The Makita Premium Hammer Cart (T-03224) gives contractors convenient and secure transportation for a breaker hammer and bits. The large, rugged semi-pneumatic wheels role smoothly over rough terrain. At the end of the day, the Cart goes back into the truck more easily with the stair climber rails. The rails are also engineered for more convenient lifting up stairs, curbs, and other elevated surfaces. For secure transport, the adjustable strap keeps the hammer securely fastened to the cart, and bit retainers firmly hold up to four 1-1/8" demolition steel bits.
