I would not suggest working to get all of your facets indexed unless you can take steps to ensure quality and unique content is presented. For example, the facet you provided shows the products filtered by load capacity, lift, etc. If all of your facets were crawled and indexed, you would end up with a large number of pages that simply have a single product listed, which would in turn compete with your single product page.
Additionally, as you are not adding any additional unique content onto the page to further highlight the facets that are selected.. for example "These lift tables are rated with lift capacity for 300kg and 500kg with a 480mm width." .. I doubt you would see any improved rankings or traffic as a result of indexing these facets.
Lastly, I'm not aware that the URL structure you have provided for the facets is actually navigable by search engines at this point. the # in the url typically creates a "break" in the url, with the crawlers parsing the content before, but after. This isn't to say that it isn't a work in progress or that crawler behavior would change (read: spiders get js now, flash, etc.). But if you want those urls to get crawled, I would suggest implementing pushstate to force seo friendly urls for each facet.. alternatively you could look at a solution leveraging the ? instead of # and = instead of : so the facets appear as query parameters.
Is it worth your time? Depends on whether you think you faceted pages have enough value and weighting that they could rank alone. It is also worth considering whether or not your faceted navigation is allowing for crawling of the paginated pages, therefore allowing full crawl/index of all of your products vs. only those available on the first page.
Good luck!
