Freight elevators are specially designed to transport materials and products through a commercial building. Unlike passenger elevators, freight elevators travel at faster speeds, are equipped with heavier loads and are better engineered to withstand tougher operating conditions. With so many different types of these devices on the market today, it can be difficult to know where to start when searching for the perfect one for your business. Here are some of the main features to look for when making a selection.
The most important aspect to consider is the capacity of the device. If you need a freight elevator for a big warehouse, then it probably won't be too heavy duty or complex. However, smaller warehouses often have restrictions on the maximum load that can be transported using a single system. For this reason, you should also check out whether there are any wooden gates or other obstacles that could cause problems when transporting products in the elevators. Some elevators have safety features such as automatic locking mechanisms, whereas others will require manual entry.
One of the first classifications of freight elevators is a two-stage electric motor vehicle loading freight elevator, also known as a class b lift. These elevators have an elevator window that can be opened to full capacity, while only being closed upon arrival. This allows two types of goods to be loaded, thereby reducing traffic within the warehouse floor.
A two-stage system uses a single-axle platform and two doors, one on each side. These can either be operated mechanically, hydraulically, electrically or pneumatically, depending on the model and intended purpose. The doors are usually placed on either side of the loading dock, allowing goods to be loaded from both sides. A good example of a class b loading elevator is the 'high-bay' type, which have two doors, but is high enough not to block walkways. Most of these types of freight elevators are used in loading/unloading zones.
Class I freight elevators are generally considered the safest because they use either air-powered or manual methods of lifting. In addition, they employ safety-related features such as automatic locking mechanisms, non-combustible materials and steel wall panels. They have high ceilings up to 15 feet, which is sufficient for some industries, such as in the banking or insurance industry. However, classic doors require manual entry or the use of codes, so they cannot always be used for sensitive jobs. These types of freight elevators also use a number of safety-related features, such as non-combustible steel floor panels and emergency brakes.
Class D and E-types are the last two types of electric, non-rail freight elevators. General freight loading elevators are intended to lift normal-sized containers, while special order specialty elevators (such as pallet loading) can be built to lift very heavy items. These special order elevators are most commonly used in industrial applications. Class D and E-types can go to a maximum capacity of 1500 feet, but their maximum height is lower than the previous two classes. They also offer better weight bearing capacity and higher speed.
