A roller dolly is a tool used to transport large or heavy objects. It is used by placing multiple objects under the object to be transported. Movement and installation of machine tools and air conditioning equipment, layout changes in factories, etc. can be performed smoothly. The direction can be easily changed by the rollers, and turning can be done more smoothly by using the dedicated handle. Products that use urethane resin rollers minimize floor damage. Since the self-propelled product moves forward and backward by operating the ratchet handle, it is suitable when fine adjustments are required in a narrow space. There are products in which two roller wheels are connected by two rods, products in which a nail is inserted into the lower part of an object and lifted up to carry it, etc.
