A homeowner or villa builder is working with a different set of constraints: a 2\u20133 story shaft, a fixed pit depth already poured (or not poured yet), single-phase household power, and a strong preference against a dedicated machine room eating into a spare bedroom or attic. The two technologies still trade off the same way \u2014 pressure versus rope, no counterweight versus counterweight-free steel belt \u2014 but the deciding variable in a home is almost always shaft geometry, not throughput.<\/p>\n<p><img decoding=\"async\" class=\"\" src=\"https:\/\/jdrkcn.com\/wp-content\/uploads\/2025\/07\/1_0000_6.webp\" width=\"635\" height=\"635\" \/><\/p>\n<h2>Hydraulic Elevators: How the JDRK Home\/Villa Unit Works<\/h2>\n<p>JDRK&#8217;s Home\/Villa <span style=\"color: #ff6600;\"><strong><a style=\"color: #ff6600;\" href=\"https:\/\/jdrkcn.com\/ru\/\u043a\u0430\u0442\u0435\u0433\u043e\u0440\u0438\u044f\/\u0433\u0438\u0434\u0440\u0430\u0432\u043b\u0438\u0447\u0435\u0441\u043a\u0438\u0439-\u043b\u0438\u0444\u0442\/\">\u0413\u0438\u0434\u0440\u0430\u0432\u043b\u0438\u0447\u0435\u0441\u043a\u0438\u0439 \u043b\u0438\u0444\u0442<\/a><\/strong><\/span> lifts the cabin using pressure from an imported high-precision proportional valve and lowers it by gravity, with stepless speed regulation rather than fixed gear steps.

They aren&#8217;t. A hydraulic system&#8217;s proportional valve and oil reservoir still need a placement point near the shaft base, and that reservoir is a wear component with its own service interval \u2014 something a traction system&#8217;s motor-and-belt assembly doesn&#8217;t carry. Conversely, a traction system&#8217;s counterweight travels inside the shaft for the life of the elevator, which is dead space a hydraulic shaft doesn&#8217;t need to reserve. Neither system is simply &#8220;better&#8221; \u2014 they shift the space and maintenance cost to different places, and which one costs you less depends on whether your constraint is ceiling height or shaft width.<\/p>\n<h2>Which One Fits Your Site?<\/h2>\n<ol>\n<li>Measure the clearance above your top landing. If it&#8217;s near or under 2,600 mm, the hydraulic line is the one built around that limit; confirm the traction unit&#8217;s clearance requirement with <span style=\"color: #ff6600;\"><strong><a style=\"color: #ff6600;\" href=\"https:\/\/jdrkcn.com\/ru\/\u0441\u0432\u044f\u0437\u0430\u0442\u044c\u0441\u044f-\u0441-\u043d\u0430\u043c\u0438\/\">JDRK<\/a> <\/strong><\/span>directly, since it isn&#8217;t in the current published spec sheet.<\/li>\n<li>Check your pit depth. A shallow or zero pit points toward the hydraulic elevator&#8217;s 150 mm-or-less option.<\/li>\n<li>Confirm your available power. If you only have single-phase 220V and want a documented ~1.5 kW draw, the traction unit&#8217;s numbers are already published; ask for the hydraulic line&#8217;s power draw if that&#8217;s your limiting factor.<\/li>\n<li>Decide how much shaft width you can spare. A counterweight-free hydraulic layout reclaims more of a narrow shaft; a traction layout needs to account for counterweight travel.<\/li>\n<li>Weigh long-term maintenance against upfront mechanical complexity \u2014 oil\/valve servicing versus a belt system JDRK rates for 2\u20133x the life of steel rope.<\/li>\n<\/ol>\n<h2>Certifications and Standards<\/h2>\n<p>Both product lines carry the same company-wide certification marks: SGS, SGC, SGRZ, CNCA, CNAS, and ISO 9001, a globally recognized quality management system standard. Product pages also reference CE marking (the EU&#8217;s conformity standard) and ASME, the American Society of Mechanical Engineers&#8217; equipment standards body. Certificate numbers and issuing-body registration details aren&#8217;t published on the current site, so treat these as company-stated compliance claims rather than independently verifiable certificate records until confirmed.<\/p>\n<h2>Pricing<\/h2>\n<p>JDRK does not publish pricing for either the hydraulic or traction line \u2014 every product page routes to a quote request instead of a listed price. If budget is your first filter, request a quote with your shaft dimensions, pit depth, and top clearance already measured; that&#8217;s the information JDRK&#8217;s team needs to price a residential unit accurately.<\/p>\n<h2>FAQ<\/h2>\n<h3>Q: Does a traction elevator always need more headroom than a hydraulic one?<\/h3>\n<p>A: Not necessarily \u2014 headroom depends on the specific machine-room-less design, not the drive type alone. JDRK&#8217;s traction clearance figure isn&#8217;t published yet, so this needs project-specific confirmation rather than a general rule.<\/p>\n<h3>Q: Can a hydraulic elevator go in a home with no pit at all?<\/h3>\n<p>A: JDRK offers a zero-pit configuration for the Home\/Villa <span style=\"color: #ff6600;\"><strong><a style=\"color: #ff6600;\" href=\"https:\/\/jdrkcn.com\/ru\/\u043a\u0430\u0442\u0435\u0433\u043e\u0440\u0438\u044f\/\u0433\u0438\u0434\u0440\u0430\u0432\u043b\u0438\u0447\u0435\u0441\u043a\u0438\u0439-\u043b\u0438\u0444\u0442\/\">\u0413\u0438\u0434\u0440\u0430\u0432\u043b\u0438\u0447\u0435\u0441\u043a\u0438\u0439 \u043b\u0438\u0444\u0442<\/a><\/strong><\/span>, alongside a shallow-pit option down to about 150 mm, so a pitless install is possible depending on the site.<\/p>\n<h3>Q: Which one uses less power day-to-day?<\/h3>\n<p>A: JDRK publishes the traction unit&#8217;s draw at roughly 1.5 kW total on standard 220V single-phase power. The hydraulic unit&#8217;s power draw isn&#8217;t in the current spec sheet, so a direct comparison needs a quote request.<\/p>\n<h3>Q: Is a machine room ever required for either type?<\/h3>\n<p>A: No \u2014 both JDRK lines are machine-room-less by design, using either a proportional valve system (hydraulic) or a backpack\/gantry motor mount (traction) instead of a rooftop plant room.<\/p>\n<p>If you already have your shaft measurements, JDRK&#8217;s team can confirm which drive type fits before you finalize the retrofit plan.<\/p>","protected":false},"excerpt":{"rendered":"<p>Jiade (Shandong) Elevator Co., Ltd.
