Title
(EN) Apparatus and method for variable torque braking of escalators and moving walkways
(ZH) 用于自动扶梯和移动人行道的可变力矩制动的装置和方法
Abstract
(EN)
A braking apparatus and a method for an escalator or moving walkway includes a braking element, a linearly controllable solenoid assembly, a biasing mechanism, and a control device. The braking element adapted to engage a brake drum or brake disk on a drive shaft of the escalator/moving walkway. The linearly controllable solenoid assembly includes a brake coil and an elongated member. The elongated member is moveable linearly along an axis and the braking element is coupled to the elongated member. The biasing mechanism arranged to bias the elongated member in a first direction along the axis to increase a torque applied to the drive shaft by the braking element.
