Starting from a base of "zero" this is quite a statement to be able to achieve number one standing in 7 short years - hardly enough time to prove reliability of the equipment, after sales customer support - parts, service, short term rentals, provide training to technical service personnel and publish all the service literature 7 tech bulletins to keep up on product changes, operator training/maintenance pricedures. No doubt you have a 'fail safe' plan to do all that.
Many large capacity unit are reluctant to switch brands based on product literature , sales pitch. The real test comes thru customer testimonials, word of mouth, especially in certain key markets e.g. for one lumber or timber in Europe. It took Toyota decades to achieve the world number one position - think they started there entry in the US market in the late 60's along with Datsun at that time - a group nicknamed the Mayfield Mafia got Datsun going in the US). In the early days Datsun was the #1 Japanese import to the US.
Not all dealers have the capability to properly & timely service large capacity units a simple example a 100 lb- ft. torque wrench ain't going to cut it on a "big" lift and other similar tools, pick up & delivery equipment (sure one can hire a 3rd party to do PU/Delivery but the service bill/delivery charge gets higher.
Maybe you have a plan to to simply buy out the # 1 the current top dog within 7 years.
