Setting up hydraulic system on Meercat Workboat

I am setting up a new system on a Meercat Workboat. The pump is a load sensing piston pump attached to an engine. The load sensor maintains a constant flow regardless of the out put load. The pump maintains a 15Bar differential so if the load increases the pump swashplate will move and increase the flowrate thus maintaining this differnetial.
This system provides pressure and flow to a deck crane. The crane will move at a speed depending on the position of the hand levercontrol (moved by the operator) and will maintain this speed even if the load changes.
