2.8 Location and mounting requirements

Hydraulic ram

Location and mounting requirements:

• MUST be mounted on a very solid structure (for example, a
substantial frame member of your vessel). The drive produces a
considerable amount of force, so you MUST ensure that both the
structure and your tiller arm or rudder quadrant can cope with the
peak levels of thrust stated in the Technical Specification in this
document. In some cases it may be necessary to build a specially
strengthened frame to mount the drive unit. Consult the steering
gear manufacturer if you have any doubt about the strength of the
tiller arm or rudder quadrant.
• The Type 2 drive may be mounted horizontally or vertically.
• The Type 3 drive MUST be mounted horizontally with its mounting
foot on a horizontal surface. The swivel joint does NOT have
sufficient movement to position the foot vertically.
• The hydraulic ram must NOT foul any part of the vessel's structure
or quadrant throughout its entire range of movement.
• MUST be mounted in a location allowing sufficient clearance for
the mounting pin to be removed if required.
• MUST be mounted with sufficient clearance at the rear of the ram
unit for the hydraulic pipes. You must allow at least 17 cm (6.7 in)
clearance at the rear of the unit for the extruding pipes.
• MUST be fitted in a dry area, free of bilge water (the ram is NOT
waterproof).
• MUST be accessible for future servicing.
• The supplied M8 bolts and washers are suitable for mounting
the hydraulic ram to a surface between 1.2 cm (0.47 in) and 2.4
cm (0.94 in) thick. Larger bolts and washers are required for
a thicker surface.
