The Operation will be by an electrically driven single power pack, including push button or key switch. Oil supply to the cylinders will be from a hydraulic mini-pack that can be remotely or locally sited. An electrical panel is included to control the mini-pack and the opening and closing of the door.

An additional remote control is supplied to operate the hatch.

This system required the installation of hydraulic piping between mini-pack and hatch door(s) together with an electrical installation.

A retractable safety grid was also installed on three open sides, manually operated
