Ideal for high- speed applications that require lifting boxes, cartons, packages, totes, containers or cases. GENERAL Principal components of the DB Series are guide columns, carriage and mechanical actuating mechanism. All components are pre-assembled for ease of installation. STRUCTURE Frame is constructed of structural steel, and designed to be self-supporting. Carriage is typically supplied with powered roller conveyor deck. Carriage is a cantilever design, and can be loaded from any of three operating sides, depending on the application. OPERATION Carriage is lifted and lowered by dual chains connected to electric motor-reducer assembly. Power unit employs a fractional HP brake motor mounted to top of lift frame. ELECTRICAL Standard power requirements are 230V/460V, 3-phase. Control voltage is 110VAC. Standard push button stations and control panel are NEMA 12 rated. Control panel is designed to be mounted to back of frame; all control devices are pre-wired by manufacturer. A variety of control options are available, from basic interface to PLC automated controls. SAFETY FEATURES Travel of the carriage is controlled by a limit switch. When the switch is tripped or power is lost, the motor shuts off and the mechanically actuated brake is engaged. Overload and carriage over-travel protection is provided. SAFETY ENCLOSURES / GATES Standard units include integral, full-height enclosures on all sides made of 1/2” expanded metal. See page 23 for additional information. 21 •Lifts loads up to 100 lbs. •Standard carriage size is 3’ x 3’. •Standard travel speed is 60 FPM. •Indoor use only. •Loading and unloading accessible from three sides.•Saves space by handling loads often transported on an inclined conveyor. •Smooth, quiet counterweight lifting mechanism minimizes horsepower requirements and saves energy. •Completely self-contained, self-supporting and economical. •Durable, high-quality materials and design ensure safe, reliable long-term performance.

Code approved, space efficient, and built for maximum protection and performance. PFlow safety gates are equipped with a mechanical lock and electric contact, meeting code requirements for manual loading applications. Enclosures Built to Protect and Last •PFlow standard panels are 6” to 5’ wide. •Panels are painted PFlow Blue. Custom paint colors available upon request. •All mounting hardware included. •Non-standard sizes, custom finishes and galvanized panels available upon request. Required Design Standards for Lifts and Gates All accessible sides of a unit not used for loading or unloading must be protected by enclosures at least 8’ high, and capable of rejecting a ball 2” in diameter at each level. Any combination of shaftways, walls or permanent enclosures that provide equivalent protection is acceptable. If lift service is to the edge of a mezzanine or balcony, only minimal enclosures are required because the equipment is guarded by location. Fire Code Requirements If a floor is penetrated, contact your insurance company or local fire authorities to determine if a fire-rated enclosure is required. Optional Visual Safety Barrier Additional safety at upper most level can be provided when the access gate is open and the carriage is not present. Shaftway Applications When a VRC is penetrating floors that are rated due to fire breaks or environmental conditions, walls and doors configured by others to meet the required conditions may be required. The term typically used is “shaftway.” PFlow VRCs can regularly be found behind interlocked doors in new installations, or replacing freight and service elevators, ash lifts, dumbwaiters and other lifting devices. PFlow enclosures are code approved and made of ½” flattened expanded metal for superior strength and longevity. 23 Single & Bi-Parting Swing Gates •Standard single and bi-parting swing gates provide 7’ 0” H load clearance. •Maximum single panel width: 6’ W (overall) mounted on a 5’ 0” W carriage. •Standard bi-parting panel width: Up to 11’ 0” W (overall) mounted on a 10’ 0” W carriage.

It’s no surprise. With the largest engineering team in the industry, and a culture focused on innovation, PFlow continues to create new breakthroughs in vertical lift performance and safety. Quantum Drive Exceptional performance, durability, increased capacity and faster speeds! This quantum leap in chain-driven technology features reduced vibration and less maintenance. Patent pending. Certified Safety Cams •In the unlikely event of a lifting chain break, the safety cam will immediately and automatically rotate into position. •Safety cams are mounted on the carriage and positioned between the flanges of the guide column. •Spring-loaded and designed with a series of hardened teeth. As the safety cams rotate into position, the downward pressure of the carriage forces them into the flanges of the guide columns, preventing carriage descent. When chain tension is returned to normal, the cams rotate back to their inoperative position, allowing the VRC to resume operation. On the M Series and F Series, slack or broken chain conditions are sensed by a switch on the chain tensioner assembly, which cuts power to the drive. All units should be fully inspected before resuming service. DeckLock This exclusive safety system protects workers, materials and machines by preventing uncontrolled carriage descent from upper levels due to overload or brake malfunction.COMMITTED TO SAFETY AND PATENTING INNOVATION Maintenance Pins (Optional) Optional, manually-actuated maintenance pins provide additional safety when performing service on the VRC. The pins extend under the carriage structure to provide one-way assurance that the VRC carriage is properly secured. Note: Two means to secure the carriage is normally required. 26 PFlow Patents 1 9,598,242 Moving floor system 2 8,789,661 Visual warning barrier for door assembly 3 8,328,003 Shopping cart conveyor with gate assembly 4 8,075,237 Multi-level vehicle lift 5 7,931,136 Jam sensor for shopping cart conveyor 6 7,779,992 Shopping cart conveyor system with pivoting lug 7 7,453,358 Shopping cart conveyor with gated access 8 7,131,532 Belt attachment device and method 9 6,896,125 Belt attachment device and method 10 6,644,210 Shopping cart conveyor/front wheel alignment/turning system 11 6,490,979 Inclined shopping cart conveyor system 12 6,394,260 Conveyor system including roller-guided carriage assemblies 13 6,360,848 Safety system for a vertical reciprocating conveyor 14 5,941,347 Portable lift 15 5,908,088 Hydraulic drive mechanism for a vertical conveyor 16 5,601,157 DeckLock 17 5,408,789 Overhead security door 18 5,228,537 Safety mechanism for a vertical reciprocating conveyor 19 5,205,379 Vertical conveyor 20 4,987,992 Material transfer apparatus 21 4,227,463 Apparatus for removing and installing batteries Moving Floor System High productivity, coupled with improved safety, are built into this ultra-efficient moving floor assembly line. The flexible design especially lends itself to assembly of large machinery. DeckLock System (Optional) •Protects workers, materials and machines by eliminating accidents caused by carriage drop. •High-capacity DeckLocks automatically extend to prevent uncontrolled descent at critical upper levels. •Ensures safe loading and unloading with a forklift. •Prevents uncontrolled descent in the case of overload or brake malfunction during loading/unloading operations. •Gate-operated mechanical, pneumatic and electric versions available. •Can provide absolute positioning if required. PFlow VRCs are built with a substantial safety factor, but inadvertent overload or lack of maintenance can result in dangerous, unintentional carriage descent. Mechanical VRCs depend upon spring-set brakes to maintain the carriage position. These brakes are sized to provide a minimum of 150% of maximum load capacity; however, wear and lack of brake maintenance can reduce that capacity. Overload of the carriage can cause brake slippage. The exclusive PFlow patented DeckLock system provides additional safety under these conditions. Vehicle Display System Car shopping reaches new heights with this innovative structure, which is custom built for vehicles from small cars to large buses. Vehicles are loaded and unloaded with minimal labor and maximum exposure.P (414) 352 9000 F (414) 352 9002 PFlow Industries, Inc. 6720 N.
