This is a big brother of Lego Technic 42035 Mining Truck. It is partially remote controlled and very fun to play with. Large-scale haul truck will make a good addition to the Lego Technic construction equipment series. General appearance, steering mechanism and suspension design were inspired by the current load capacity record holder — BelAZ 75710.
Each axle is driven by its own L motor placed inside it. Suspension consists of a ball joint, two shock absorbers and Panhard rod. The whole assembly of axle and its suspension is mounted on a turntable which enables four-wheel steering. Together with big wheels and powerful motors this provides great maneuverability. Battery box is mounted in the rear to counterweight heavy “head” in front of the wheels and allow easy and fast switching on/off and battery replacement. Since the haul truck does not have any additional functions apart from body tipping I decided not to put another receiver for simplicity (and to cut down potential set cost).
