CAPE CANAVERAL, Fla. – Ground support equipment technicians prepare one of the jacking, equalizing and leveling, or JEL, hydraulic cylinders for removal from crawler-transporter 1 at the crawler transporter maintenance facility at NASA’s Kennedy Space Center in Florida. Sixteen new JEL hydraulic cylinders will be installed on CT-1 to increase load carrying capacity and reliability. The Ground Systems Development and Operations Program at Kennedy continues to upgrade CT-1 as part of its general maintenance. CT-1 could be available to carry commercial launch vehicles to the launch pad.

CAPE CANAVERAL, Fla. – Ground support equipment technicians assist as a crane moves a new jacking, equalizing and leveling, or JEL, hydraulic cylinder close for installation on crawler-transporter 1 at the crawler transporter maintenance facility at NASA’s Kennedy Space Center in Florida. New JEL hydraulic cylinders will be installed on CT-1 to test them for increased load carrying capacity and reliability. The Ground Systems Development and Operations Program at Kennedy continues to upgrade CT-1 as part of its general maintenance. CT-1 could be available to carry a variety of launch vehicles to the launch pad.

CAPE CANAVERAL, Fla. – Ground support equipment technicians monitor the progress as one of the jacking, equalizing and leveling, or JEL, hydraulic cylinders is lowered to the ground after it was removed from crawler-transporter 1. The work is being performed at the crawler transporter maintenance facility at NASA’s Kennedy Space Center in Florida. Sixteen new JEL hydraulic cylinders will be installed on CT-1 to increase load carrying capacity and reliability.
