They are less energy efficient as the pump works against gravity to push the car and its passengers upwards; this energy is lost when the car descends on its own weight. The high current draw of the pump when starting up also places higher demands on a building\u2019s electrical system.<\/p>\n<h2>Cylinder replacement<\/h2>\n<p>Elevator cylinder replacements are completed due to cylinder failure or mandatory requirements by a municipality.\u00a0 Prior to 1972 the elevator code did not acknowledge the necessity of a safety bulk head so many elevators may have been installed without a safety bulk head.\u00a0\u00a0 If an elevator is not installed with a safety bulk head [two bottoms] there is a potential for catastrophic failure which can cause injury or death.\u00a0 For more information on cylinder replacement please click on our cylinder information brochure.<\/p>\n<p><a href=\"https:\/\/www.colleyelevator.com\/wordpress\/wp-content\/uploads\/2017\/04\/CylinderReplacement.pdf\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" class=\"aligncenter wp-image-246 size-full\" src=\"https:\/\/www.colleyelevator.com\/wordpress\/wp-content\/uploads\/2016\/11\/cylinder-thumb.jpg\" alt=\"cylinder-thumb\" width=\"232\" height=\"300\" srcset=\"https:\/\/www.colleyelevator.com\/wordpress\/wp-content\/uploads\/2016\/11\/cylinder-thumb-200x259.jpg 200w, https:\/\/www.colleyelevator.com\/wordpress\/wp-content\/uploads\/2016\/11\/cylinder-thumb.jpg 232w\" sizes=\"(max-width: 232px) 100vw, 232px\" \/><\/a><\/p>\n<p style=\"text-align: center;\">Click The Thumbnail To Open Our Cylinder Replacement Brochure in PDF Format(2800kb)<\/p>\n<p style=\"text-align: left;\">If building owners are interested in having Colley Elevator complete the elevator modernization please call <strong>630-766-7230, <\/strong>email<strong> sales@colleyelevator<\/strong>\u00a0or fill out our <a href=\"https:\/\/www.colleyelevator.com\/wordpress\/contact\/\">contact form<\/a>.<\/p>\n<\/div><div class=\"fusion-clearfix\"><\/div><\/div><\/div><\/div><\/div><div class=\"fusion-fullwidth fullwidth-box fusion-builder-row-2 mailing-section nonhundred-percent-fullwidth non-hundred-percent-height-scrolling\" style=\"--awb-border-sizes-top:0px;--awb-border-sizes-bottom:0px;--awb-border-sizes-left:0px;--awb-border-sizes-right:0px;--awb-border-color:#3e3e3e;--awb-border-radius-top-left:0px;--awb-border-radius-top-right:0px;--awb-border-radius-bottom-right:0px;--awb-border-radius-bottom-left:0px;--awb-padding-top:24px;--awb-padding-right:24px;--awb-padding-bottom:24px;--awb-padding-left:24px;--awb-margin-top:24px;\" ><div class=\"fusion-builder-row fusion-row\"><div class=\"fusion-layout-column fusion_builder_column fusion-builder-column-1 fusion_builder_column_1_1 1_1 fusion-one-full fusion-column-first fusion-column-last\" style=\"--awb-bg-size:cover;\"><div class=\"fusion-column-wrapper fusion-flex-column-wrapper-legacy\"><div class=\"fusion-sep-clear\"><\/div><div class=\"fusion-separator fusion-full-width-sep\" style=\"margin-left: auto;margin-right: auto;width:100%;\"><\/div><div class=\"fusion-sep-clear\"><\/div><div class=\"fusion-title title fusion-title-1 fusion-sep-none fusion-title-center fusion-title-text fusion-title-size-three mailing-header\" style=\"--awb-margin-top:10px;--awb-margin-bottom:10px;\"><h3 class=\"title-heading-center\" style=\"margin:0;\"><h3 style=\"text-align: center;\">Get on the mailing list<\/h3><\/h3><\/div><div class=\"fusion-aligncenter\"><a class=\"fusion-button button-flat button-medium button-custom fusion-button-default button-1 fusion-button-default-span fusion-button-default-type mailing-submit-btn\" style=\"--button_accent_color:#000000;--button_border_color:#000000;--button_accent_hover_color:#ffffff;--button_border_hover_color:#ffffff;--button_gradient_top_color:#d3d3d3;--button_gradient_bottom_color:#d3d3d3;--button_gradient_top_color_hover:#090040;--button_gradient_bottom_color_hover:#090040;\" target=\"_self\" href=\"http:\/\/www.colleyelevator.com\/mail-subscription\/\"><span class=\"fusion-button-text\">Subscribe to Our Newsletter<\/span><i class=\"fa-envelope far button-icon-right\" aria-hidden=\"true\"><\/i><\/a><\/div><div class=\"fusion-clearfix\"><\/div><\/div><\/div><\/div><\/div>\n<\/p>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":3,"featured_media":0,"parent":49,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"class_list":["post-58","page","type-page","status-publish","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.9 -
