Could've been 5 stars if the braking mechanism was designed to latched solidly. One has to manually fidget with placement of the lever/handle just in the right way so the brake plate presses against the wheel. But this isn't as solid as expected or should be. Also, the brake plate seems to bend somewhat over time, so that it doesn't press against the wheel as much in later uses. Bottom line - it works good, but I'm hesitant to leave in the brake position for too long as it "might wear out" (on major construction jobs, this isn’t an option), and time will tell if the brake works good over years of use. When all 4 wheel brakes are engaged, it's of course solid.As for load capacity, the wheels easily handle loads I expect to encounter (1000-1200lbs overall, 300lbs per wheel). So for me, this works great for small construction jobs. Great value for the money.Scaffold used on: Brand "Scaffolding Today". Part# 110756. Heavy-duty 5' x 6'-6" T Walk-thru Frame W-Style.
