It is a unique mobility product from people who understand that multiple floors don’t have to be an obstacle. Symmetry’s philosophy is “more space for living.” That’s why we designed platform lifts that take up less room and seamlessly fit into any style of home or commercial application. Even when they blend in, Symmetry platform lifts stand out with simple operation, reliable function, and options that are virtually limitless. Commercial or Home Installation An unenclosed vertical lift requires little or no site modifications and is an ideal accessibility solution when space and costs are the primary concerns. They are commonly used in public facilities when the travel does not exceed 60” and private residences at travel heights up to 144”. An enclosed vertical lift requires slightly more space and is used in public and private facilities at travel heights up to 144”. A shaftway vertical lift is designed for enclosed shaftway applications, including floor penetration, in public and private facilities at travel heights up to 144”. Meets ADA Requirements Vertical lifts are approved in the ADA Accessibility Guidelines as a means to provide unassisted entry and exit from buildings, service or recreational facilities. Built in accordance with ASME A18.1. Check with your local Symmetry provider to determine if additional State or local approvals or travel height restrictions are required. 3 VPC-UL (Unenclosed Lift) VPC-SL (Shaftway Lift) VPC-EL (Enclosure Lift) General Rules for VPC Applications: These rules have been developed as a guideline and are based on the information supplied in ANSI A117.1-2009 and ASME A18.1-2008. Please consult your local authority having jurisdiction regarding local codes and regulations. PLATFORMS: - 30”x 48” minimum clear space on platform for most applications. - If the VPC exits 90 degrees from an entry point the clear space must be 42” x 60”. DOORS AND GATES: - 32” minimum clear opening for a door or gate accessing the VPC from the end. - 42” minimum clear opening for a door or gate accessing the VPC from the side. - All doors/ gates require a minimum 18” latch side clearance. A greater distance may need to be provided as described in ANSI A117.1-2009. - Power assisted doors/gates are required in all applications that are not straight through. This includes all applications servicing more than 2 landings. - Gates must be a minimum 42” tall. - Doors must have 80” clear inside height. - Doors/gates must be installed flush to the interior of the hoistway. - In unenclosed commercial applications a traveling gate mounted to the platform, in conjunction with a safety pan (under platform safety device), is required. - In unenclosed residential applications less than 60” in travel height an automatic folding ramp may be used in lieu of a platform gate. LIFT HEIGHT: - Unenclosed commercial applications cannot exceed 60” in travel height. - Unenclosed residential applications are available at travel heights not to exceed 168”. - Shaftway and enclosure applications, both commercial and residential, are available at travel heights not to exceed 168”. - Some State and local jurisdictions have additional travel height restrictions. RAMPS: - Stationary end ramps will project 25” from either the edge of the running clearance (for models with a platform gate) or the outside face of the lower landing door or gate. - Automatic folding ramps will project 15” from the edge of the platform on the lower landing side of the lift. - Stationary side ramps will project a minimum of 25” from the outside face of the lower landing door or gate. PITS: - The minimum depth of a pit for a VPC will be 2 1/2”. A 3” pit is recommended. - When a VPC is installed in a pit and in an outdoor application the pit must have a drain. ANCHORING: - The machine tower must be anchored to a wall, unless the travel height is less than 60”. - The machine base must be anchored to the floor. - Doors and gates are not free-standing and must be anchored vertically and horizontally. RUNNING CLEARANCES: - The running clearance on a side of the lift that will be used to enter/exit the lift must be 3/8” minimum to 3/4” maximum. - The running clearance on a non-opening side of the platform must be 2” minimum. 4 COMPONENT IDENTIFICATION Straight Through Configuration Unenclosed Unit Upper Gate Support & Barrier (Required and Provided by others) Upper Landing Gate Assembly Sidewall Panels Under Platform Safety Pan Assembly Ramp Required for Floor Mount Models (Non Pit Mount) Automatic Folding Ramp Shown LED Diagnostic Board (located under main tower cap) Upper Bearing Mount Drive Motor 115V or 230V Controller Box Acme Screw (Not Visible) Limit Switch Carriage, with Lift Nut & Safety Nut Lower Bearing Mount Lower Landing Platform Gate Assembly Folding Ramp Actuator Platform Controls Tower Assembly View from behind machine tower with rear cover removed. 5 UNENCLOSED DESIGN - STRAIGHT THROUGH Lower Landing Pit Mount, Stationary Ramp, & Flip Up Ramp Applications shown.
