MV-LC0010 Load Pin for 55 mm Joint Replacement, up to 15 t

METRAVON MV-LC0010 is a load pin with a diameter-55 reference, a 200 mm longitudinal outline and a technical maximum of 15 t. For an existing joint, those dimensions are only the start of the replacement check. The contact locations, retaining notch, force orientation and controller interface must also match the approved supplied version. A pin that enters the old bore is not yet a verified replacement.

Document the old joint before removing the sensing pin

Keep the old mechanical drawing, fitted direction, bush and spacer positions, connection record and instrument settings with the replacement enquiry. Inspect the bore and contact surfaces during a safely supported shutdown. The actual pin reaction needs to be established from the mechanism, rather than assumed equal to a lifted or carried mass. If the old failure involved wear, impact or changing zero, record those conditions so that replacement does not leave the original mechanical cause in service.

Compare the 55 mm load pin contacts and retaining detail

The outline shows a 200 mm longitudinal reference, two 12 mm relieved sections and a 78 mm central reference. The diameter-55 lands carry negative tolerances of -0.03 and -0.08 mm. An end notch is shown with separate local dimensions. Map the old loaded member, both supports and axial retention onto those datums. Do not move a keeper or bush simply to use an old fastener location if that changes contact with the sensing regions or blocks the cable outlet.

Release the output version before restoring power

For the bridge configuration, the reference is 1.0 +/-0.015 mV/V with 10-12 V DC excitation. A separately listed 4-20 mA route uses a 24 V DC reference, and CANopen options require their own controller and cable documentation. Check the actual offered channel before reusing a connection. The reference bridge colour list and circuit disagree on signal polarity, so colour matching is not an adequate wiring method. Require delivered terminal functions and verify the loaded response under controlled conditions.

Re-establish scaling through the installed force path

Compare independent agreed reactions with the indication after the pin, keeper, bushes and cable are in their final positions. Record repeated loads, unloading return and any important mechanism positions. The 0.5% FS precision entry and separate 0.5% FS per 10 deg C temperature effect must be considered at the useful working loads. Reusing the old display span without a loading check can conceal a changed mechanical arrangement or output scale. Agree how the reaction is converted if the display reports another quantity.

Keep replacement approval separate from safety approval

Specify material, the completed IP67 cable arrangement and the actual pin temperature against the -40 to +85 deg C operating interval. Do not use the sensor 200% FS safe-load entry as a machine test target. If the pin participates in protective monitoring, require the selected channel architecture, controller behaviour and system validation records. The CANopen Safety option reference does not by itself approve the complete protective function or establish a certified safety level.

The MV-LC0008 short-joint arrangement has a 98 mm reference rather than this 200 mm outline. Use that comparison to identify a different installation requirement, not to establish a direct substitute.

Request MV-LC0010 with the old pin and joint drawings, failure observations, reaction loads, retained controller specification and a proposed loaded verification method.
