Makita XUC01PTX2 LXT Brushless Cordless Power‑Assisted Flat Dolly Kit (5.0Ah) 18V is a convenient solution for material transport on job sites. You can use one or two Makita 18V LXT® batteries: Use one 6 amp-hour battery and get up to 60 minutes of run time under load. For longer run time, drop in a second LXT battery and double the run time (kit includes 5.0Ah batteries, 6.0Ah batteries sold separately). Makita brushless motors are engineered for up to 50% longer run time, increased power and speed, and longer tool life, and the Hand-Truck/Wheelbarrow has a Makita-built brushless motor that provides high power efficiency for transporting up to 290 lbs. of material on job sites. It has 2 speed settings, with a maximum speed of 2.5 MPH on a 12-degree incline.
