The company developed floor control, automatic elevators, acceleration control of car safeties, and a number of freight elevators. The Sprague-Pratt elevator ran faster and with larger loads than hydraulic or steam elevators, and 584 elevators had been installed worldwide.
Many vehicle systems on a conventional vehicle are negatively affected by the change in attitude coming from changes in load - specifically a heavy load in the rear seat or luggage compartment. [1] This change in attitude affects aerodynamic properties, headlight aim , braking , bumpers, shock absorption from the suspension and the vehicle's ...
Many elevator installations now feature emergency power systems such as uninterruptible power supply (UPS) which allow elevator use in blackout situations and prevent people from becoming trapped in elevators. To be compliant with BS 9999 safety standards, a passenger lift being used in an emergency situation must have a secondary source of power.
A leveling kit usually consists of stronger front springs to lift the front end ride height so that it matches the rear ride height. This gives a more balanced/level look to the vehicle when unloaded/empty and increases offroad capability/angles at the cost of less traction, handling, aerodynamics and head lifting when loaded with cargo in the ...
The system also allows for the turnstiles to work together with the elevators so when you swipe your access card on the turnstile, it calls the nearest elevator. There is also an app for the elevator system that allows you to call and type in your destination from your mobile device reducing wait time.
Modern automatic level in use on a construction site. A level is an optical instrument used to establish or verify points in the same horizontal plane in a process known as levelling. It is used in conjunction with a levelling staff to establish the relative height or levels (the vertical separation) of objects or marks.
Originally developed at General Motors as an automated guideway transit system, GM was forced to divest the design as part of an anti-trust ruling. The design eventually ended up at Otis Elevator who replaced its linear motor with a cable pull and sold the resulting design for people mover installations all over the world.
MULTI is the first cable-less elevator developed by TK Elevator (formerly ThyssenKrupp Elevator). Rather than using cables to lift the elevator, MULTI uses linear motors. [1] As well as moving vertically between floors of a building, MULTI can also move horizontally through a floor of a building. MULTI is being tested at Rottweil Test Tower. [2 ...
