Hi RB, I have to securely tie the both ends of a 10mm rope; in order to make it like a chain (elevators). If the rope is 10mm; then what should be the size of the bulldog clip

If the rope is 10mm the bulldog will be 10mm. If its on a Elevator I hope its the governor rope and nothing else!

Hi HARIDAS.P.V, Well, if you are lifting with a 10mm rope you want to make sure whatever you are lifting is within the Safe working limit of the rope. You actually want the load to be within the safe working limit of the weakest part in the lifting system. What are you lifting and how are you lifting it, using a crane, hoist, pulley system, is rope the most practical way or is it steel rope? It sounds like a through risk assessment and safe system is needed for this task, possibly a hazop and still more information is required for this forum.

Sir, you are almost reaching to my point. It is exactly a governor rope. My only concern is both ends of the governor rope is to be secured thoroughly. In this case can I go for a 10mm bulldog or 12 mm bulldog clip is my concern

HARIDAS there should be a link arm at the side of the lift where the governor rope fits, you should have at least 3 bulldog clips at each end of the rope and the clips need to be put on so the dead end of the rope gets compressed when tightening up the bulldog. I am surprised the bulldogs where not supplied with the rope, in my opinion if its a 10mm rope you will need 10mm bulldogs but if in doubt contact the rope supplier, hope that helps.

Haridas Use only 10mm wire rope grips for 10mm diameter wire rope. Do not use larger grips as they may not provide sufficient friction to safely terminate the wire rope. Also with a larger than specified wire rope grip the securing nuts may become bottomed out before the correct torque values can be applied to safely terminate the wire rope. Do not try to force smaller diameter grips on to the wire or you will risk damage and subsequent weakening of both the wire rope grip and the body of the wire rope. If you want to read some very interesting and really scary stuff about wire rope grips then get a hold of this document: Wire Rope Grip Terminations (Research Report) Published by HSE Books (Jun 1996) ISBN-10: 0717611329. You will never look at wire rope grips in the same light again!!

Eddie that research report is "out of print" so not available. Shame I would have liked to have read that.

This is a specialist area and if you have doubt as to sizes to use etc. I advise that you get proper advice ['proper' advice does and can come from this site - but U know what I mean]; as if a clip slips?

With respect Bob I installed, modernised, serviced and fixed lifts/elevators for over 20 years, I would never give advice on a subject unless I was sure of what I was saying.
