Abstract: A vibration-proof construction method for preventing and reducing vibration around a structure which generates vibration or receives vibration includes construction work wherein a hard member having higher stiffness than the surrounding ground and a rubber elastic member are adjacently laid underground, around or directly underneath the building structure, thereby forming a hard layer and an elastic layer. The hard member is preferably concrete, hardening-treated soil, or iron material, and the rubber elastic member is preferably scrap tires or pulverized scrap tire material. Thus, a practical and excellent vibration-proof construction method is provided, whereby even better vibration-proof effects can be obtained, and which contributes to reduction in construction costs.

Abstract: A self-propelled road milling machine is equipped with a cooling system comprising a fan for drawing in air, a cooler, and a suction channel. The suction channel has a vent opening facing the cooler and an intake opening. In relation to the longitudinal axis of the road milling machine, the intake opening points to the side of the road milling machine, so that air is drawn in from the side. This results in significantly less dirt being sucked into the machine than when the suction channel is positioned in the direction of travel. In a preferred embodiment, the suction channel is formed in one piece with a liquid tank of the road milling machine. The liquid tank and suction system therefore form a modular unit, which can be easily installed on the chassis of the road milling machine.

Abstract: A system and method for inserting pre-cast concrete pile caps under wooden railroad bridges without removing essential load bearing rails, cross-ties, and stringers is disclosed. The system and method minimizes the time that the track is closed to normal rail traffic. The system and method uses recycled oil well drill pipes that are cast into pile caps so that female-threaded ends are flushed with an upper surface of the pile caps. Lifting rods have male threaded ends that are used with a multi-point lifting device that allows the pile cap to be slipped under the existing bridge in a number of small incremental steps utilizing the spaces between wooden bridge stringers.

Abstract: The present invention pertains to a mechanically actuated dock leveler with a mounting frame secured in a pit of a loading dock, and a deck assembly with a deck and extendable lip. A deck lift assembly biases the deck to move from a parked position to a raised position to activate a lip extension assembly. As the deck is “walked down”, the lip is extended and the lip extension assembly is deactivated in a controlled manner so that the deck and lip reach an engaged position against the trailer and are kept in place by a hold down mechanism. The deck assembly has a float housing with a slot for releasably engaging the lift assembly to achieve a range of float positions where the deck and lip rest on and float with the trailer as it is loaded and unloaded. The deck assembly has a durable combined lip lug and header plate hinge construction.
