The Various Classes Of Cargo Elevator

By Douglas Ellis


Some buildings are usually very busy, requiring a lot of movement of cargo up and down. To avoid injury or inconveniences, special elevators are usually installed in such building to serve that purpose only. This kind of elevator is called a cargo elevator. Goods lifts, service elevators, and freight elevators are some of the names used to refer to these models of elevators too. In the UK, the name goods lift is more common than in the United States. Americans often use the term elevator more commonly.

Generally, these elevators have a notice written on the doors or near the entrances to indicate to passengers that they are meant for goods only. As such, people are not allowed to ride in them. Although passengers are not allowed to use these elevators, it is not necessarily illegal to do so. Some elevators have also been designed with inconspicuous risers so that they can serve dual purposes. That means they can be used to ferry goods as well as passengers.

The design of these elevators allows them to support heavier loads in comparison to passenger elevators. They have capacities that range between 2300-4500 for the small versions. Larger versions have capacities in excess of ten thousand kilograms. The doors are operated manually and incorporate rugged finishes on the interior. Manual configuration of the doors is meant to avoid damage during loading and unloading.

The door configuration of these structures varies from one model to another. In small versions, the doors may be center-opening or they may be configured in a way to include two sliding telescopic doors. Larger models may have three to four sliding telescopic doors. The number of doors can be as high as six on a single goods lift.

The capacity of the equipment is one of the factors that highly determine the number of doors included. In the same way, capacity determines size. Higher capacities also imply that they have larger sizes. Size ranges from a few square feet to thousands of square feet. The type of goods to be ferried may also determine size.

Various types of freight elevators are in existence. Some of them include traction elevators and hydraulic freight elevators. Suitability of either lift to specific purposes varies. Tractions elevators offer more advantage in energy efficiency than the hydraulic variety. The design followed in constructing them permits them to handle rigors of bulky loads.

Several classes of goods lifts exist. The major ones are Class A, B, C1, C2, and C3. Each class is suitable for different capacities and sizes of loads. Class A elevators have very high capacities, but require the weight to be evenly distributed on the floor. For that reason, no single item should weigh more than a quarter of the total capacity. Handling of loads is done onboard and the handling may be manual or by use of hand trucks.

The design of Class B elevators allow them to move automobiles of various kinds to their maximum capacity. The capacity in Class C1, C2, and C3 increases in that order. These elevators allow handling of cargos using four-wheeled vehicles. For safety purposes, cargo ferried must not surpass the maximum capacity specified in the various elevator classes.
