Pflow Automated Systems provide an efficient, reliable way to transport materials in an automated manufacturing or warehousing operation. These systems are custom designed to fit your exact application needs. Pflow Automated Systems range from simple two-level applications to sophisticated multi-level, multi-directional systems. Pflow Automated Systems provide both vertical and horizontal conveying means.
- Load capacities up to 15,000 lbs.
- Standard carriage sizes to 10 ft. x 12 ft.
- Flexible loading/unloading patterns.
- PLC based controls.
- Tilt-deck, roll handling and cart handling systems are available.
Pflow Industries has over 25 years experience in engineering fully automated systems and hundreds of successful applications. Pflow offers complete single source responsibility for system design, installation and total support for all components including conveyors, VRCs and programmable controls.
Pflow Industries has the engineering capabilities, experience and technical know-how to solve a myriad of vertical lifting problems. We have designed vertical lifts to move materials that weigh 10 lbs. to over 100,000 lbs…with carriages from 30 x 30 inches to 30 x 30 feet…vertical heights from 4 ft. to over 200 ft. We have built large load work platforms, over and under equipment for assembly lines, hopper transfer systems and more. Pflow offers complete single source responsibility for system design, installation and total support for all components including conveyors, VRCs, and programmable controls. If you are faced with a difficult or unusual vertical lifting application, call Pflow. Whatever the size, speed and vertical height your application demands – we’ll help you develop the best solution.
Here are a few of the Special Vertical Lifts we have designed and installed:
Fully automated, high-speed system designed to catch large paper rolls that are discharged from a paper machine and transfer rolls down to a shipping area. Solution had to meet high throughput, high frequency, heavy load requirements (9000 lb. rolls., x 30 rolls per hour., x 24 hours per day., x 350 days per year). VRC is equipped with a cushioning device to catch paper rolls and a customized V-shaped carriage that tilts to load and unload rolls. Lift is an integral part of the paper production line, designed to run round the clock with no downtime.
Fully automated system features two Pflow VRCs connected by 75 ft. of roller conveyor, installed inside an existing tunnel. System incorporates a reversing system to accommodate outbound loads and returned empty containers. VRCs handle both infeeding and discharging of loads. Specially designed transfer cars move odd sized, heavy loads. System includes load buffer zones at each end of the tunnel. Photoeyes monitor positions to track outbound and returned containers. System eliminated manual labor, doubled throughput, and provided a safer way to move parts from the auto parts foundry to the shipping area.
Company needed to assemble extremely large, heavy fuel cell components and solve related vertical lifting problems. Pflow designed a system that incorporates two vertical material handling devices. Lift #1, which incorporates a screw lift mechanism, lowers a 90,000 lb. piece below grade level. Lift #2 lifts a 20,000 lb. piece, traverses the piece sideways and then lowers it on top the 90,000 lb. piece. After the two elements are assembled together, Lift #1 then raises the resulting 110,000 lb. load back to grade level for shipping.
30,000 lb. capacity, 4-post Pflow VRC custom designed to raise a 24,000 lb. scrap charge bucket, mounted on a transfer car, to an elevated runway track. Charge bucket is then moved horizontally on the runway track to any one of three induction melting furnaces. Scrap load is then automatically discharged into a furnace charge car. After load is discharged, charge bucket is returned to scrap make-up area for reloading. System is operational 16 hours per day. During operation, a scrap load is lifted and moved every 6 minutes.
Specially engineered 4-post VRC lifts odd sized carts that carry fragile aircraft wing parts up 20 ft. to a mezzanine. Carriage had to accommodate a shallow floor pit and had to be built with asymmetrical bracing to provide less than 1 inch of deflection. Carriage measures 10 ft. x 40 ft. and is equipped with solid steel guards to withstand impact of tow trucks and carts while they are backed into position onto lift. VRC moves entire load (tow truck, cart and wing parts) 10 times per day up to mezzanine.
