The IDS-808-40K-1 40,000 lb × 10 lb industrial crane scale is a self-contained hanging weighing system for very heavy suspended loads where a floor platform is impractical. MNM lists a 40,000 lb capacity, 10 lb accuracy/increment, rechargeable battery, AC adapter, remote control, five-digit LCD/LED display and a 90 kg scale weight.
Published IDS-808-40K-1 Specifications
Capacity — 40,000 lb. Published accuracy/increment — 10 lb. Display — five-digit LCD/LED. Power — 6 V / 3.2 Ah rechargeable battery. Charger — AC 110 V input. Remote control — included. Tare range — 100% full scale. Zero range — 4% full scale. Surrounding temperature — -5°F to 140°F. Operating temperature — 15°F to 105°F. Product weight — 90 kg. Warranty — one-year limited warranty. The listing also shows “Accuracy: III,” but does not state NTEP certification, so that line should not be treated by itself as proof of legal-for-trade status.
What 40,000 lb × 10 lb Means
Ten-pound displayed steps provide 4,000 divisions across a 40,000 lb range. That is appropriate for heavy industrial weighing where changes of tens or hundreds of pounds matter more than single-pound variation. As with every scale, displayed resolution is not the same as complete uncertainty; loading motion, temperature, calibration, hanging geometry and dynamic force all influence the quality of a result.
Why the Rechargeable Battery and Remote Matter
A crane scale is often several feet above the operator and may move between bays or work areas. Battery power avoids a live power cord near a moving suspended system, while the remote can reduce the need to approach the scale body for normal commands. Battery condition should be checked before critical work; an extremely heavy scale hanging overhead is not a convenient place to troubleshoot power problems after a load is already suspended.
Typical Industrial Uses
Potential applications include fabrication shops, foundries, warehouses, steel handling, machinery movement, shipping and receiving, heavy component weighing, production staging and controlled load tests where an appropriate overhead lifting system already exists. The crane scale measures suspended weight; it does not replace the rated crane, hoist, shackles, hooks, slings or site lifting procedure.
The 90 kg Scale Weight Is a Real Planning Factor
MNM lists the unit at 90 kg, roughly 198 lb. That self-weight affects storage, installation, handling, headroom and the total load carried by the crane system. Facilities should plan how the scale itself will be attached, removed and serviced without creating an uncontrolled manual-handling problem.
Important Note About the Safe-Load Wording
The product page lists “Maximum safe load: 125% F.S.” and separately “Overload: 100% F.S.” That wording is not clear enough to use as an operating instruction. Treat 40,000 lb as the rated weighing capacity and do not interpret the 125% line as permission to intentionally lift above capacity. For overload, rigging and structural limits, follow the exact product manual and the facility's qualified lifting/engineering requirements.
Calibration and Daily Checks
Before use, check the display, battery, zero condition, visible hardware condition and a known reference when your procedure requires it. Formal calibration at 40,000 lb capacity needs appropriate reference equipment and should not be improvised from an unverified suspended load. After service, overload, impact or questionable readings, remove the scale from critical measurement use until it has been inspected and verified.
FAQ
What is the capacity? 40,000 lb. What is the stated increment? 10 lb. Does it include a remote? Yes. What battery is listed? 6 V / 3.2 Ah rechargeable. What charger input is listed? AC 110 V. How heavy is the scale itself? MNM lists 90 kg. Is it legal for trade? The page does not state NTEP certification, so confirm certification requirements separately. Can I intentionally weigh 50,000 lb because the page mentions 125% full scale? No; do not interpret that ambiguous line as an operating allowance beyond the 40,000 lb rated capacity.
