Welded from 160 x 80 x 4mm rectangular structural tubing and 16mm base plate, this ASTM A36 structural steel cradle (certified GB Q235B equivalent with EN 10204 3.1 inspection certificates) eliminates angular frame twist under off-center die masses. The reinforced L-shaped cradle deck distributes point contact loads across circular rocker plates, preventing localized surface yield during continuous manufacturing rotations.
Twin strands of high-tensile 16A-2 duplex roller chain drive wrap the circular rocker perimeter, channeling rotary torque straight from the motor sprocket to the cradle chassis. This mechanical chain arrangement eliminates drive slip and gear tooth shear, delivering positive engagement that controls angular turnover velocities throughout the entire 90-degree turnover cycle.
Driven through an industrial 1.5 kW electric brake motor, the self-locking worm gear reducer eliminates mechanical freewheeling rollback during sudden power interruptions. High-ratio internal worm gearing provides permanent holding resistance at any intermediate tilt angle, locking heavy stamping dies motionless without hydraulic fluid contamination or line rupture risks on this 3-ton electric coil tilter.
Featuring pre-drilled rigging eyes and anchor points for concrete slab installation, this surface-mounted mold upender eliminates pit excavation costs and underground drainage maintenance. The standalone electrical enclosure incorporates Delixi contactors and dual travel limit switches, cutting power the instant the cradle reaches designated 0-degree horizontal or 90-degree vertical stop planes.
Engineered for automotive press shops and plastic tooling maintenance rooms. This surface-mounted mold upender reorients 3000 kg split mold halves from horizontal assembly orientations to vertical inspection planes without crane snatching. Anchored on a standard 200mm reinforced concrete plant floor, the chassis handles 20% eccentric tooling centerlines across ambient shop temperatures of -10°C to +45°C.
Deployed at metal processing plants and stamping line feed stations. The machine accepts steel coils with eye-horizontal axes via forklift tines, then rotates the payload 90 degrees to eye-vertical orientations for pallet strapping. The 4mm steel face plate resists edge abrasion from sheared sheet coils, while the 1500 x 1500mm bed accommodates varied coil outside diameters.
Serves electrical equipment manufacturing cells where wound motor stators and transformer laminations require vertical stacking followed by horizontal insertion. Operating on dry, level industrial factory slabs, the mechanical chain drive maintains precise 60-second cycle times, preventing impact shock to core windings during 90-degree material reorientation.
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.
