Abstract: The present invention relates to a waste material collection tub which is provided with a pair of selectively removable tub dumping pins which are precisely located in relation to the tub lifting pins for use with appropriate material transport vehicles to ensure a longer life for such tubs and to maintain them in good working condition throughout such period. The prior art tubs only provide rigid non-removable dumping pins which are exposed to the severe environment, or subject to damage by being struck by other vehicles in the high traffic areas adjacent to commercial sites and cannot be nested together with other similar tubs during transport from site to site.
