The M1977 Common Bridge Transporter (CBT) is a modified M977 HEMTT Cargo truck equipped with a Load Handling System (LHS). The M1977 CBT was designed to support the Engineer Corps in transporting all bridging assets. The M1977 CBT loads, launches and retrieves the Ribbon Bridge, Improved Ribbon Bridge and Heavy Dry Support Bridge utilizing the Bridge Adapter Pallet, (BAP) and associated bridge erection boats utilizing the Improved Boat Cradle (IBC). The CBT is equipped with a winch to assist in retrieving the deployed equipment. The XM15 Bridge Adapter Pallet (BAP) is used to adapt the CBT for transport of Combat Engineer bridge equipment as mentioned above. When loaded, the BAP provides the necessary locks, rollers and guides to launch, retrieve and transport the bridge equipment. The BAP consists of the main frame and winch frame assemblies. The BAP is PLS compatible and is transloadable to/from the PLS trailer. The winch frame detaches from the BAP main frame and attaches to the CBT LHS. The winch frame utilizes the truck hydraulic power to winch the bridges during retrieval operations. The XM14 Improved Boat Cradle (IBC) is used to adapt the CBT for transport of the Combat Engineer Bridge Erection Boat (BEB). When loaded, the IBC provides the necessary locks, rollers and guides to launch, retrieve and transport the BEB. The IBC is PLS compatible, similar to the flatrack in design and is transloadable to/from the PLS Trailer.
