cr-2-30t Heavy Crane & Suspension Tension Load Cell 30 Ton

Forged 40CrNiMoA Alloy Steel, Quenched & Tempered. Engineered for cyclical tensile fatigue (>2,000,000 cycles) at full capacity of 30 Ton (30,000 kg).

• High-tensile forged alloy steel or stainless steel hardened to resist sudden snatch loads and tensile yield.
• Engineered for Heavy Tension Link / Shackle Load Cell ensuring high sensitivity and zero parasitic bending.
• Corrosion-resistant plating resists outdoor atmospheric oxidation in marine and oilfield sites.

Engineered with extreme safety margins: 200% FS safe overload and 450% Ultimate Overload ultimate breakload.

• Extreme breaking margin prevents catastrophic overhead drop hazards in crane hook and tensile testing applications.
• Sealed cavity (IP68 Heavy Water & Dust Sealed) prevents internal strain gauge degradation from dust, oil spray, and rain.
• High-strength forged clevis eyes designed to mate with standard Crosby-type safety lifting shackles.

• Bridge Impedance: Input 700 ± 15 Ω | Output 703 ± 5 Ω ensures precise mV transmission over long hoist cables.
• Wireless Handheld Terminal: Sends live hook weight wirelessly (433MHz / 2.4GHz) to a handheld driver terminal with thermal printer.
• Overhead Hoist Cut-Off Relays: Instantaneous SPDT relay trigger opens when load reaches 105% of SWL, stopping hoist motors.
• Peak-Hold Capture: Captures peak tensile force during destructive pull testing and dynamic wire rope proof-loading.

Heavy container handling and oil rig drill-pipe hoisting require shackle load cells with anti-corrosive marine plating to survive saline sea air and sulfur vapors.

Electromagnetic scrap crane hooks operate above intense foundry radiant heat. High-temperature heat-shield jackets prevent cable melt and signal drift.

Overhead gantry cranes lifting 30-ton steel rebar coils and limestone blocks subject sensors to severe snatch loading during rapid hoisting.
