Both the front and rear frames have parallel upper horizontal tubes 1 and lower horizontal tubes 2, which are horizontally arranged and made of 100mm diameter round tubes. Multiple vertical support members 3 are sequentially arranged along the length of the horizontal tubes between the upper and lower horizontal tubes 1 and 2. Each vertical support member 3 includes a vertically arranged L-shaped support plate and a vertically arranged square tube support member. The vertical support members 3 at both ends of the upper and lower horizontal tubes 1 and 2 use L-shaped support plates, while the other vertical support members 3 use square tube support members, which are made of 60mm × 60mm square tubes. A first diagonal brace 4 is provided between adjacent vertical support members 3. The first diagonal brace 4 is X-shaped and is also made of 60mm × 60mm square tube.

[0025] like Figure 1 As shown, multiple vertical support members 5 are sequentially arranged along the length of the horizontal tubes 1 and 2 of the front and rear frames, respectively. Each vertical support member 5 is perpendicular to its corresponding horizontal tube and is made of 30mm x 30mm square tubing. A second diagonal brace 6, X-shaped and also made of 30mm x 30mm square tubing, is also provided between adjacent vertical support members 5. Reinforcing support members 7, also made of 30mm x 30mm square tubing, are provided between corresponding vertical support members 3 of the front and rear frames.
