40 pipe when used with standard aluminum bending operation and maintenance procedures for the 880 shoes. The 880 bends up to 90˚ in one shot. Conduit Bender. • Standard aluminum shoes bend 1" - 2" GRC and schedule 40 pipe.
880 Hydraulic Bender Operating Instructions Setup 1. Place the ram (A) between the two halves of the 6. Position the pipe support so that the side of the pipe frame unit (F). support facing the conduit corresponds to the size of conduit to be bent.
7. Repeat steps 5 and 6 until the last bend is made. 8. Remove the conduit from the bend. RAM TRAVEL SCALE Centerline Bending Radii for the 880 Bender Rigid Shoe Size 1-1/4 1-1/2...

880 Hydraulic Bender Laying Out One-Shot 90˚ Bends 1. Measure the length of the required stub. See Figure 1. 2. Find the minimum stub length for that diameter of JUNCTION conduit on the Deduct and Minimum Stub Length Table. The stub you require must be equal to or lon- ger than the minimum stub length.
19-5/16 2. Determine the angle of the offset bends. 3. Calculate the center-to-center distance. See the Greenlee Offset Multiplier and Shrink Table. Note: If working toward an obstruction, calculate the amount of shrink. See Calculating “Shrink” in this manual.
880 Hydraulic Bender Laying Out a Segment Bend When a bend with a large radius is necessary, segment bending is required. Segment bending requires a series of small bends, or shots, spaced closely together. Use the formulas and tables that follow to mark the conduit.
