This is the remote controlled construction equipment that can be manipulated by two children at the same time to recreate a bustling worksite. Children simply select the appropriate buttons on the master controller to switch between the gantry crane, dump truck, bulldozer and trailer truck; an additional remote allows remote operation of a different piece of equipment at the same time. Easy-to-use forward/reverse and left/right controls are augmented with buttons for activating lifelike engine sounds and blinking lights on different vehicles. The 27" tall crane rotates 360º, while its pulley raises, lowers, and slides back and forth on the boom. The bulldozer can raise and lower its scoop, and it comes with interchangeable attachments that convert it into a plow or a forklift. The cargo bed of the dump truck can be manually lifted, while the trailer truck transports the other vehicles to and from the site. Includes a second remote for any single selectable vehicle, so a friend can play simultaneously. A hand-operated elevator that feeds plastic "rocks" into a pretend grinder, plus warning signs and cones, completes the imaginary hard hat zone. Requires 12 AA batteries and 9 AAA batteries. Ages 4 and up. (6 lbs.)
