We've used Vortex on our dock levelers and roll up doors in the past and have always had tremendous response time and service from them. Last night however they went above and beyond that built expectation. We had a leveler spring chain break right at closing and we had no way to secure our building. Vortex (Daniel was their technician) arrived and did a fantastic job getting getting our dock leveler down. For other Ops Mgr's our there, I was able to witness first hand how safe and diligent these guys operate. Thanks Vortex!
