Our Skyjack DC Electric Scissor Lifts are a great option for aerial work on flat surfaces. The 4740 has a working height of 38', an inside platform width of 42", and an inside platform length of 84" with a 4' extension deck. The base width of the machine is 47", meaning this machine does not fit through a common single-man doorway. The rails can be collapsed to a stowed height of 79" so they can fit through the common size double-doorway. This machine has a weight capacity of 700lbs. Overall they weight 5496lbs with the dispersed down-pressure on each wheel being approximately 2600lbs unloaded. All of our tires are non-marking.
