Conduit Bending Tools

Conduit Bending Tools Points : conduit bending tools, hickeys, bending racks, pressure benders, roller benders, definition There are four types of conduits bending tools. They are:
(a) Hickeys
(b) Bending racks
(c) Pressure benders
(d) Roller benders (a) Hickey It is a practical tool that is used so commonly by the electrician for bending the conduits without spoiling the true round shape of the conduit. It is hand bender based upon the principle of levers. It consists of a slot into which the conduit to be bent is engaged and has a theaded end with which is attached a handle by means of a pipe coupling. Fig. (a) shows a Lakin hickey, while Fig. (b) shows the hickey with a handle. The size of the Lakin hickey depends upon the size of the conduit to be bent, but there is another type of hickey which has a movable jaw and when the operator pulls the handle, it automatically grips the conduit and prevents the tool from slipping.

(b) Bending Racks It has an arrangement of ‘A’ shape made from wood as shown in Fig. in such an arrangement on end of the conduit is fixed and a force is applied to the other end of the conduit. The leverage of the bending conduit can be changed.

(c) Pressure benders For pressure bending of the conduits, the conduct is laid as a beam and the pressure is applied at the centre. Such a bender is shown in Fig.

(d) Roller benders There are many types of roller benders. Fig. shows an arrangement of roller bending in which system, a roller is used at the top and bottom of the conduit.
