Abstract

A mounting structure for supporting one or more pantographs in a machine is disclosed. The mounting structure includes a bottom support structure and a middle support structure removably mounted on the bottom support structure. The middle support structure includes a pair of secondary front legs removably coupled to the pair of primary front legs. The middle support structure includes reinforcement members for removably connecting the top portion of one of a secondary front leg and a rear leg with a deck. The mounting structure includes a top platform removably mounted on the middle support structure for supporting the pantographs. The top platform includes a first supporting member and a second supporting member. Each of the first supporting member and the second supporting member is supported along a first side arm and a second side arm of the deck, respectively.

First claim

What is claimed is:

1. A mounting structure for supporting one or more pantographs in a machine, the mounting structure comprising:
a bottom support structure including:
a pair of primary front legs;
a first horizontal arm connected to a top portion of the pair of primary front legs; and
a pair of supporting legs connected between the first horizontal arm and a bottom portion of the pair of primary front leas, wherein the pair of primary front leas, the first horizontal arm, and the pair of supporting legs are coupled to each other by a welding connection;

a middle support structure, removably mounted on the bottom support structure, including:
a pair of secondary front legs detachably coupled to the pair of primary front legs of the bottom support structure by a fastening member;
a pair of rear legs coupled to the pair of secondary front legs by a deck, the deck is disposed on a top portion of the pair of secondary front legs and the pair of rear legs, wherein the deck includes a front horizontal arm, a rear horizontal arm, a first side arm, and a second side arm;
at least one support bar connected between one of the pair of secondary front legs and one of the pair of rear legs; and
at least one reinforcement member, disposed along a length of the deck, for connecting the top portion of one of a secondary front leg and a rear leg with the deck,
wherein the pair of secondary front legs, the pair of rear legs, the at least one support bar, and the deck are detachably coupled to each other by a fastening connection; and

a top platform, removably mounted on the middle support structure, for supporting the one or more pantographs, the top platform including a first supporting member and a second supporting member spaced apart from the first supporting member, wherein each of the first supporting member and the second supporting member is supported on the first side arm and the second side arm of the deck of the middle support structure, respectively.
