A High Clearance Sprayer Jack is designed to allow for tire changing and under-carriage maintenance/repair tasks on sprayers and other types of big equipment, such as tractors, trucks, trailers, etc. Workers with disabilities do not need to carry stacks of blocking to jack up tall farm equipment with this tool. In general, lift jack/jack stand models are designed to be sturdy and heavyweight, have lifting capacities of at least 12 tons, and are incrementally height-adjustable from 40 to 80 inches. They are powered by compressed air, hydraulic oil, or air-over-hydraulic and operated by pumping a handle or by pressing an attached or remote-control button.
