01Overview
Hangs between the crane hook and the load, giving an instant digital weight reading as the load lifts clear. Wireless remote display models are available so the operator can read the weight from the crane cab rather than the load itself.
02How it works
A tension load cell between hook and load
A crane scale hangs directly between the crane's hook and the rigging attached to the load, using a tension-type load cell — measuring pulling force rather than compression — since that's the physical arrangement a suspended load naturally puts it in. As the load lifts clear of the ground, the full weight transfers through the scale, and the digital display shows the reading instantly, before the load has even finished rising.
Wireless remote display solves a basic visibility problem
The scale's own display sits up at the hook, often well out of the crane operator's line of sight from the cab, especially on a tall gantry or tower crane. A wireless remote handheld display receives the same reading over a radio link, so the operator can read the load weight from the cab without craning their neck or relying on someone else to call out the number.
The overload alarm is a safety interlock, not just a warning light
As the reading approaches or exceeds the crane's or the rigging's rated capacity, the overload alarm alerts the operator before the lift proceeds further — catching a miscalculated or misidentified load weight before it becomes a rigging failure or a crane capacity violation, which is one of the more common causes of serious lifting accidents.
03Manufacturing & build quality
The tension load cell at the core of the scale is machined and strain-gauge-fitted to handle the specific loading geometry of a suspended hook — a different mechanical arrangement than the compression load cells used under a platform scale — and is housed in a rugged enclosure designed to withstand the knocks and rigging-chain contact that come with routine lifting use. The digital LED display is chosen and tested for readability in direct outdoor sunlight, a real requirement for equipment used on open construction sites and yards. Wireless remote display models are paired and range-tested during manufacturing, and the rechargeable battery system is validated for its rated runtime (typically 40-plus hours) before the complete unit — load cell, display, and battery — is calibrated and functionally tested under load before dispatch.
04Problems it solves
No weight feedback risking crane or rigging overload
Lifting a load without knowing its actual weight means relying on estimation or paperwork that may not reflect the load's true mass — a crane scale gives a real, instant reading at the point of lift, removing that guesswork.
Operator unable to see the on-hook display
Without a wireless remote, the operator has no direct view of the weight reading from the cab, forcing either a stop-and-check routine or reliance on a second person relaying the number.
No automatic warning before an overload occurs
Without a built-in overload alarm, an operator has no automated safeguard against exceeding rated capacity — the alarm catches that before it becomes a structural or rigging failure.
Guesswork in load planning
Planning a multi-lift job without accurate weight data for each load makes it hard to sequence lifts correctly against crane capacity at different boom angles and radii — accurate on-hook weighing removes that uncertainty.
05Why it matters
Crane overload is one of the most common root causes of serious lifting accidents, and it's an entirely preventable one if the actual weight of the load is known before and during the lift rather than assumed. A crane scale turns that critical piece of information from an estimate into a measurement, in real time, at the exact point in the process where it matters most — and the wireless remote display means that information actually reaches the person making the lift decision, not just a screen hanging at the hook where no one can see it.

09Frequently asked
What capacity should we choose?
Match it to your heaviest routinely lifted load, with margin — crane scales in this range span roughly 500kg to 50 tonnes, so specify based on your actual load profile rather than your crane's maximum rated capacity alone.
How far does the wireless remote display work from?
Range depends on the specific model and site conditions (obstructions, other RF interference), but the wireless link is designed to comfortably cover typical crane cab-to-hook distances on the sites this equipment is used on.
How long does the battery actually last between charges?
Typical runtime is 40-plus hours on a full charge under normal use, though actual runtime depends on display brightness settings and how frequently the scale is actively weighing versus idle.
Can it be used outdoors in all weather?
Yes, it's built for outdoor lifting environments — direct sunlight readability on the LED display and a rugged housing are both part of the standard design for this reason.
Does a crane scale need its own calibration/certification for lifting equipment compliance?
Yes — as load-measuring equipment used in lifting operations, it should be calibrated and, where applicable, certified per your local lifting equipment regulations on a periodic schedule, separate from any certification the crane itself carries.
