The A-frame is an A-shaped structure, pivoted on a fixed base and driven by 2 hydraulic cylinders. The fixed base is a mounting skid with container-type interface mountings. The A-frame is secured to the base via a bolted connection.
The A-frame structure incorporates a movable crossbeam, to which the supplied snatch block is attached via a pad eye. The movable crossbeam has two fixed positions: “operational” and “stowed”. In the “stowed” position, snatch block installation, maintenance, and securing are performed, as well as towed vehicle connection and securing to the umbilical cable. In the “operational” position, towed vehicle launch and recovery operations are carried out via the snatch block. Locking of the crossbeam in the operational position is ensured by hydraulic locks (pilot-operated check valves on the hydraulic cylinders). The hydraulic cylinders driving the frame enable outboarding and inboarding of the frame with the towed vehicle.
An HPU mounted on a common hydraulic oil reservoir is provided for the frame hydraulic drive. The A-frame HPU design incorporates an emergency hand pump connected via high-pressure valves to ensure frame recovery to the “stowed” position.
The HPU scope of supply includes a standard pressure gauge on the main line, a hydraulic fluid filter, and a fluid level indicator (max, min) on the reservoir.
To prevent hydraulic fluid leakage during system filling and draining, all fluid reservoirs are equipped with shut-off valves (or quick-disconnect couplings) to enable fluid supply and drainage via connected hoses.
The HPU electrical control panel is mounted adjacent to the HPU and incorporates the following controls and alarms:
The pump unit power circuits feature starter current limiting devices.
