Adjustable lift bar system

An Adjustable Lift Bar System (30) for a roll off container (90) that is made of rigid, durable, and machinable materials and is comprised of:

• (a) a pair of the vertical supports (60) for being fixedly secured to an end surface of the roll off container by a means for fastening (49);
• (b) a lift bar assembly (40) including:
• (1) a lift bar (40A) having a crown (41);
• (2) a left- and right-handed pair of lift bar flanges (43);
• (3) a pair of mounting flanges (44) with a set of apertures (44A) to receive a group of removable means for fastening (70), the mounting flanges (44) placed contiguous to each of the pair of vertical supports (60);
• (4) a long spreader tube (46) placed at a top of the lift bar assembly (40), between the mounting flanges (44), and secured to each flange (44) at each end by a means for fastening (49);
• (5) a left- and right-hand pair of short spreader tubes (47) whereby each of the pair of short spreader tubes is placed at a bottom of the lift bar assembly (40) between a respective one of the mounting flanges (44) and a respective one of the lift bar flanges (43) and secured at each end to the respective one of the mounting flanges (44) and the respective one of the lift bar flanges (43) by a means for fastening (49);
• (c) a left- and right-hand pair of bolt plates (50) each with a series of apertures (52) and each fixedly secured contiguously to the pair of the vertical supports (60) by a means for fastening (49);
• and
• (d) the removable means for fastening (70), used to removably fasten each of the pair of the mounting flanges (44) of the lift bar assembly (40) to each of the pair of the bolt plates (50), the removable means for fastening (70) being placed through the apertures (52) of the bolt plate (50) and the apertures (44A) of the mounting flanges (44) wherein the lift bar assembly (40) is adjustably and removably secured to the bolt plates (50) which are configured to have been previously fixedly secured to the roll off container (90).

A Short Adjustable Lift Bar System (33) for a roll off container (90) with an existing pair of vertical supports (60) which are rigidly secured to the roll off container, the adjustable lift bar system (33) is made of rigid, durable, and machinable materials and is comprised of:

• (a) a left- and right-hand pair of bolt plates (50) each with a series of apertures (52) fixedly welded to a first pair of gusset plates that are in turn configured to be fixedly welded to a top tube structure (95) of the roll off container (90) and an end surface (92) of the roll off container (90) and each of the two left- and right-hand pair of bolt plates further configured to be fixedly welded along a side contiguous to the end surface (92) of the roll off container (90) and further fixedly welded to an end of two sets, an upper set and a lower set, of a left- and right-hand pair of short spreader tubes (47), that end being configured to be closest to a center of the end of a roll off container;
• (b) the two sets of a left- and right-hand pair of short spreader tubes (47) whereby the upper set is configured to be placed midway between the top tube structure (95) and the lower set and whereby the lower set has a second pair of gusset plates that are in turn configured to be fixedly welded to the pair of existing vertical structures and an end surface (92) of the roll off container (90) and whereby each set is configured to be fixedly welded at the end opposite with that opposite end being farthest from the center of the end of a roll off container and that opposite end being contiguous and fixedly welded to each of the pair of existing vertical support structures and whereby the lower set is placed;
• and
• (c) a lift bar assembly (40) consisting of:
• (1) a lift bar (40A) having a crown (41);
• (2) a left- and right-handed pair of lift bar flanges (43);
• (3) the left- and right-hand pair of mounting flanges (44) with a set of apertures (44A) to receive a group of removable means for fastening (70), the mounting flanges (44) placed contiguous to the left- and right-hand pair of bolt plates (50) each with a series of apertures (52) aligned with the set of apertures (44A) wherein the lift bar assembly (40) is adjustably and removably secured to the bolt plates (50) which are configured to have been previously fixedly secured to the roll off container (90).
