Same design as the Standard 03S Series but shorter and bigger so it can bear load capacity up to 300 kg. Enhanced PA wheel is strong and durable, it can rolls easy thanks to the double ball bearings. Suitable for lifting heavy machine.
Extra heavy duty type: painted coating & tapered bearing. The steel bracket bears high load and promising smooth operation. However combining with rubber wheel, this strong bracket is just showing 50 - 75% of its ability.
