Abstract:
1. A vibration-damping support device comprising: a mount which is to be attached to an engine of a construction machine and has an elastic member for absorbing vibrations of the engine; a support member which supports the mount thereon and is fixedly secured on a frame of the construction machine; and stoppers for preventing an excessive deformation of the elastic member in an up-and-down direction under the vibrations, the elastic member being formed of a pair of truncated cones that are arranged symmetrically about a horizontal plane, wherein: one of the stoppers, which is fixedly secured on an upper side of the support member, is: (i) arranged so as to come in contact with a mounting platform of the engine under vibrations of the engine, (ii) positioned with one end fixedly secured on the upper side of the support member close to a base portion of a large-diameter of one of the truncated cones which is located on the upper side; and (iii) arranged integrally with the support member forming a certain space gap between the mounting platform of the engine and the support member, such that when vertical vibration of the engine becomes larger, the mounting platform of the engine comes into contact with the stopper arranged integrally with the support member without occurrence of an interference between the elastic member and the stopper and excessive deformation of the elastic member is prevented.
