The installation position of the universal wheel of a hand trailer has an important impact on the convenience and control of the hand trailer. Generally speaking, the universal wheel should be installed at the rear of the hand trailer, that is, near the handrail. This layout design makes it easy to operate whether pushing or pulling the hand trailer. If the universal wheel is installed at the front, it may make directional control difficult.
When installing the universal wheel, the key is to ensure that it is correctly and firmly fixed in the intended position. The axle needs to be perpendicular to the ground to avoid unnecessary pressure on the wheel. In addition, the quality of the kingpin caster bracket must also meet its rated load standards to ensure that excessive loads do not affect the service life of the wheel.
The function of the universal wheel should not be changed by the installation device. Depending on the different uses of the hand trailer, wheels, universal wheels and fixed wheels may be mixed, so they must be configured according to the manufacturer's design intention. To ensure the use effect and avoid unnecessary waste, the installation process must strictly follow the manufacturer's instructions.
When using a hand trailer, you also need to pay attention to care and maintenance. Trolley casters are usually used in normal indoor environments and should be avoided in harsh environments such as extreme temperatures, strong acids and alkalis, high salt, chemical solvents, grease or seawater to maintain their performance. In addition, depending on the specific use, other measures may need to be taken, such as choosing appropriate hardware materials, casters and lubricants. It is important to note that some materials may contaminate the ground, so special attention should be paid when selecting and using them.
