What is a machine Roomless elevator?

A machine room-less (MRL) elevator does not have a separate room for housing the elevator’s motor. The specially-designed motor is installed directly in the hoistway, either at the top or bottom of the shaft. In many ways, an MRL elevator looks like a “normal” elevator. The lift may be a traction or hydraulic machine.

What is Roomless lift?

Machine room less elevators (usually shortened to as M.R.L. or MRL) are a type of either traction or hydraulic elevator which do not require a machine room for the elevator.

How do you calculate elevator capacity?

SHORT TONS: Multiply cubic feet capacity times weight of product per cubic foot and divide by 2,000. METRIC TONS: Multiply cubic feet capacity times weight of product per cubic foot and divide by 2,204.62. For engineering purposes, Maxi-Lift recommends using water level capacity as the basis for calculation.
