When sourcing vehicle movers, the most critical factor is the Load Capacity, which typically ranges from 1,500 lbs to over 10,000 lbs per unit. You must ensure the Hydraulic System or Electric Motor is rated for the specific vehicle types you handle. For manual hydraulic jacks, look for heavy-duty steel construction and reinforced nylon or polyurethane casters to prevent floor damage. If sourcing electric models, prioritize Lithium-ion battery endurance and remote control range (up to 50 meters) for operator safety.
