Respectful correction to comments above...
OHIO and MONTANA are not nicknames of the products. They were the R&D design project names for the EcoSpace developement. They have absolutely nothing to do with states in which pilots were conducted. They are acronyms. I am not at liberty to disclose what the acronyms stad for however.
The MonoSpace is a traditionaly designed, heavier duty MRL that utilizes both an MX10 and an MX20 machine depending on the duty of the unit. The EcoSpace is a light-duty MRL which is designed around an integrated cab/sling to greatly reduce weigh and cost. The EcoSpace only uses the MX10 class of machines and the roping configuration changes from 2:1 to 4:1 when duty requires. The speed of the EcoSpace is also limited to 150fpm.
