Factors in Wheel Selection and Use

Solid Wheels.
These are made in semisteel, forged steel, or molded plastic, hard rubber, and composite materials.They should be limited to small diameters and low-speed movement and should not be used to transmit power. They have low resistance to roll, but a short life span when overloaded or subjected to rough floor conditions. They will cause load vibration because of a lack of cushioning.

Rubber-Cushioned Tired Wheels.
These consist of a metal wheel having a machined diameter onto which a rubber tire is pressed or molded. It has the lightest load-carrying capacity of those used on mobile equipment. Minimal power is required to move material, since rolling friction is minimized.

Oil-Resistant Tired Wheels. 
The tires are made of special oil-resistant rubber compounds which will resist the degrading effects of oil on rubber.

High-Traction Tired Wheels.
The tires are made of rubber impregnated with abrasive or other materials to give additional traction on ice or in wet conditions.

Low-Power Tired Wheels.
The tires are fabricated from rubber compounds that offer minimum roll resistance and have lower power requirements, causing less drain on battery operated quipment.

Nonmarking Tired Wheels. 
The tires use a rubber compound filler other than carbon to avoid floor marking and contamination.

Conductive Tired Wheels.
The tires avoid the chance of static sparking in hazardous or explosive environments by maintaining vehicle-to-floor conductivity.

Laminated Tired Wheels. 
The tires for these wheels are made up of sections of pneumatic tire carcasses threaded onto a steel band. Such tires are extremely tough, with a harsh ride. They are well suited to littered environments, such as scrap yards, and trash handling.

Polyurethane Tired Wheels. 
Though more expensive than rubber, these wheels have a significantly higher load-carrying capacity and are less susceptible to cuts than most rubber and rubber-compound wheels.Wheel hardness of polyurethane tires results in a harsher ride and increased plant floor damage.
