Hydraulic elevators are commonly used for low rise applications up to six stories.
In this system, a hydraulic cylinder and piston assembly is installed into the ground. Hydraulic oil is pumped by the pump unit through a feedline to the cylinder assembly. This causes the elevator car to rise upwards. Due to the design, hydraulic elevators are low speed (typically 100 to 150 foot per minute) and are inherently lower in cost than traction elevators.

Holeless Hydraulic Elevators - Holeless systems do not use a conventional piston/casing arrangement. They use a pair of above ground cylinders, which eliminates cost of drilling and any possibility of environmental contamination. Holeless systems ideal for building with 2-3 floors.
Duel Roped Hydraulic Elevators - Holeless system that uses a pair of above ground cylinders as well as a rope system, ideal for buildings with 4-6 floors that need a holeless application.
In-Ground Hydraulic Elevators - use both above ground cylinders and a rope system, which combines the versatility of inground hydraulic with the reliability of holeless hydraulic, they can serve up to 8-10 floors.
Traction elevators are commonly used for mid and high rise applications six stories and above. In this system, there is typically a large motor above the elevator hoistway which turns a large drive sheave. Multiple steel wire ropes are attached to the top of the elevator car frame. These hoist ropes then route vertically up the hoistway and over the drive sheave grooves. As the motor turns the drive sheave, the traction between the drive sheave and the hoist ropes causes the elevator to go up and down.
Traction elevators are more complex due to the higher speeds of travel (typically 250 to 2000 foot per minute) and the necessary addition of safety equipment to ensure safe operation. As a result, they are higher in cost than hydraulic elevators. Traction Animation | Project Gallery
Machine-Room-Less elevators are just that, elevators that don't require a machine room unlike the traditional designs of overhead traction and hydraulic elevator that do.
The new lift design presents a departure from the traditional, looped over-the-top traction rope routing of traction elevators. The ends of the cables are fixed to the supporting structure, and the lengths of the cables are connected to the car and counterweight by means of a force-multiplying, energy saving compound pulley system. Machine-Room-less elevators have become a welcome alternative to the older hydraulic elevator for low to medium rise buildings.
The MRL elevator utilizes a gearless traction type machine, which results in superior performance and ride quality compared with hydraulic elevators. MRL’s can also operate at faster speeds thus increasing the perception of quality over a conventional hydraulic and require less space to do so.

Escalators are powered by constant-speed alternating current motors. Modern escalators have single piece aluminum or steel steps that move on a system of tracks in a continuous loop.
Escalators are required to have moving handrails that keep pace with the movement of the steps. The direction of movement (up or down) can be permanently the same, or be controlled by personnel according to the time of day. Escalator Animation | Project Gallery
Inclined cart conveyors are designed for the transporting of shopping carts between an upper floor and a lower floor. The inclined conveyor includes a continuous conveyor assembly having a conveyor belt including a plurality of spaced drive lugs that engage a shopping cart. The moving conveyor belt transports the shopping cart between the upper and lower floors of shopping centers.
VRC's - Vertical Reciprocating Conveyors also called Material lifts, are designed only to move materials. VRC's are most commonly used in factories or wheelhouses where large units of material need to be moved from floors.
