This model has been designed to meet specific requests:
A front brake to be able to operate the pedal while pushing the cart.
A polyurethane anti-crushing wheel, allowing it to support prolonged static loads for several months.
A cast iron rim, resistant to a very high load of 1 ton per unit.
A plasticized tempered nylon internal spacer anti-abrasion, to withstand wear from the internal bolt.
A double ball bearing to limit pushing efforts.
A double brake lock, allowing simultaneous locking of the rotation of the plate and the wheel.
In summary, this is a model designed for very intensive use.
