Rebar Steel Bundles
10 July, 2017
In a joint project alongside one of the top suppliers of hot rolled steel bar products in North America, 5 evo2 automatic crane hooks with load cell were mounted on a spreader beam at the company’s plant in order to load rebar steel bundles directly onto different “tricky” surfaces, such as train wagons, on a truck or just to simply move the bundles inside the warehouse.
evo2 Automatic Crane Hooks
Each steel bundle carries a tag with the total weight of every bundle. To compliment this interest in weight control all 5 safety hooks were equipped with load cells. With this feature linked to the eMAX remote control, the comparison of weight both from the tag and the load cell was confirmed in real time, therefore assuring the total weight displayed on the eMAX remote control matched the total on the tags of each rebar bundle. The load cell is fully integranted into the remote release hook and represents no increase in weight or dimensiones of the unit. Besides load control with the indication of total weight and of each individual hook, the load cell also informs of overload and/or unbalanced weight with different types of alarms.
With this upgrade, the company is able to track both the productivity and activity of each hook. The loading operation is very comfortable and quick: Chains with a master link are used to manually connect to the hook’s magnet. Once all master links are attached to the magnet, the crane operator remotely closes all 5 safety hooks hooks and lifts the rebar steel bundles.
Meanwhile, safety is enhanced as the automatic hooks help eliminate the risk of accidents when realeasing the load. Initially different operators had to get into the train wagon or jump onto the truck’s bed to help with the manual release. With the automatic release, this dangerous operation is no longer necessary and the bundles can be placed on any surface remotely.
