Transporting palletized raw materials across multi-story cleanrooms and washdown production zones leads to rapid corrosion and particulate contamination when using standard painted freight lifts. This custom stainless steel hydraulic goods lift features full SUS304 carriage cladding, washdown bi-parting landing doors, and sealed hydraulic actuators engineered for high-hygiene vertical logistics.
Sanitary SUS304 Construction: Non-porous stainless steel cabin and door assemblies prevent bacterial harboring and corrosion.
Multi-Floor Precision Leveling: Microprocessor-controlled proportional valves achieve ±3 mm landing accuracy across multiple floors.
Interlocked Bi-Parting Gates: Mechanical and electrical interlocking prevents floor gate operation unless the carriage docks.

The lift carriage interior is lined with 2.0 mm food-grade SUS304 (optional SUS316L) stainless steel panels with brushed No. 4 sanitary finishes, eliminating painted surfaces prone to flaking or chemical degradation. Dual direct-acting or 2:1 ratio hydraulic lifting cylinders feature heavy chrome-plated micro-honed rods housed within corrosion-resistant telescopic guide sleeves. Floor framing utilizes high-tensile structural steel coated with chemical-resistant two-pack epoxy beneath the stainless steel cladding, preventing structural deflection under concentrated electric pallet jack and forklift wheel loads up to 5,000 kg.
The external electro-hydraulic power station is housed in a standalone IP65 stainless steel enclosure, isolating hydraulic fluids, valves, and electrical relays from humid or washdown cleanroom atmospheres. Modular self-lubricating polymer guide rollers eliminate the need for open grease on the mast rails, maintaining strict ISO Class 5–8 air particulate requirements. GRADIN provides a 12-month complete component warranty, comprehensive maintenance schedules, sanitary seal replacement kits, and lifetime remote engineering troubleshooting.
Flush-mounted stainless steel call-and-send control panels with digital floor position indicators and emergency stop buttons are integrated at every landing door frame. The bi-parting landing doors combine upper stainless tubular grilles for visual line-of-sight with solid lower impact panels, operating via smooth manual swing hinges or optional automated push-button operators. For localized ergonomic workstation lifting at production lines, facilities can integrate complementary stainless cleanroom lift tables to synchronize material transfer.
Fail-safe hydraulic velocity fuses seated directly into cylinder ports lock fluid instantly in the event of hydraulic line rupture, halting the carriage immediately. Electrical and mechanical interlocks on all landing doors prevent gate opening while the platform is in transit, and isolate lift actuation if any gate remains unlatched. The equipment strictly complies with international sanitary and industrial safety directives:
OSHA 1910 Material Handling Regulations for Fixed Industrial Lifting and Guarding
ASME B20.1 Safety Standard for Vertical Conveyors and Material Lifts
ISO 14644-1 Cleanroom and Associated Controlled Environments Standards
CE Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU
Pharmaceutical Cleanrooms: Vertical pallet transfer of active pharmaceutical ingredients (API) and sterile packaging between ISO-classified cleanroom suites.
Food & Beverage Processing Facilities: Transporting raw ingredients, stainless dough vats, and packaged consumables across multi-level washdown preparation floors.
Semiconductor & Electronics Fabrication: Particle-free vertical movement of sensitive wafer cassettes, chemical totes, and automated equipment modules.
Chemical & Hazardous Material Plants: Vertical staging of corrosive chemical drums and liquid containers in demanding atmospheric environments.
Biotechnology Laboratories: Secure material transfer between multi-tiered containment laboratories requiring daily sanitization and chemical washdown.
Cosmetics & Personal Care Manufacturing: Moving liquid batching tanks and finished product pallets between formulation mezzanines and packaging floors.
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.
