HYDRA4 Adaptive Drive
The HYDRA4 has four axes of movement designed to adapt to the hull of your boat. It operates on boat ramps up to 9º (1:6.3 gradient or 16% slope) and is powered by two High Torque Hydraulic Motors, with a marine grade two-part polyurethane enamel coating – certified to withstand 500 salt fog hours.
The ABL2500 can be fitted to your new or existing wobble-roller boat trailer. The Drive System fixes to the trailer frame – placement depending on the geometry of your hull. The Power Unit fixes to the winch end of your trailer in a protective enclosure.
HYDRA4 Power Unit
The HYDRA4 Power Unit includes the high-output 1600W Bosch Rexroth Hydraulic Powerpack and wireless control interface. The durable, marine grade enclosure can be securely located in a range of positions on the trailer. The Unit is controlled by a worldwide RF compliant radio and remote.
Ultra Grip Belt
The non-marking Ultra Grip Belt delivers the traction that enables the HYDRA4 to drive your boat up safely without damaging your hull. The drive and belt system are designed to load both fibre glass (GRP) or aluminium hulls.
