S0 truss S0 truss steel mount structure connecting to the US lab. The S0 truss, (also called the Center Integrated Truss Assembly Starboard 0 Truss) forms the central backbone of the Space Station. It was attached on the top of the Destiny Laboratory Module during STS-110 in April 2002. S0 is used to route power to the pressurized station ...
STS-110 also delivered the Mobile Transporter (MT), which is an 885 kilograms (1,951 lb) (1,950 lb) assembly that glides down rails on the station integrated trusses. The MT was designed and manufactured by Astro Aerospace in Carpinteria, CA.
The four Main Bus Switching Units (MBSUs, located in the S0 truss), control the routing of power from the four solar array wings to the rest of the ISS. Each MBSU has two power channels that feed 160V DC from the arrays to two DC-to-DC power converters (DDCUs) that supply the 124V power used in the station.
The ISS, when completed, will consist of a set of communicating pressurized modules connected to a truss, on which four large pairs of photovoltaic modules (solar panels) are attached. The pressurized modules and the truss are perpendicular: the truss spanning from starboard to port and the habitable zone extending on the aft-forward axis

Control Moment Gyroscope (CMG) weight 600 lb × 4 units on Z1 Truss (two CMGs have been replaced, one by the STS-114 crew and a second by STS-118 crew). A CMG consists of a single-piece 25-inch diameter, 220-pound stainless steel flywheel that rotates at a constant speed of 6,600 rpm and develops an angular momentum of 3,600 ft-lb-sec (4,880 N ...
