A crane scale hangs between the hook and the load to weigh it in the air, giving an accurate reading before a lift leaves the ground — essential for charge accounting, load verification and staying inside a crane’s rated capacity. Kranes supplies legal-for-trade and industrial crane scales across the capacity range, with wireless readouts, overload alarms and calibration. Tell us the maximum load, the accuracy you need and whether it must be trade-certified, and we return a quote with the right scale, shackles and calibration certificate. Replacement load cells, hooks and remotes are stocked for the units we supply.
A crane scale hangs in the rigging between the hook and the load, so it weighs a lift in the air before it ever leaves the ground. That single reading does several jobs: it confirms the load is inside the crane rated capacity, it provides an accurate weight for charge accounting and shipping, and it verifies a sling or spreader plan before the pick. Models range from compact dynamometer-style units to heavy industrial crane scales sized to match the largest hooks on site.
The right crane scale depends on how the weight will be used. Legal-for-trade (trade-certified) scales are required when the weight is the basis of a sale or invoice; industrial scales suit internal load checks, batching and safety verification. Wireless readouts put the number in the operator hand or a control room, overload alarms warn before a lift exceeds a limit, and tension load-link and crane-hook styles match different rigging. Kranes supplies the configuration, the shackles and the calibration to suit the task.
Specifying a scale comes down to the maximum load, the accuracy class you need and whether the reading must be trade-certified. From there Kranes returns a quote with the right capacity, the mounting style, the remote or display and a calibration certificate so the scale is ready to trust on day one. Because a crane scale lives in the load path, it is built and certified as rigging, not just an instrument — accuracy and a documented safe working load both matter.
A scale only stays accurate if it is maintained, so Kranes keeps replacement load cells, crane hooks, shackles, batteries and remotes for the units it supplies, and re-calibrates on schedule. That keeps the weight defensible for trade use and keeps the device safe in the rigging. Tell us the capacity, the accuracy and whether it must be legal-for-trade, and we respond with a quote, the calibration certificate and the parts to keep it reading true.
