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.

Capacity is among the major factors that play a major role in determining how many doors are included into the equipment. Similarly, size varies with capacity. Appliances that have more capacity are also huge in size to compensate for the high capacity. Capacity can be as high as several thousands of square footage. Size is also reliant on the kind of good ferried.

Freight elevators are of various types. Hydraulic and traction freight elevators are some of the common examples. They are both efficient and suitable for various applications. However, in terms of energy efficiency, traction models are usually preferred more than the hydraulic varieties. Traction elevators incorporate designs that allow for handling of rigors of heavy weights.

Goods lifts exist in various classes. The classes include Class B, C1, C2, C3, and A. Every class is specific in the load capacity and size it can handle. Capacity in Class A is relatively high, but weights must be evenly distributed on the floor. That makes it necessary to keep the weight of any single item below 25 percent of the total capacity. Cargos can be handled onboard using hand trucks or manual means.

Class B freight elevators are meant primarily for moving automobile trucks and other forms of vehicles to the specified capacity. Class C1 have higher capacities and allow cargo handling by means of four-wheeled vehicles. In all models, capacity must never be exceeded for safety reasons.
