Discharging heavy bulk pallets or bins of loose materials into elevated processing hoppers is a notoriously difficult, hazardous process. Standard material lifts only provide vertical elevation, forcing workers to manually scoop or tilt heavy bins at height, which triggers severe fall risks and muscular injuries. Furthermore, operating heavy hydraulics in freezing winter climates (down to -25°C) is a common failure point; standard hydraulic oil thickens rapidly, resulting in sluggish movement, valve blockages, and blown pump seals.
Gradin’s Hydraulic Lift and Tilt Platform completely automates this hazardous vertical-to-discharge workflow. Engineered as a specialized Bulk Material Unloading Lift, this unit lifts pallets to a mezzanine height of 6.3 meters before automatically executing a controlled tilt. Acting as an outdoor Low-Temperature Hydraulic Lift equipped with specialized oil heaters, it operates smoothly in sub-zero environments. Complying with ASME mechanical standards, this platform links directly with downstream silos.

Sequential Interlocking Dual-Pump System: We prevent disastrous operational crashing between lifting and tilting cycles. The Hydraulic Lift and Tilt Platform is driven by a specialized Dual-Pump Hydraulic System (comprising a 5.5kW lifting motor and a 4kW tilting motor) -> ensuring the platform must reach its exact upper level station and lock before the hydraulic tilt circuit can engage, and preventing any platform descent until the deck has completely reset to
0∘.
Thermostatic Hydraulic Oil Heating Assembly: Freezing sub-zero temperatures down to -25°C thickens standard oil, causing system seizures. Gradin integrates submersible thermostatic heating elements inside both pump reservoirs with analog temperature indicators -> keeping the hydraulic oil at its optimal viscosity during freezing winters to ensure instant, smooth startup response.
Heavy-Duty 150H Structural H-Beam Rails: Lifting 3-ton loads and tilting them at a high elevation places severe torsional force on guiding columns. Our 150H Steel Guide Rail Lifter frame is anchored directly to the concrete slab using heavy expansion bolts -> providing massive structural rigidity to absorb side-loading forces during the dump cycle.
Precise 60-Degree Tilting Platform Deck: Heavy bulk parts or viscous materials often cling to containers if the slide slope is too shallow. The integrated 60-Degree Tilting Platform uses dual high-torque cylinders to smoothly raise the deck to its optimal sliding angle -> ensuring all materials slip effortlessly into the receiving hopper without manual shaking.
SJG Heavy-Duty Guide Rail Lifter with Tilting Deck Framing: Weak platform frames warp over years of forklift loading and high-angle twisting. Our Guide Rail Lifter with Tilting Deck is constructed with a thick-walled 120x60x4mm rectangular steel tube subframe topped with a 3mm carbon steel plate -> maintaining flat rigidity under heavy rolling loads and preventing framework twisting during off-center tilts.
Delixi Industrial Electrical Control System: Dusty bulk discharge sites can cause fine particles to penetrate electrical cabinets, shorting out relays. We house all controls in a dust-sealed Delixi electrical cabinet featuring integrated copper ground lines and analog pressure gauges -> ensuring safe, isolated signal routing and offering operators real-time visibility of system pressure.
Custom Wuxi Fangli Low-Temperature Geared Motors: Low-grade electric motors struggle to start in freezing climates, often burning windings due to high starting resistance. We equip the 3-Ton Heavy Duty Tilter with Wuxi Fangli low-temperature motors matched with dual liquid level gauges -> delivering high-starting torque in cold weather while allowing quick visual oil checks.
Double-Span Lifting Geometry (2-Cylinder 4-Rail): Traditional single-rail lifts lack lateral support, shaking violently when bulk materials slide off. Our Double-Span Scissor Lift Table variant utilizes a rigid 2-cylinder 4-rail mechanical alignment -> ensuring the platform carriage remains locked in place, absorbing the shifting center of gravity during discharge.
Outdoor Industrial Waste Gas & Carbon Adsorber Plants (Environmental Engineering): In heavy environmental machinery fabrication facilities, bulk plastic pellets or carbon granules must be loaded into elevated 3-story purification silos. Operating outdoors in freezing climates, our Hydraulic Lift and Tilt Platform reliably lifts the 3-ton material containers up 6.3 meters. Its thermostatic hydraulic heater prevents oil freeze-ups, while the precise 60-degree tilt automatically discharges the carbon smoothly into the hopper without manual labor.
High-Throughput Metallurgical Stamping & Scrap Sorting Yards (Recycling & Steel): Metal stamping lines produce tons of heavy circular steel punch scraps that collect in heavy steel bins. Utilizing the SJG Lift and Tilt Table allows forklifts to drop these scrap bins at ground level. The lift elevates the load and tilts the platform, sliding the dense metal scrap directly into outdoor scrap truck beds, shielding the guide rails from aggressive off-center impact forces.
Agricultural Grain Feed & Silo Processing Facilities (Bulk Storage): Feed processing plants handle giant bulk bins of grain that must be elevated to high-level mixing silos. Utilizing this Bulk Material Unloading Lift ensures that loose grains are elevated via H-beam columns and tilted gently at a precise angle, allowing gravity to feed the silo intake with zero product spillage or dust explosion hazards.
Sub-Zero Municipal Waste & Sludge Dewatering Stations (Municipal Water): In municipal dewatering sites situated in cold regions, heavy sludge hoppers must be elevated and discharged into drying beds. Utilizing our Low-Temperature Hydraulic Lift with waterproof electrical boxes ensures continuous operations under splashing water and freezing temperatures, dumping wet sludge safely without exposing workers to toxic slip hazards.
Industrial Ceramics & Mineral Powder Blending Mills (Powder Manufacturing): Powder factories blend heavy bulk raw clay and silica powders that must be fed into high-level ball mills. Our custom Guide Rail Lifter with Tilting Deck rises up 6.3 meters, locks onto the mill chute, and tilts the powder bin to a steep angle, allowing abrasive raw materials to exit cleanly without generating hazardous airborne powder clouds.
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.
