This analogy is similar to load drift. If you stop your crane but the hoist continues to travel in either direction, there is a problem. The issue could be with the mechanical load brake, the holding [...]
Two key factors influence the “toughness” of overhead crane wheels: The hardness of the raw material used to make the wheels—such as alloys, low-carbon steel or medium-carbon steel and the heat [...]
Operational and load tests are critical for crane safety For the safety and productivity of your employees and workplace, it’s of critical importance to know that new or newly repaired or modernized[...]
When overhead cranes break down, so does productivity. And if you’ve been there, you know how costly lost production time can be. These five practices – from inspections to crane upgrades – can [...]
Workstation Jib Cranes offers easy, ergonomic lifting and transfer of repetitive loads. These small, nimble cranes are faster than motorized jibs and are very affordable. The workstation jibs can be p[...]
Bridge cranes cover rectangular work areas, while monorail systems can be used to move loads along a linear path, cover various work area shapes, or to link work areas together. Work station bridge cr[...]
Maintenance of Mobile Cranes Proper mobile crane maintenance must be given the highest priority. Cranes are machines that feature a hoist chain and sheaves used to move load vertically and horizontall[...]
First, make sure all travel limit switches are functioning properly. Pay particularly close attention to the hoist upper travel limit switch. Always check to make sure the wire rope is not kinked, fra[...]
Plugging poses the greatest risk with contactor-controlled cranes. The practice can cause severe load swings for contactor-controlled cranes, plus it can wear out contactors prematurely and create fla[...]
Although crane design classes have different designations in different design standards, one thing remains constant: each crane and hoist has an intended Design Life, which determines the amount of wo[...]
