We were looking at buying some hoists for our workshop & found the HAPP 4.5T 2 Post Hoist (HAPP45Pi) design & quality to be on par with that of the $8K Rotary SPOA10 hoists – the arm design was also very similar to that of the Rotary, so for a saving of over $4K the decision was simple. Not to mention, Gavan’s service & advice went way above & beyond that of any other supplier, and you can tell he really knows the technical in’s & out’s of his product designs
