Maple Helps Hiab Simplify Their Crane Operation
Hiab, a leading provider of load handling equipment, is using Maple to design new ways to lessen the burden on crane operators and maintain safe and precise machine operation. Hiab selected Maple because of its ability to process complex matrix manipulations and easily export computations to Hiab’s existing simulation software. Because Maple efficiently optimizes complex calculations, Hiab’s crane simulations run faster than ever before.
Cranes are large machines used to lift and relocate heavy payloads. Due to safety concerns, as well as potential damage to the payload or property, the well-trained operators must ensure precise movements of the crane. Often this requires performing multiple tasks simultaneously. Hiab, a leading provider of load handling equipment, is designing new ways to unburden the crane operator of some tasks while maintaining the safe and precise operation of the machine.
On a crane, the boom sections are extended and retracted by hydraulic cylinders. The operator controls the action in which hydraulic fluid is transmitted under high pressure into the cylinder. The hydraulic cylinders apply a force to the crane elements that control joint motions. Within the cab o...
On a crane, the boom sections are extended and retracted by hydraulic cylinders. The operator controls the action in which hydraulic fluid is transmitted under high pressure into the cylinder. The hydraulic cylinders apply a force to the crane elements that control joint motions. Within the cab of the crane, the operator controls each cylinder separately in order to move the tip of the crane to its desired location. The operator’s joystick movement directly controls the cylinder force and the velocity of joint rotation. The control method is very complicated and Dr. Morales is working on enhanced control algorithms to simplify the operation of the cylinders; controlling the individual cylinders with an end-effector (gripper).

Industry 4.0 and the Power of the Digital Twin
The world of industrial automation is undergoing a major transformation to the Next Industrial Revolution, or Industry 4.0. Manufacturers can no longer afford the “build it and tweak it” approach that has long characterized many design projects. Instead, they must take a more systems-design approach by implementing rigorous systems-design processes that accommodate the complexities of developing multi-disciplinary systems. High-fidelity virtual prototypes, or Digital Twins, are at the core of this development process. Read this whitepaper to learn how early adopters are already benefiting from the power of the Digital Twin as part of their Industry 4.0 strategy.
