In addition to lifting, supporting, transporting and placing caster products of SHANGXIN, push and pull are also commonly used actions when manual transportation of goods is required. Heavy physical labor is common in production and logistics environments and puts employees at risk. Depending on the weight of the goods being transported, pushing and pulling can take a lot of effort and can overload muscles, tendons and joints over time. This can affect the spine, knees, hips and the entire arm and shoulder area.
To reduce the risk of injuries and problems, many countries have introduced guidelines to limit large loads that can be transported manually. When working for long periods of time, caster manufacturers recommend that we use no more than 15% of our own muscle strength. The problem is that muscle strength varies from person to person. It is also very difficult to accurately assess how much force is actually needed to push or pull a load. Therefore, it is almost impossible to make instructive restrictions on the use of force by employers and employees.
In a sense, pushing and pulling loads can make work easier. When things are too heavy to hold or carry, vehicles and transport equipment with single wheels or casters are often used to reduce work pressure. But moving these things can also be exhausting. This is because you encounter resistance when starting, rolling, changing direction or passing obstacles. The nature of the resistance depends on factors such as the surface you are moving on, the weight of the load and the type of industrial castor with bearings and wheel arrangement. The quality of the wheel you use is also crucial.
Starting and rolling resistance occurs whenever you push or pull an object. It always takes force to move a stationary wheel, and it also takes force to keep the vehicle moving. When moving an object over the ground, the tread is constantly pressurized and decompressed, and some of this energy is lost in the internal friction of the tread material. This causes rolling resistance. Increasing the wheel diameter is one way to reduce rolling resistance, but choosing the tread is also important. The geometry, rigidity and elasticity you choose have a significant influence on the operation. Using swivel castors increases the rotational resistance when operating with push and pull movements. This resistance occurs because force is required to move the castor into the desired position when changing direction.
These products combine excellent running properties with high elasticity. Very low starting and rolling resistance, making them the ideal solution for almost all applications. Specially designed for demanding applications in intralogistics, with a high-quality tread with optimized geometry. Made from a reaction-cast polyurethane elastomer. Very resilient and characterized by a slightly crowned structure. This reduces the contact area during rolling and optimizes the pressurization and decompression action during rolling. The end result is a 40% reduction in rolling resistance compared to other polyurethane tires. This means that vehicles and transport equipment equipped with the wheel series are easier to push and pull. The tread has an excellent dynamic load capacity despite its 92° hardness. This allows the wheels to be handled at higher speeds.
The in-house test laboratory has a special test station for calculating the starting, rolling and rotational resistance. The laboratory also carries out tests for crossing obstacles. These tests are more stringent than the standard requirements. This ensures that the wheels and castors meet real-world requirements.
