300KGS / 600 LBS Electronic heavy Duty Hanging Crane

Upgrading to a Heavy Duty 300 KG Digital Mini Crane / Hanging Scale gives you a much higher structural load tolerance compared to the 200 kg version. These are typically built with thicker metal casings or premium ABS, designed specifically for rigorous industrial, agricultural, or hunting workloads.

The two most common form factors on the market are the Weiheng WH-C300 style (rugged ABS body) and the Cast Aluminum Industrial style (all-metal casing).

Technical Specifications (300 KG Class)

1. Weight Limits & Accuracy

• Maximum Capacity: 300 kg (approx. 660 lbs).

• Minimum Weighing Capacity: Starts between 0.2 kg to 10 kg depending on the specific sensor calibration.

• Precision / Graduation: Divides increments down to 0.05 kg (50g) or 0.1 kg (100g).

• Measurement Units: Multi-unit conversion allowing you to switch between Kilograms (kg), Pounds (lb), and sometimes Newtons (N) or Jin.

2. Heavy-Duty Materials & Mechanical Build

• Housing Options:

  • Option A: Industrial-grade, high-strength ABS engineering plastic.

  • Option B: Ultra-rugged die-cast aluminum alloy casing (finished with a heavy anti-rust coating, usually in high-visibility orange, red, or black).

• Hardware Setup: Equipped with a thickened, heavy-duty stainless steel top shackle (fixed) and a detachable stainless steel bottom S-hook.

• Internal Core: Built using a dedicated alloy steel S-type strain gauge load cell with built-in overload protection to prevent deformation.

• Weight of Tool: Surprisingly light given its strength, weighing between 460g to 1.2 kg.

3. Display Interface & Controls

• Screen Display: High-contrast 23mm LCD or LED digital display screen. It includes a bright white or blue backlight, allowing you to easily read weights from over 10 meters away.

• Interface Controls (3 Keypad Layout):

  • TARE: Zeros out the scale instantly (perfect for disregarding the weight of shackles, ropes, chains, or heavy industrial buckets).

  • HOLD: Manually or automatically locks the weight reading on the screen once it stabilizes. This means you can drop the heavy item safely and still read the final weight measurement.

  • UNIT / MODE: Alternates between kg, lbs, or N.

4. Smart System Protection

• Overload Alert: Immediately displays an error code (oL or EE) if a load exceeding 300 kg is detected, protecting the load cell from bending.

• Low Battery Alert: Visual warning prompt (Lo) on the display before the screen completely blanks out.

• Smart Auto-Off: Automatically shuts off the bright backlight after 5 seconds of absolute stillness and powers down the primary electronics after a few minutes of inactivity to optimize power.

5. Power Layout

• Battery Requirements: Runs on 2 x AAA batteries or 3 x AAA batteries depending on the casing type.
