The parts, such as drawwoks, substructure, supporting seat, mast, power skid etc. are trailer-mounted modules, and can be assembled and installed on site.
The mast raised by hydraulic cylinder can be divided into three sections. Mast foundation section is connected by pin, the upper and middle section are extended and retracted mechanically.
Parallelogram substructure can be folded into pieces;

 therefore floor space is quite small.
