English term or phrase: crowd stall
Field trials of this system at several mines in Australia and at a large copper mine in
Arizona have successfully demonstrated the effectiveness of this particular feedback
tool. For example, the feedback system operating on a P&H 4100A in a coal mine
generated reductions in swing-during-dig ranging from 47 percent up to 69 percent
depending on the operator. In addition, a decrease in cycle time was experienced.
Based on the effectiveness of this system the Centre is actively commercialising this
tool and improving its capability to provide feedback on other unwanted operator
traits such as hoist and crowd stall. In addition, a parallel development of similar tools
for hydraulic excavators is proceeding.
A crowd control mechanism for a power shovel includes an extendible dipper handle having an extended position and a retracted position. A double acting hydraulic cylinder having a an extendible ram has one of the cylinder and the ram fixed to the dipper handle and the other of the cylinder and the ram is stationary relative to the dipper handle. At least one of the cylinder and the ram have at least one of a blind end port and a rod end port, and at least one of the cylinder and the ram have the other of the blind end port and the rod end port, wherein hydraulic fluid flowing into the cylinder through the blind end port urges the ram toward an extended position to extend the dipper handle, and hydraulic fluid flowing into the rod end port urges the ram toward a retracted position to retract the dipper handle. Hydraulic fluid flowing into and out of the cylinder is controlled by one or more pilot operated poppet valves. A spool valve is disposed in a pilot line controlling at least one of the pilot operated poppet valves, and the spool valve controls the flow of fluid into the pilot line to control the at least one pilot operated poppet valve as opposed to a spool valve directly controlling the flow of hydraulic fluid into and out of the cylinder.

Examples of motor stalls include:
Crowd Stall - Best practise is to keep the dipper moving up through the bank at all times, regulating the penetration of the dipper in the bank using the crowd/retract control.

parada/falha devido a sobrecarga


Explanation:
parada/falha devido a sobrecarga

The cross-bar (1.008) is curved to permit greater freedom of rotational movement for the crowd cylinder.

An arrangement of the crowd cylinder crank arm and linkage mechanism for giving freedom of movement for loading and tilting implements and buckets.

For optimal components protection, the crowding cylinder and the hydraulic hoses are housed in the nose of the boom while the reinforced underside provides protection for the engine and other vital components over rough terrain.
Common crawl
A crowd cylinder axle or crank arm (9.006) is offset from its rotational axis and includes a crowd cylinder pivot support 9.044 which is unobstructed in the direction of rotational operation of the cylinder about pivot point 9.010.

parada de penetração ...parada de empuxo


Explanation:
crowd stall => parada de penetração ...parada de empuxo

Crowding - Moving the dipper handle in or out in order to control the depth of cut or to position for dumping.
Swinging - Rotating the shovel between the dig site and dumping location. Propelling - Moving the shovel unit to different locations or dig positions.
Power shovel - Wikipedia
https://en.wikipedia.org › wiki › Power_shovel

Definition of crowding - Mindat.org
https://www.mindat.org › glossary › crowding
In power shovel nomenclature,
crowding is the thrusting of the dipper stick forward over the shipper shaft; retracting is the reverse of crowding. Ref: Carson, 1.

Digging force of electric rope shovel (ERS) has two components which are being crowd and bail pull forces. Crowd (penetration) force pushes the dipper into the bank whereas bail pull (breakout) force moves the dipper upwards to fill it. The resultant of the both forces is the digging force of the dipper of electric rope shovel. The optimization of crowd and hoist (bail) forces are extremely important; excessive crowd force application either stalls the equipment (heavy penetration) or jacks the boom backwards which is detrimental on both boom and boom suspension ropes (cables) due to heavy vibration caused. On the other hand, poor crowd force, shallow peneration, ends up with poor dipper fill.
