Man in suit lifting equipment (4)

I believe the answer is:

jack

I'm a little stuck... Click here to teach me more about this clue!

'equipment' is the definition.
(I know that jack is a type of game equipment)

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for jack that I've seen before include "Knave (cards)" , "Lifting device - flag - boy's name - card - fish" , "-- Sprat; -- Horner" , "car tool" , "Car lifter" .)

I've seen this clue in The Independent and The Telegraph.
