How to choose wheel supports for the cart
The wheel support is a roller or wheel with a fork mount in the form of a bracket. They are available with a bolt or hole under it, with a platform. For the latter, 2-4 swivel or non-swivel mounts are used, which are inserted into special holes. The rest of the wheel supports for the trolleys rotate freely, as they are fixed with only one bolt.
This part of the truck is the most vulnerable. The wheels take on the maximum load from the weight of the transported objects. During transportation, they fight about the unevenness of the floor, hit sharp corners. In industry and production, the support often suffers from chemical influences. Therefore, periodically there is a need to buy a new one.
Why do you need it
Wheel bearing is the most important, most sensitive to negative factors and a necessary part of the truck. It gives the chance to fully realize functionality of the warehouse equipment. In axisless constructions the basis connects a wheel and a frame. Most often it is made of high-strength steel.
The wheels wear out over time. They are erased at active operation, frequent driving on an uneven floor, the earth. Sometimes they are changed prematurely because they leave ugly marks on the warehouse floor or weigh too much, they turn badly.
Important! It is best to choose the support together with the wheel. Many criteria for buying both products match. Achieve excellent performance characteristics of warehouse equipment will be obtained if you choose the right pair, and not each device individually.
Important criteria when buying
The purchase of a support should be taken very seriously, because it depends on the ease of use and functionality of the truck. The following parameters are important:
- wheel type. There are several varieties designed for riding on different surfaces;
- static and dynamic load;
- the total maximum weight withstood by the whole structure;
- resistance to moisture, chemical and other negative influences.
The first thing an experienced buyer is interested in is the maximum weight for which the structure is designed to be transported.
Important! According to the standard formula, the maximum weight must be divided into four, that is, by the number of wheels. But the result will be conditional, because when transporting the car is overloaded only on one side. Therefore, the weight of the structure is better divided into three.
The second important feature is where exactly you plan to use the cart. Not all wheels are universal and ride equally well on earth, asphalt, cement or tile. Some are worse able to cope with obstacles in the form of bumps, pits. If you choose the wrong base, it will quickly become unusable, and will soon have to change it again.
It happens that warehouse equipment is used only indoors, or is also used in the body of the vehicle, on the street. All this must be taken into account when buying. For example, rubber or polyurethane products are suitable for cemented or tiled floors. For driving on the ground, metal, asphalt coverings it is necessary to buy elastic rubberized or pneumatic wheels.
Resistance to environmental influences
First of all, it means contact with aggressive substances, such as acids. Before buying, you need to make sure that the tires, rollers, discs are resistant to the temperature and humidity of the environment where they will be stored and constantly used. In some companies, wheelbarrows are often exposed to liquids and oils that damage sensitive materials.
In warehouses where various hydrocarbons, fats are constantly used, it is better to use polyamide or polyurethane wheels. Rubber from such influences will quickly become unusable. At high humidity and where working with saline solutions, stainless steel will be the best choice. Heat-resistant products are bought for hot shops.
What are the varieties
When understanding how to choose a wheel support, it is worth considering the existing range of options from manufacturers. They are classified according to different criteria. One of the most important is the appointment. Depending on this, the wheels are:
- household. These are the simplest models installed on construction and garden carts. This category also includes furniture rollers;
- warehouse. Present on the equipment used in the transportation of goods. They are constantly subjected to intense loads, so they have improved characteristics;
- industrial. Are established on the often moved equipment;
- heavy-duty specialized, designed for use in aggressive environments.
The wheels are swivel and non-swivel. The first rotate 360 degrees along the vertical axis and maneuver perfectly in narrow corridors, cramped conditions. The wheelbarrow with non-rotating goes in the strictly set direction. This base looks like a stamped solid plate.
All wheels perform the same function, that is, they are designed to move and take on the weight of the cart. You can choose suitable options at the link https://www.fregat.com.ua/katalog/ They differ in materials, presence or absence of an arm, bearings. Consider each of these characteristics.
The purpose of the wheel and the conditions in which it can be used safely and for a long time depend on it. So, wheels happen:
- rubber. Well withstand strong blows;
- polyamide, polyurethane. They are not afraid of contact with petroleum products, aggressive substances, acids;
- soft rubber. They do not leave marks on the floor, so they are suitable for pharmaceuticals, food industry enterprises;
- pneumatic. They drive well on the street.
Pneumatic wheels are made with a corrugated tread.
Provide ease of movement. Bearings are divided into three types - sliding, roller, ball. The latter are used most often. They are the strongest, durable, cope with different loads and are almost completely unpretentious in care. Ball bearings are installed to polyurethane, cast, pneumatic wheels. Rollers are mounted on industrial wheelbarrows.
After selecting the appropriate wheels, you need to determine the load on each support. Depending on this, the appropriate mounting type is selected. Optionally, some supports are equipped with guide clamps. Some also have brakes and locks to increase functionality.
