Increased production, faster operating speeds, better controls, or automation and those are just the tip of the ice-burg of what you can gain when you decide to modernize or upgrade your crane.
On top of this modernizing your crane can be a perfect solution for if your reliability has deteriorated to the point where you now are experiencing unscheduled shut-downs which in turn increase your production costs. If it is an older model of crane many of the parts now may be obsolete which will result in a high cost for spare parts and a long lead times. Your inspections also may show excessive wear or even non-compliance with current safety standards and practices. All of these are reasons as to why someone may choose to upgrade their crane or other lifting device.
