we have a JLG ssv10, the perfect size for your needs. Unfortunately JLG has a lemon here. $17,000 new.....in 2 yrs we've replaced both drive motors, the joystick control, and now the main control panel. we have spent about $5,000 in replacement parts and labor on this picker and JLG has refused communication with our dealer to resolve any of these problems and concerns. I would caution you to look at something manufactured from some one other than JLG.
JLG Mobile Vertical Lifts (MVL Series) 15MVL 184.4 platform hieght. 500 max capacity operator and load. Does not require fall protection.
20MVL 235.20 platform 350 max capacity operator and load. Does not require fall protection
The closest match I can see is the Wave truck from Crown. The work height will reach up to 195" (just over 16') and it weighs 1225 lbs. This also has a fall protection solution without a harness, but it will not allow you to pick 500 lbs at a time. The load tray capacity is 200 lbs and the load deck is 250 lbs.
