The new PipeMaster™ MBC Series Pipe Haul-Offs from Conair offer durable, powerful pulling solutions for PVC and polyolefin pipe extrusion lines, with six models sized to handle pipe from 2.5 inches (63 mm) to 24.9 inches (630 mm) in diameter. They provide pulling torques ranging from 1,500 to 12,500 lbs. (7,000 to 56,000 N), respectively.
Each of the six MBC Series haul-off models feature motorized, direct-vector drives for smooth, consistent power delivery and pulling speed. Once extruded pipe enters the haul-off on a guide roller, pulling power is delivered through 59.1 inch (1500 mm) cleated belts that maintain controlled contact, without slippage or chatter marks on with the extruded pipe. The number of drive belts on the MBC Series models (two, three, four, six or eight) increases with the diameter of the pipe to uniformly distribute pulling power and maintain even, distortion-free pressure on the pipe circumference. Clamping force is evenly applied from above and below, with motors used to position the lower belts and pneumatics supplying proper positioning and positive pressure from above.
All MBC Series Haul-offs synchronize automatically with extruder screw speed controls and gravimetric material dosing systems to ensure stable production and consistent pipe unit weights. Speeds are adjustable depending on pipe size, ranging from 0.66 – 82 ft/minute. Haul-off controls are managed using an eye-level touchscreen HMI that provides straightforward access to speed control, alarms, and stored recipes, while maintaining communications with extruders, measurement systems, cutters, and other key equipment. Full equipment guarding for personnel protection is also standard.
According to Conair Vice President, Extrusion Ernie Preiato, the new MBC haul-offs “bring together rugged reliability, cost-efficient performance, and simple, well-engineered controls – all part of a larger PipeMaster line that is backed by Conair global service and support. The size range and versatility of MBC Series haul-offs makes it easy for pipe producers to ‘right-size’ pulling capacity. Their precision performance helps maintain minimum wall thicknesses, essential to meeting pipe tolerances and strength requirements, and avoid excessive material usage, which could affect their profitability.”
