The main task and the main reason for which were set up carts – it is the movement of goods in different weights for short distances. This may be to move within the plant, factory, yard area and so on. And the main load for this rests on an essential element of a cart – the wheel. The wheel can be considered as an element of taking over the entire load. So it is when you consider that the load pushes onto the platform truck, and she in turn at the wheel. This means that the selection of wheels should be made taking into account the weight of the load and weight of the truck. If we look closely at the table of technical parameters of platform trucks, we see that the load platform Truck is in the range from 200 to 900 pounds. Itself truck can weigh in the range of 14.7 to 65.6 kg, and from this it is easy to understand that the stated load capacity ultimately rests on the wheels themselves.
On the platform truck pose two types of wheels. First – wheel and tire from cast rubber, the second – the wheels with pneumatic tires. For each wheel or wheel bearings have enough accessories to complement functionally the wheel. The most common – A brake system and wheels with tires from a gray non marking rubber floor. The latter are used when necessary to keep the floor clean after passing on him a loaded truck.
Wheel of black rubber with turn or turn truck on the site can leave trudnostiraemye footprints on the floor. Tire wheel of a gray rubber exclude such an accident. Of course the fact that the tire has a different color does not mean that it is made of another less strong or less-quality rubber, which means it does not affect the specifications and load wheels. Wheel bearings (or rollers) are located on the platform carts on the corners platform, to be exact as close as possible to its corners. Brackets castors attached to the bars below. Such an arrangement provides a stable support stability, and thus maximizes all of the cargo area of the platform. It is also a positive impact on the maneuverability and controllability .V standard truck includes two swivel and two fixed castors same height, while turning set by the handles, and it makes it much easier to manage truck. The greatest agility equipment provides four swivel wheels. In this case, the ground force is applied to rotate the push cart on the rear-wheel drive, located on the handle and the front wheels are the thrusters. Truck with a complete set requires some management skills, especially if heavy goods are transported at a sufficient speed to a rotation of inertia truck had become unmanageable. The most common example of such a truck – a food cart in a supermarket. Try to take her empty at low speed – it's easy and quite convenient. But if it is filled with food, even if the average speed after a sharp turn in time to align the cart is difficult. The reason for this is just a weight and all the castors swivel. Features castors or rollers, mounted on truck platform may be very different. They depend on various areas and purposes of the application and may be selected individually. In the future we will return to this subject and consider the region industries where applicable wheels and bearings are installed on platform trucks.
