ABSTRACT:
A tiltable element, e.g. an operator's cab, is resiliently supported on a body frame by a plurality of pivotable mounting devices. Each device comprises a pair of parallel bracket members and a support element. The support element and the bracket members have coaxial openings therethrough with a generally cylindrical shaft positioned in the openings. The shaft has first and second externally threaded end sections and an intermediate section. The diameter of the first end section is greater than the diameter of the intermediate section so as to form a first shoulder therebetween. The opening in one bracket member has internal threads to matingly receive the threads on the first shaft end section. An annular shell has an inner diameter at least as large as the diameter of the intermediate shaft portion and less than the diameter of the first shaft end section. An annular resilient sleeve is mounted between and in contact with the annular shell and the support element. An annular spacer sleeve is loosely telescoped over the second shaft end and freely extends through the opening in the second bracket member. An internally threaded retention element engages the threads on the second shaft end section to fixedly position the annular shell and spacer sleeve between the first shoulder and the retention element. This arrangement permits accommodation of variations in the lateral positioning of the brackets with respect to the support element.
