Practical counterweight stacker is ideal for use anywhere standard straddle legs might interfere with operation. Illuminated voltmeter indicates battery status. Remote control has a magnetic backing that allows it to be stored anywhere on the machine. Maintenance-free 12V battery with 10 amp, 12V charger. Stacker may be used on AC current while charging. Also includes floor lock and safety screen. Choose either standard power lift models or ones with a variable-speed steerable power drive system that allows a single user to easily move heavy loads and control forward and reverse movement of the stacker. With the power drive model, finger-tip controls are built into the steering handle for precise movement in confined spaces; a red emergency switch automatically reverses direction when coming in contact with an obstacle, and it is powered by two batteries. NOTE: be sure to order enough counterweight for your planned load. Counterweights are sold separately.
