A traction elevator is a type of elevator that uses a system of ropes and pulleys to move the elevator car up and down. Traction elevators are the most common type of elevator in use today, and they are typically used in high-rise buildings. In traction elevators, the elevator sheaves are the pulleys that hold the elevator cables and are responsible for the elevator's traction and lifting motion, as well as where it gets its name.

Freight elevators are specifically designed to move goods and materials throughout a building in contrast to passenger elevators that are predominantly focused on moving people. Additionally, freight elevators don’t require the same fit and finish as their passenger elevator counterparts, traveling at much slower speeds and possessing much heavier load capacity, these industrial lifts tend to be made for practicality rather than aesthetic appeal. Often located near loading docks or back of house in commercial buildings, freight elevators are typically not accessible by the general public.

A hydraulic elevator is a type of vertical lift that uses hydraulic fluids to move the elevator car up and down. In a hydraulic elevator, a pump forces oil into a cylinder, which pushes a piston up. The piston is connected to the elevator car, so when the piston moves up, the elevator car moves up, and when the pressure is released the elevator car lowers.

It’s a popular question: “How long does an elevator last?” The answer to this age old question relies on many factors. Based on the lift type; Hydraulic elevator, Traction elevator, Freight elevator, Passenger Elevator, Commercial Elevator or Residential Elevator as well as the usage, maintenance frequency and the elevator's physical environment are all major factors in determining the life expectancy of your elevator equipment. 

Elevator entrapment can be very stressful, as many people might panic due to claustrophobia or become anxious or irate due to the delay. In order to avoid potential injury, do not try to climb out of the elevator or force open the doors, remain calm and wait for help to arrive. Here are some guidelines for safety if you ever become stuck in an elevator.
