Freight Elevators

Freight elevators are specifically designed to carry tools, equipment or products and can be offered in different styles based on the application and the needs of the owner and architect. The size and shape of the unit can also vary to meet these needs. Every manufacturer has “standard” size elevators, but customication of these standards are available.

HYDRAULIC FREIGHT ELEVATOR:

Typically these are the most standard type of freight elevators found throughout the country. They are a power elevator where the energy is applied by means of a liquid (oil based or vegetable based) under pressure into a cylinder equipped with a plunger, the movement of which imparts movement to the elevator car. They are engineered for low to medium rise buildings having less than 60’ of travel, where quality performance and reliable operation is essential. They all have oil hydraulic cylinders placed either in the ground encased in PVC pipe or cylinders that stand in the hoistway for shorter travel distances. Manual or power operated vertical horizontal sliding door operation is another common trait. Loading capacities are generally higher than passenger style elevators and these capacities are close to limitless.

TRACTION FREIGHT ELEVATORS (cable elevator)

Geared traction elevators that are designed for freight are available with power or manual operated vertical or horizontal sliding, doors. They are generally designed for medium to high rise buildings having over 50’ of travel where quality performance higher speeds are required. A geared traction machine is a design in which the power from motor is transmitted to the drive sheave through a reduction gear.

FREIGHT ELEVATOR LOADING APPLICATIONS

CLASS A: General Freight Loading: When the load is distributed, the weight of any single piece is not more than ¼ the capacity of the elevator and the load is handled on and off the car platform manually or by means of hand trucks.

Class B: Motor Vehicle Loading: The freight elevator is used solely to carry automobile trucks or passenger automobiles up to the rated capacity of the elevator.

Class C: Industrial Truck Loading: A four-wheeled vehicle may be used to load and unload the elevator. The combined weight of the vehicle and the load cannot exceed the rated capacity and may be rolled onto the platform as a single unit.

Class C: Industrial Truck Loading: During loading and unloading, max load on the platform may be up to 150% of the rated capacity. This enables you to use a forklift to load a car with freight weighing up to the rated capacity.
