Industrial Crane Scales

Select a capacity at least 20-30% higher than the heaviest load you expect to lift to avoid overload; common capacities range from a few hundred kilograms to several tons. Verify the scale's rated capacity and safety factor against your lifting hardware and load chart

Choose a scale with resolution and accuracy that meet your tolerance needs — higher accuracy (smaller divisions) is required for billing or inventory control, while general-purpose lifting often accepts lower resolution. Check the specifications for readability (e.g., kg or lb increments), linearity error, and calibration options

Key features include a robust shackle or hook rated for your loads, a clear high-visibility display (often remote or wireless), durable housing with water and dust protection (IP rating), tare/zero functions, and connectivity options like Bluetooth or RS232 for logging. Confirm compatibility with your hoist rigging and any required data output formats

Look for ingress protection (IP) ratings for dust and water resistance, operating temperature range, overload protection or load limit alarms, and certification relevant to your jurisdiction (e.g., calibration, traceability, or industrial safety standards). These ensure reliable performance in shop, yard, or outdoor conditions

Perform routine inspections for wear on shackles and hooks before each use, and calibrate according to manufacturer guidance or regulatory requirements, typically annually or after any overload or repair. Keep components clean, avoid shock loading, store away from corrosive environments, and document calibration records

Confirm that the scale's top and bottom attachment points match your hoist, shackle, or lifting beam dimensions and load directions; verify swivel or non-swivel requirements and the scale's rated load axis. Also check clearance for the display and remote antenna placement if using wireless controls

Prices vary by capacity, accuracy, build quality, and features; budget models start under $50 for low-capacity consumer-style units, while higher-capacity, industrial-grade scales cost substantially more. Key cost drivers are maximum capacity, IP rating, certifications, and advanced connectivity or data-logging capabilities
