Greenlee 881 Cam-Track Bender for 2-1/2 Inch, 3 Inch, and 4 Inch with Hydraulic Pump

Description

Satisfies strict National Electrical Code bend radius requirements on heavy commercial conduit up to four inches without pipe deformation. The Greenlee 881 Cam-Track Hydraulic Bender pairs a hydraulic ram with dedicated shoes to form thick pipe cleanly. It tackles massive runs, but assembling the heavy cam-track frame requires substantial setup time.

High-strength ductile iron forms the cam-track shoes and follow bars to prevent conduit wall flattening under extreme pressure. A 115-volt electric hydraulic power pump produces 10000 PSI operating pressure, drawing 15 full-load amps. The complete system with pump and shoes weighs 1100 lbs in its steel storage gang box, occupying a shop floor footprint of 60 inches long by 32 inches wide.

Key Features of Greenlee 881GXDE980

Industrial electrical contractors looking to buy Greenlee 881GXDE980 systems fabricate heavy commercial service entrances and utility substation runs. Commercial equipment pricing reflects the complete cam-track shoe assortment and high-pressure hydraulic pump.

• Cam-track shoe geometry eliminates conduit flattening across large bend angles.
• Hydraulic cylinder delivers 10000 PSI to bend four-inch rigid pipe with ease.
• Fast pin-locking frame design speeds up shoe size changes in prefabrication shops.
• Electric hydraulic pump features pendant control for precise operator sightlines.
• Bends 2.5-inch, 3-inch, 3.5-inch, and 4-inch EMT, IMC, and rigid steel conduit.
• Heavy-duty steel follow bars maintain pipe cross section integrity throughout arcs.
• Degree indicator pointer provides immediate bend angle references during the ram stroke.
• Wheeled steel job box stores all shoes, pump, and frame components securely.

Hydraulic Pressure Cylinder Load Curves

Pushing four-inch rigid steel conduit to a ninety-degree sweep requires 8800 PSI hydraulic line pressure. Ram travel takes approximately ninety seconds to complete a full ninety-degree sweep without hesitation. Under peak tonnage load, cylinder ram deflection holds within 0.004 inch along the frame guide track. Hydraulic fluid temperature inside the electric pump reservoir rises twenty-five degrees Fahrenheit after ten full sweeps. Conduit springback tests average two to three degrees across standard heavy-wall four-inch steel pipe bundles.

Prefab Yard Workflow Negative Filter

Operating this hydraulic table requires staging pipe supports to manage heavy four-inch conduit sticks safely. The hydraulic remote pendant triggers with zero delay through thick work gloves, though hoist equipment is required to load heavy shoes into place. Do not buy this cam-track system for small utility work or conduit smaller than 2.5 inches.

• Check hydraulic oil levels in the electric pump reservoir before every shift.
• Wipe grease and metal grit off the cam-track frame rails after use.
• Inspect high-pressure hydraulic hoses for outer jacket abrasion or fluid weepage.
