Overload Factor - an overview | ScienceDirect Topics

In tower design, the basic load is increased by the use of an overload factor and the tower is designed to stresses approaching failures in yielding and buckling. In building and bridge design, the actual loads are used and the structure is designed to stresses at specified percentages of the failure in yielding or buckling.

Raptor XL900 Cone Crushers - focusonroadbuilding.com

An additional safety feature standard on all Raptor cones is the counterclockwise rotation crushing action that protects the machine if adjustment ring movement is excessive, or if the ring gear brake fails. Automation Raptor cone crushers use advanced overload sensing technology to detect crushing force overload. A simple alarm is activated.

SAFETY ELEMENTS FOR Mechanical Torque Limiters

within a few milliseconds of overload. Once again, an integral bearing allows for the load inertia to coast to a stop with-out further damage to the machine components or the torque limiter itself. The key advantage to this design is the quick reloading of the individual elements into the output flange with either

page 14). Crushers being operated beyond their permissible load range can result in serious damage. The LRS Load Reduction System, which works closely together with the CFS, has the task of preventing this. The "load monitor" in the software detects During the crushing process, various short-term or prolonged overload situations can arise.

Torque-limiting Couplings SafeSet, SmartSet and AutoSet

with small design changes. Design The SafeSet coupling design consists of a twin-walled pres-sure sleeve, which can be pressurized with oil up to 1 000 bar (14 500 psi), with the shear tube ensuring the system is com-pletely sealed. Larger SafeSet couplings have more than one shear tube which come in four standard sizes L 28, L 39, L 54 and L 63.


Our jaw crushers are of the single-toggle type and feature a deep, symmetrical crushing chamber, a large feed opening for its size, and an ideal nip angle that offers smooth material flow and high reduction efficiency. Jaw crushers are normally capable of a reduction ratio of 1:2 or 1:3. This ratio is affected by the feed

Industrial Solutions Gyratory crushers

The design of our gyratory crushers and jaw gyratory crushers is based on over one hundred years of experience gained by thyssenkrupp in the manufacture of these machines. Changing mining and processing techniques demand, besides new materials and design methods, continuous development of the products.


modularised design, where many components are utilised across the range, thus ensuring minimal stockholding of wear parts. A complete range of crushers ac-cepting feed sizes up to 1,000 mm (39 3/8") and throughputs of 700 TPH (772 STPH) nominally, ensure that we have a range of crushers to suit our customer's requirements.
