Corrosive washdown agents and strict hygiene standards destroy carbon steel lifters in food processing plants. This Z-type continuous vertical conveyor features full SUS304 food-grade construction, elevating 30 kg milk powder containers and ingredient boxes at rates above 6 units per minute across a 5.2 meter vertical rise.
Full SUS304 Construction: Non-corrosive stainless frame and slat chains withstand daily chemical washdown routines.
Continuous Z-Flow Routing: Infeed and discharge at 1000 mm elevation sustain 360 units per hour.
Modular Knockdown Build: Sectional column engineering enables installation through narrow cleanroom access portals.

The four-column vertical mast uses solid SUS304 structural square tubing with brushed sheet metal lower cladding and stainless wire mesh upper enclosures. Carrier platforms use SUS304 slat bars mounted to precision stainless steel roller chains, resisting corrosion from lactic acid, moisture, and alkaline detergents. Solid stainless steel drive sprockets and low-friction UHMW-PE chain wear strips prevent metal-on-metal shedding, maintaining clean air quality in dairy processing zones.
The main drive uses an IP55 washdown-rated helical gearmotor paired with an Inovance variable frequency drive for controlled acceleration. Inspection access panels along the lower stainless shroud allow quick chain tension verification and guide track review without removing external safety cages. GRADIN provides a 12-month complete mechanical and electrical warranty, sanitary spare chain assemblies, and full technical documentation for local maintenance teams.
Integrated 600 mm stainless steel powered roller conveyors at infeed and outfeed stations transfer 400×600×250 mm cartons without manual pusher mechanisms. The entire unit disassembles into modular column sections, allowing passage through standard plant entry doorways before on-site bolt assembly. For facilities that manage palletized staging next to vertical conveyors, plant managers can implement cleanroom stainless lift tables to align container feeds.
Perimeter stainless steel wire mesh guards isolate moving slat platforms from operators across all vertical tiers. Optical photo-eye sensors at load portals halt chain drive motion if box misalignment or product overhang occurs. The equipment complies with international hygiene and machinery directives:
ASME B20.1 Safety Standard for Conveyors and Related Equipment
OSHA 1910 Machine Guarding Regulations for Power Transmission Apparatus
FDA 21 CFR Part 110 Current Good Manufacturing Practice in Manufacturing, Packing, or Holding Human Food
CE Machinery Directive 2006/42/EC compliance for continuous vertical conveying machinery
Dairy Powder Processing: Vertical transfer of 30 kg milk powder cartons and ingredient bags from ground formulation rooms to upper blending hoppers.
Infant Nutrition Packaging Lines: Continuous elevation of sealed raw material tubs into positive-pressure cleanroom filling suites.
Meat & Poultry Box Handling: Moving packaged protein cartons across washdown corridors between chillers and packing decks.
Pharmaceutical Batch Transfer: Elevating sterile active ingredient containers to secondary compounding mezzanines.
Confectionery Ingredient Feeds: Transfer of bulk cocoa, sugar, and starch boxes to elevated cooker platforms.
Cleanroom Packaging Buffer Lines: Continuous elevation of plastic bottles and containers between blow-molding and clean filling zones.
For this heavy-duty series, we can engineer load capacities up to [300] tons, with platform dimensions and lifting heights customized to your operational envelope. Requirements exceeding our standard engineering matrix will undergo a Finite Element Analysis (FEA) by our engineering team to ensure structural viability before proposing a solution.
To initiate the engineering proposal, please provide the following baseline data:
Rated Load Capacity
Maximum Lifting Height & Closed Height
Platform Dimensions (L x W)
Duty Cycle (e.g., operational cycles per hour/day)
Environmental Conditions (e.g., indoor/outdoor, washdown, explosion-proof)
Pit depth or overhead clearance constraints
Yes. The control systems can be equipped with standard communication protocols (e.g., Profinet, Modbus, Ethernet/IP) utilizing [Siemens / Allen-Bradley / Omron] PLCs. This ensures seamless I/O signal synchronization with upstream/downstream conveyors, AGV/AMR units, and your central control room.
Every custom unit undergoes a mandatory Factory Acceptance Test (FAT) prior to dispatch. This includes continuous operational testing at 100% rated load, static overload testing at [120% / 125%] capacity, and the physical triggering of all mechanical anti-fall and hydraulic safety interlocks. FAT documentation and video proof are included in your engineering package.
Upon final approval of the General Arrangement (GA) drawings, the manufacturing lead time is typically 4 to 8 weeks. Oversized structural components are engineered with a modular design to fit into standard shipping containers (20FT/40HQ). On-site assembly utilizes pre-engineered bolted flange connections and heavy-duty aviation plugs, strictly eliminating the need for field welding.
We provide a standard [12/24]-month warranty covering the structural frame and primary hydraulic/electrical components. To minimize operational downtime, a comprehensive set of standard consumables (e.g., cylinder seal kits, travel switches, relays) is shipped alongside your equipment. During the warranty period, replacement parts for non-human-induced failures are dispatched via priority air freight (DHL/FedEx) within 48 hours.
Beyond the warranty, we guarantee lifetime engineering support. Your custom equipment's CAD drawings, electrical schematics, and BOM (Bill of Materials) are permanently archived in our system. This ensures you receive uninterrupted remote troubleshooting, maintenance guidance, and exact spare parts matching for the entire lifecycle of the equipment.
