The R18RT "Mega Plus" boasts the highest carrying capacity and load-handling capability in the RocknRoller® Multi-Cart® lineup. It instantly transforms into any of 8 configurations, making it effortless to move exceptionally large amounts of equipment. Featuring super wide R-Trac 8”x3” front casters with brakes and 10”x3” rear wheels, it easily rolls heavy loads over grass, dirt, gravel, and soft carpet. The custom-designed R-Trac Ground-Glider Wide wheels offer low-profile no-flat tires, lightweight yet strong polymer hubs, and low rolling resistance. These wheels provide pneumatic-like cushioning and wider load dispersion over soft terrain, resembling racing wheels. The 8”x3” brake casters are 50% wider than standard casters, while the R-Trac 10”x3” rear wheels are 33% wider. This design allows the cart to glide over soft terrain while maintaining a low profile for better loading ergonomics and compact storage. The frame bed and foldable handles feature 25% larger tubing for increased strength, capable of handling even bigger loads. With thicker steel tubing, the R18RT spaciously extends from 42” to 60" in length and boasts a weight capacity of 700 lbs, yet its fold-away design allows for compact storage to fit in any vehicle. Crafted from extremely tough textured powder-coated steel, it ensures durability through thousands of trips. The non-skid frame bed surface prevents load slippage. With the R18RT "Mega Plus," you can easily transport your gear across rough terrain, whether it's at a job site, backyard wedding, over gravel or grass, at an outdoor festival, sporting event, or any condition imaginable.
