About

The Top Cable Mast (TCM) is a specialized piece of ground support equipment intended for the crucial task of connecting electric lines to an Interorbital Launch Vehicle (ILV) instrument bay and subsequently breaking them out before the launch sequence. This metal structure is composed of a basement and a rotary frame. The basement houses the hydraulic and electric equipment necessary for the lifting and lowering operations of the rotary frame. Electric cables are routed along the rotary frame, and at its apex, a couplers-removing mechanism is integrated. The product was released in 2008 and boasts a guaranteed service life of 10 years. While it does not have flight qualification, it offers the possibility of adaptation to meet specific customer requirements. The estimated production time is 24 months, with an additional 5 months for delivery.
