The surfaces on which trolleys and machinery are to travel are one of the main discriminatory factors when selecting wheels and their characteristics.
Floors can be extremely diverse: from tough and compact surfaces to surfaces that are fragile, subject to the risk of damage due to the transit of machinery or trolleys.
There may also be requirements linked to the presence or absence of obstacles on the floor surface, calling for adequate wheel and bracket types and the need to comply with restrictive hygiene requirements or to provide resistance to the more or less aggressive chemical substances found in industrial environments.
Non-marking wheels for industrial floors requiring protection
Applications in sectors such as the food or pharmaceutical industries may involve special conditions in terms of cleanliness and hygiene, plus the need to protect the floor surfaces.
The market offers non-marking and non-staining wheels designed to handle different loads in different operating conditions, while simultaneously protecting the floor surface on which the trolleys are used.
Classification of non-marking wheels by load capacity
In relation to performance, it is useful to classify non-marking/non-staining industrial wheels based on the load they are to carry, using as a reference the types of materials used by leading wheels manufacturer Tellure Rôta:
- For light loads: grey standard non-marking rubber and thermoplastic wheels
Suitable for trolleys with light loads. Compatible also with fragile flooring, in the presence of obstacles, and in domestic/institutional environments.
Application examples: luggage trolleys, tool trolleys, institutional and catering trolleys, trolleys for indoor industrial use, tubular trolleys.
- For medium loads: non-marking blue thermoplastic polyurethane and elastic rubber wheels
Thermoplastic polyurethane wheels are excellent for trolleys and machinery with medium loads, also in the case of continuous handling. The very low rolling resistance of these wheels guarantees the minimum load handling effort; these wheels are suitable for indoor use also on fragile surfaces such as tiles or cement-resin flooring. The key features include: do not mark or damage of fragile flooring.
Suitable for frequent washing and sterilization.
Application examples: tubular trolleys, mobile scaffolding, trolleys for indoor industrial use in the chemical and food sectors.
Medium loads can also be handled using wheels with an non-marking blue thermoplastic polyurethane covering and polyamide 6 centre. These wheels offer exceptional performance on uneven flooring and in the presence of obstacles.
- For heavy loads and mechanical handling: TR-Roll polyurethane wheels
The TR-Roll Elastic Polyurethane version developed by Tellure Rôta combines the elasticity and vibration damping properties typically associated with elastic rubber with the specific characteristics of polyurethane. Overall, TR-Roll Polyurethane wheels offer excellent characteristics in terms of their ability to carry heavy loads, wear resistance, low noise and floor surface protection. A version is also available with an ergonomic round profile, which makes it possible to reduce starting effort.
If combined with suitable brackets, these wheels guarantee excellent performance for mechanical load handling at up to 16 km/h.
- For high temperatures: non-staining silicone rubber wheels
In addition to load requirements, it may sometimes be necessary to consider also the operating temperature of trolleys and machinery.
Non-staining silicone rubber wheels with aluminium centre, both materials featuring excellent heat resistance, are the ideal solution load handling at high temperatures (e.g.: oven trolleys), while simultaneously protecting the floor surface.
All handling activities take place on different types of flooring that may be more or less fragile; the use of suitable wheels is essential to protect the flooring and allow faster load handling.
