Ask for the complete proposed assembly, with total mass and load geometry including the held housing at its intended grip position. The supplier should assess that configuration for your required movement, not just compare the housing weight with a headline capacity.
15分One quote lists the adapter as customer supplied. No drawing reference. That makes its claimed suitability fairly ambitious.
18分Does your workshop already have the adapter they mean, Daniel? Customer supplied could identify a real component, but the quotation needs to say which one.
13分And who selected the finger length? Is it tied to a measured access requirement?
14分Emma, no adapter selected. Lin, length came from reaching past the nest wall. The supplier has the wall height but not the complete loading route.
10分Get that missing route into the request too, including release and withdrawal, so the tool choice is reviewed against what it actually has to do. Loading the part and getting the tool out are both part of the job.
22分Zara, yes, though I would not wait for a final route before asking them to identify the assembly assumptions. Daniel needs to know what their existing price actually buys.
4分Agreed. Send the scope questions now. I meant the complete movement must be part of the suitability decision, not that purchasing should sit quietly until everyone finishes drawing.
23分A separate option price for the adapter could be useful, provided responsibility for confirming the combined assembly stays explicit. Otherwise two suppliers can each deliver their own perfectly adequate half.
7分Is the housing orientation during transfer agreed?
16分Pickup and destination orientations are agreed. The intermediate route is not. I've sent both suppliers the same nest drawing and required endpoints.
14分Include the housing drawing and proposed grip depth with those endpoints. A picture of the nest alone will not tell them where the held load sits relative to their adapter.
20分Housing drawing supplied. Grip depth remains their proposal to justify, not a dimension I am going to guess for them.
8分Reasonable. Keep the two proposed depths visible in the comparison if they differ.
4分Daniel, do the quotes include the same fittings? A bare gripper drawing can make the shorter assembly look much more compact than the delivered tool.
15分No. One drawing has fittings, the other says pneumatic accessories excluded. Asked for the actual arrangement. Still no complete comparable offer.
4分Who from maintenance will review replacing those fingers and fittings once the assembly is defined? A workable transfer can still leave an awkward service job around the nest.
11分And ask each supplier to name what remains unassessed in its revised offer. An honest provisional price is usable; a complete-looking price assembled from different assumptions is a pain.
