FIELD: bridge erection and crossing equipment; pontoon parks.
SUBSTANCE: proposed mounting includes frame, transom board, cross-piece, spacer and two side members. Cross-piece is made in form of beam secured on force portion of pontoon by means of pin joint and provided with shaped bolts for securing on pontoon transom. Spacer is made in form of distance truss with lower and upper brackets supported by fore portion of pontoon and is secured to cross-piece by means of bolts; frame is connected with cross-piece by means of fork joint and is supported by spacer; articulated to each strut of frame is side member which may be fixed in working position; both side members are provided with plates to which transom board is secured. Besides that, struts of frame are provided with brackets and transversal couplings of side members are provided with lugs; brackets and lugs have two parallel holes each where axles and pins-retainers are fitted in skew-symmetric position relative to side member. Proposed device ensures motorization of pontoon and compact transportation due to folding of mounting in transportation position reducing volume by 3 times.
EFFECT: enhanced efficiency and reliability.
