ROPE CAPEL
Are widely used for connecting the winding rope to the suspension gear. The use of rope Capel is a basic requirement of safety in winding.
D-LINK
These are used to attach any two components of cage suspension gear & to adjust the height of cage suspension gear. The diameter of the link rod should be 1.5 times the rope’s dia. & should not be any join in the link.

It is always placed just below the rope Capel.
TRIANGULAR PLATE
Triangular plate is also known as load distributing plates. Its function is to distribute the load of the cage, hence it is known as load distributing plate.
it consist of one hole at the top which is connected to the safety hook & at the lower end it consists of three holes which are connected to the cage through bridle chains.
BRIDLE CHAINS
These are used to attach the cage with the triangular plate, For a small cage only four chains are used at the four corners of the cage while in case of large cage total six chains are used.
