| This became an accepted routine situational adaptation done to allow easier access to the elevator hoistway. |
| The drop car shares a hoistway with another half-elevator, from which a tester can examine the performance of safety brake shoes. |
| The total loss of energy results from losses of motor, brake, frequency convertor and hoistway. |
| Elevator kinematics describes the motion of an elevator car in a hoistway, regardless of mass or force. |
| By means of the aerodynamic fairing, wind noise and pressure waves occurring in the hoistway are reduced to the minimum. |
| A moment later, the rope hoist main drive unit failed and the platform, with four riders still onboard, free-fell to the bottom of the hoistway. |
