A hand trolley is a small transport device used to move heavy loads from one place to another. It is a very common tool used by a large number of industries that transport physical products. Also called a hand truck or a dolly, the hand trolley is often used by stock persons who arrange and restock merchandise in retail stores. When used properly, trolleys can protect people from back injuries and other health problems that can result from lifting heavy loads.
Typically comprised of two small wheels located beneath a load-bearing platform, the hand trolley usually has two handles on its support frame. These handles are used to push, pull and maneuver the device. An empty hand trolley usually stands upright in an L-shape, and products are usually stacked on top of the platform. When the goods are in place, it is tilted backward so that the load is balanced between the platform and the support frame. Especially if heavy or fragile materials are moved, the person operating the trolley should return it to an upright position carefully, to ensure nothing falls off the platform.
Different types of these tools exist, and the type used is often chosen based on what type of material it will move. Hand trolleys are made of various types of hard materials, including steel, aluminum and high-impact plastic. Most hand trolleys come in standard sizes and are used for general loads, but there are some that are specifically designed for very small or large products.
Wheeled trolleys made from stainless steel are the most common type of hand trucks used. These are used in places with heavy loads to move, like retail stores and factories, and typically have wheels made out of stainless steel as well. Welded steel and metal wheel trolleys are typically much more lightweight and are often used to carry lighter materials.
Those with a frame and wheels made of a metal alloy are heavier and sturdily made. Trolleys of this type usually have a wider platform for oversized loads. Metal alloy hand trucks are typically used to transport heavy products, such as items made of steel.
A folding trolley is another type of hand tool, and is often made of rust-proof aluminum. It is also lightweight but is usually able to carry heavy loads, and can fold to take up less space when not in use. This feature also allows it to be easily transported to places where it is needed.
