On the platform is a swivelling crane (14) and seatings for a load to be carried. One axle is below the trailer centre of gravity (loaded). The crane is worked by a manually operated hydraulic pump. It is mounted on vertical axis rollers, allowing it to be rotated manually with its load. The trailer brake is of the inertia (4) type. For moving the cable drums there are supports to allow it to turn and cable guides (21).</p> |
