Pre-purchase check
overhead crane attachment manufacturer
This page is a compatibility check before you accept an overhead crane attachment manufacturer line. It is not a quotation and not an inspection report.
Match the hoist and below-the-hook device to the crane before the model name
Carrier attributes come first: crane rated capacity with metric tons or short tons named, hoist or trolley type, hook or pin dimensions, and the duty classification of the crane—not the catalog nickname of a grab, magnet, C-hook, or load cell. A device labeled “7.5 tons” is not interchangeable with a crane whose nameplate uses short tons, or with a 7.5 metric-ton crane whose hook block is already at that rating.
Carrier
Crane capacity named as metric tons or short tons, girder type, and hoist duty class before any attachment model
Ratings
Below-the-hook working load versus crane and hoist ratings, same unit on both sides
Interface
Hook size, shackle or pin diameters in mm, power for magnets, and load-cell capacity
A substituted or “equivalent” part is accepted only after the supplier states the interface dimensions, the working load in the same named unit (metric tons or short tons) as the crane, and who signed that match. Hydraulic flow in L/min and pressure in bar apply when the attachment is a powered grab or rotator; they do not replace the crane capacity check. Bumper, limit, and anti-collision devices are runway interfaces; they still need the crane mass and speed, not a generic catalog number.
Third-party hoist or attachment pages show how the category is specified. They are not our stock, our production, or an authorization. Open inquiry options or the procurement checklist after the interface list is filled.
