WESMAR Soundome Long Stroke Hoists

Which Hoist to choose?

WESMAR offers a number of hoist systems (brochure pdf) to fit your vessel. You have several options depending on the sonar frequency you need and the size of the seachest in your vessel. Headroom above the seachest and the location of the seachest are important considerations. Please consult WESMAR and/or your marine architect for more information.

Advantages of hydraulic hoists

WESMAR is the only manufacturer of sonars to offer hydraulic hoists. Hydraulic hoists can lower the sonar transducer by up to 1.5 meters below bubble level into clean water. Another advantage is that you can raise and lower the transducer in as little as 5 seconds, several times faster than conventional hoists. With a WESMAR long stroke hydraulic hoist it is possible to install a sonar on a side of the keel without expensive fairings. WESMAR heavy duty hydraulic hoists are virtually vibration free which increases the sonar performance in heavy seas.

Replacement hoists

WESMAR hoists can be purchased separately of transducers. Scientific transducers, sounder transducers and older sonar transducers can be fitted to the new WESMAR hydraulic hoists to dramatically improve their performance. Please consult WESMAR for more information.

M8 Hoist

Heavy Duty, Vibration-free, Self-contained Hydraulic Hoist. WESMAR’s rugged hydraulic hoist system extends the soundome up to 125% deeper in the water providing maximum performance, free from vessel noise. The soundome tube on the M8 sonars is more than twice the size of other systems and at 4 inches in diameter it provides stable, vibration-free performance.

WESMAR is the only manufacturer of scanning sonars to offer this option. If you are installing the sonar on a side of the keel, the M8 hoist is the way to make sure the sonar will see on the other side of the keel.

Hydraulic power pack assembly requires no maintenance and comes fully assembled from the factory. Only an electrical connection is required, no complicated plumbing.

The M8 hoist can also be supplied with an emergency lift screw system. Available with HD800/60-8-M8or HD800/110-8-M8. Long stroke versions also available.

FT Hoist
