year-old man was killed Monday when he was pinned between two delivery trucks while trying to transfer items from one to the other at a school for Jewish girls in Queens, cops said.

The two rental Ryder trucks were at 124-50 Metropolitan Avenue trying to make the transfer around 5 a.m. when the driver of one of the trucks backed up to the rear of the second truck, crushing victim Florentino Cruseno Morales, cops said.

EMS rushed him to Jamaica Hospital Medical Center, where he was pronounced dead.

The building where the trucks were is the address of Bais Yaakov Academy For Girls. At least one of the trucks was being rented by a company called Best Value Kosher Foods Corp., cops said. A voicemail message left for the company wasn’t immediately returned.

The NYPD Highway District’s Collision Investigation Squad determined the male was standing between the two rental trucks, attempting to transfer items from one truck to another.

“The male was pinned between both vehicle, and sustained severe body trauma,” the NYPD said. “Both vehicle operators remained at the scene and the investigation remains ongoing.”
