Both tooling offers justify suitability with the motor housing's mass. Extended fingers, adapter and hose fittings are also coming along. What needs comparing before I buy?
Request the complete loaded assembly, not just a heavier total. Its centre of gravity and inertia matter with the proposed grip position, orientations and motion.
Correct. Have each supplier identify the arrangement it is offering and assess it against the applicable robot limits. A parts list is useful purchasing information, but it does not establish the installed load geometry.
Include the assembly revision in the purchase scope. Maintenance will need to know which fingers and adapter the assessment covers. An alternative spare may fit mechanically without preserving the assessed load or grip arrangement.
Jasper, that also makes a later supplier substitution visible. Lucy should not have to guess whether a changed finger length is covered by the old assessment.
Keep that responsibility open on the comparison sheet. The hardware price cannot quietly become a complete engineering offer because all the component names are present. Someone must own checking the offered assembly for your task.
