ProAim Doorway Dolly Roundy Round w/ bazzoka, offset turret, seat, riser, track wheels The Quad Dolly has an extremely solid Chassis Design, and the upper base is made of Solid Wood with high-quality finish. This makes it extremely robust and can easily handle payloads of up to 500 kg/1100 lb. Quad Dolly can be equipped with Skateboard Wheels or Standard Track Wheels for use on tracks or Pneumatic Wheels for standard floor use. You can use a tripod, a bazooka, a slider, or any other standard Euro Mount Accessory and configure it your needs. The Quad Dolly comes with removable sideboards that add an extra 10" per side for increased platform width to enable the Cameraman and the assistant to stand, sit or even kneel on the Solid Platform. We designed the Quad Doorway Dolly while keeping mobility and easy operation in mind. With an All-wheel steering system, the Proaim Quad Dolly maneuvers on small sets like no other platform dolly. It's capable of negotiating an extremely tight circle of 2 m (6 ft). Steering Push bar allows pushing/pulling the Dolly on the ground with standard or on the track extremely smooth and easy.
