Differences of Exterior Freight Elevator

What is an Exterior Freight Elevator?

Types of exterior freight elevators

Based on load capacity, they can be divided into small exterior freight elevators (2-5 tons), medium exterior freight elevators (5-15 tons), and large exterior freight elevators (15-50 tons). According to the door opening method, they can be classified as full-door elevators and half-door elevators.

Structure of exterior freight elevators

Exterior freight elevators include components such as machine rooms, shafts, guide rails, carriages, electrical systems, mechanical devices, and door systems. The machine room houses the main operating machinery of the elevator; the shaft serves as the elevator's travel path; guide rails guide the elevator's movement; the carriage is used for carrying goods; the electrical system provides power and control; mechanical devices drive the carriage; and the door system opens and closes the doors.

Main technical parameters of exterior freight elevators

These include rated load capacity, operating speed, number of floors, door opening method, door dimensions, interior dimensions, and power supply type. The selection of these parameters directly affects the performance and cost of the elevator.

Exterior freight elevator operating systems

The main systems include traction elevator systems, magnetic levitation elevator systems, and hydraulic elevator systems, with traction elevator systems being the most commonly used. These include gear traction, belt traction, and aerial cable traction systems.

Main safety devices of exterior freight elevators

These include overspeed protection devices, endpoint stopping devices, door interlock devices, emergency stop buttons, and overload protection devices to ensure the safe operation of the elevator.

Applications of exterior freight elevators

They are mainly used in industrial manufacturing, warehousing, logistics, commerce, and agriculture sectors. They are suitable for transporting heavy or large materials, components, or finished products on production lines, etc.

Differences Between Exterior Freight Elevators and Regular Passenger Elevators

Different purposes

Exterior freight elevators are mainly used in industrial and warehousing facilities for transporting goods and materials; regular passenger elevators are primarily used for vertical transportation of people in buildings.

Different cabin volume and load capacity

The cabin space of exterior freight elevators is large and does not need to consider the entry and exit of personnel, thereby maximizing the space for carrying goods. The load capacity is also much greater than that of regular elevators, generally ranging from 2 to 50 tons. The cabin space and load capacity of passenger elevators are much smaller by comparison.

Different door opening methods

Exterior freight elevators generally use a full-door opening method to facilitate the entry and exit of goods, with a wider door opening. For safety reasons, passenger elevators typically only open half the door.

Different interior decoration

The interiors of exterior freight elevator cabins are undecorated and use protective and traction devices specifically for goods. In contrast, passenger elevator cabins are equipped with lighting, decorative elements, and operational panels and railings for passenger use.

Different operation controls

Exterior freight elevators automatically adjust operational parameters based on the height and center of gravity of the load to ensure safe operation, while the operation of passenger elevators is restricted by considerations of passenger comfort, leading to smoother acceleration and speed.

Significant price differences

For identical specifications, the price of an exterior freight elevator is generally 2 to 5 times that of a passenger elevator, due to its significantly higher load capacity and material requirements.
