FIELD: small-size shallow draft river transport facilities for transportation of small lots of agricultural cargo in shallow waters. SUBSTANCE: push-train consists of cargo sections having pointed bow and recess in stern which may enter one another and may be operated in column and in multi-line trains. Fore portion of pusher is received by recess of end section. Located before two-line train is self-controlled attachment with engine and cargo hold. This attachment is used as fairing and effective thruster when underway. In forming and breaking-up the train, attachment is used as pusher. Vessels of train are at rather close contact relative to each other which ensures good propulsive quality at minimum power. Connection of vessels at ends provides for adequate freedom for their motion in case pitching of up to 15 deg at retained longitudinal strength and rigidity of entire train. EFFECT: low cost of unified cargo sections equipped with hatch closures. |
