3. The system of claim 1, wherein the performance simulator is further configured to:
analyze, if the estimated total effective grade exceeds the threshold level, the collected data to determine a potential cause of inconsistency between the collected performance data and the design performance data; and
generate a report that summarizes the potential cause of the inconsistency and provides recommendations for resolving the potential cause of the inconsistency.
4. The system of claim 3, wherein the performance simulator is further configured to:
estimate an actual remaining lifespan associated with one or more of the components of the machine based on a current payload level;
generate a simulated remaining lifespan associated with one or more of the components of the machine based on the established payload limit; and
wherein the report further summarizes a difference between the actual remaining lifespan and the simulated remaining lifespan.

selecting a first payload level for the machine;
simulating a speed of the machine based on the first payload level;
determining whether the simulated speed is within a target speed threshold; and
selecting, if the simulated speed is not within a target speed threshold, a second payload level for the machine and simulating the speed of the machine based on the second payload level;
wherein establishing the payload limit for the machine includes establishing, if the simulated speed is within a target speed threshold, the payload limit for the machine as the first payload level.
6. The system of claim 5, further including:
generating a payload notification indicative of the payload limit for the machine; and
providing the payload notification to a payload subscriber.
7. The system of claim 1, wherein the performance simulator includes the torque estimator.

All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A hydraulic accumulator, especially a pulsation damper, comprising a metal bellows (19) which on at least one bellows end (31) has an end body (35), said end body being movable along the wall of the housing (1) during the expansion and compression of the bellows (19), between the end body and the housing (1) there being a guide means (47) which on at least one peripheral region of the end body (35) on its outer periphery forms first annular sections (51) which have a radial distance from the wall of the housing (1) and which are separated from one another by second annular sections (53) which project radially beyond the first annular sections (51) and which are distributed on the outer periphery, the end body (35) being axially lengthened by a peripheral sleeve part (63) which extends in the direction to the immovable bellows end (29), and the end of the sleeve part (63) adjoining a housing-mounted retaining ring part (25) as a stop body when the bellows (19) is compressed, wherein the bellows (19) on the bellows end (29) opposite the movable end body (35) is fixed on the housing-mounted retaining ring (25) which the end of the sleeve part (63) strikes, and that the guide means (47) has an annular body which with one annular part (49) which forms the first annular sections (51) engages on the end body (35) a peripheral annular groove (45) which is located axially offset on the end body (35) away from the immovable bellows end (29) in the direction which increases the distance to the retaining ring (25).
2. The hydraulic accumulator according to claim 1, wherein the sleeve part (63) extends over a distance which exceeds the axial length of the compressed bellows (19).
3. The hydraulic accumulator according to claim 1, wherein in the sleeve part (63) there is a second annular groove (67) for the annular part (49) of another annular body (47) in the position which is axially offset toward the first annular groove (45).
4. The hydraulic accumulator according to claim 1, wherein the respective annular body (47) is formed from a plastic material with good sliding properties.
5. The hydraulic accumulator according to claim 1, wherein on the respective annular body (47) the second annular sections (53) are axially bordered by surfaces which are shoulderless continuations of the radial planes of the annular part (49) which is to be accommodated in the pertinent annular groove (45, 67).
