Gervall UCM100

The UCM100 module is designed to control the supply of the coil of the electromagnet installed in the Gervall overspeed governor.

The module detects when the cabin is stopped at floor level and with the doors open through the serial and floor level inputs. The coil is stopped to activate the protection, which results in the cabin being protected against uncontrolled movement. The system does not lock the governor when the doors are closed, which allows normal operation of the elevator.

These overspeed governors are valid for activating instantaneous safety gears with rollers, instantaneous with shock absorber effect and progressives. There is the possibility of installation as overspeed governor (traditional overspeed governor) and/or for fulfillment of +A3 amendment of regulation N81:1/2:1998+A3:2009. As an overspeed governor for the installation of remote tripping at 24VDC (1A), 48 VDC(0,5A) and 230 VAC (0,15A).

For the traditional overspeed governor installed for +A3 the tripping mechanism will be 24 VDC (1,9A.), removing supply from the coil.

This overspeed governor can be installed on the left and the right of the guide rail without needing to be rotated and without any change in the design. Either direction of the pulley rotation can be used as direction of the activation in descent.

These overspeed governors aactivate on opening their levers, by the effect of centrifugal force, when there is an overspeed of the car in both ascent and descent.

The roller rotates in the same direction as the lift moves until it touches the blocking disc and is braked between this disc and the wedge of the pulley, producing the mechanical tripping of the overspeed governor. This system allows infinate tripping points because they happen on any position of the roller surrounding the disc.

These overspeed governors are valid for activating instantaneous safety gears with rollers, instantaneous with shock absorption effect and progressives.

Gervall Europa

These overspeed governors are set in motion when the levers open by centrifugal force, both in ascent and descent, when the cabin overspeeds. The locking device for overspeeding is created by the centrifugal forcé which opens the levers pushing them towards a roller in the centre of the pulley where a solid, fixed locking device connects with the axis of the pulley via a wedge.

The roller revolves in the same direction as the lift until it touches the disc of the locking device and is stopped between the disc and the wedge of th pulley, thus producing the mechanical locking of the oberspeed governor. This system allows infinite locking points as they can be produced in any part of the roller around the disc. These overspeed governor are valid for setting off instantaneous grip gears with rollers, which are instantaneous with a cushioning and progressive effect.
