A Multicast XLSC360 is used to manufacture larger diameter pipe upto 3600mm diameter, here shown forming the spigot of the pipe.

Finished products are offborne from the Multicast machines and transported to a curing area where they are immediatelydemoulded.

CONCRETE PIPES AND MANHOLES

Hume’s new pipe and manhole manufactur-ing facility in Papakura south of Auckland isproof of their continuing commitment totheir founder’s philosophy. Housing threeHawkeyePedershaab Multicast Machines,this equipment brings the latest in vibrationmanufacturing technology to the Humesorganization. According to Mike Mac-Donald - General Manager of HumesPipeline Systems - HawkeyePedershaab’svibration technology has resulted in manybenefits for their organization. Manu -facturing output is higher and much morelabor efficient. The Multicast’s PLC processcontrol system results in excellent and con-sistent product tolerances with less relianceon operator skill, and their new vibrationmanufacturing process is more environmen-tally friendly, consuming 30% less energyand producing far less waste.Not only does HawkeyePedershaab’s vi -bra tion technology benefit Humes, it alsoprovides their customers with many advan-tages too. With the higher productioncapacity of their Multicast Machines,Humes can now manufacture up to tentimes more of a given pipe size per day ascompared to their previous machinery.Their ability to supply more pipes morequickly to the job site permits contractors tostep up their installation schedule and finishprojects in less time.

The vibration technology also made it pos-sible for Humes to offer several new prod-ucts to their customers. These products in -clude new jacking pipe options, several stylesof improved lined pipe, and a more versatileline of manhole products, including baseswith pre-benched flow channels.

Additionally, the switch to new manufactur -ing tooling presented an opportunity forHumes to review their products and toupdate them with the latest improvements.One advancement was to upgrade theirproduct joints for use with pre-lubricatedsealing gaskets, another benefit for con-tractors as it simplifies the process ofinstalling pipelines.

It’s all part of Hume’s continuing commit-ment to providing the best solutions for theircustomers. And the versatility of their newHawkeyePedershaab Multicast machineshelped to make it all possible.Hume’s new Papakura facility includes threeHawkeyePedershaab Multicast Machines.Two machines, a Model SCC 200 Multi -cast and a Model XL SCC 360 are used tocurrently manufacture DN 900 through DN2400 mm concrete pipe in 2.5 and 3.0meter lengths. Both machines are equippedwith central core vibration and a PLC sys-tem to control the filling and vibration

processes. In addition to regular reinforcedconcrete pipe, Humes also uses thesemachines to manufacture lined concretepipe and jacking pipe.

After the pipe is manufactured on the Multi -cast Machine, an overhead crane is used tooffbear the finished product from themachine. Securely held in the form’s outerjacket, the finished product is immediatelydemould ed in the curing area so that theexternal jacket can be reused for furtherproduction. To maximize the output rate oftheir Multi cast machines, Humes chose touse two external jackets for certain pipesizes. This permits the additional jacket tobe immediately set over the inner form coreat the Multicast station as the other jacket isbeing demoulded in the curing area. Thisoperating arrangement permits nearly con-tinuous production of pipe from Hume’sMulticast Machines.

A third Model SCV 250 Multicast Machineis used to manufacture a full range of man-hole products including riser sections, topcone sections and integrated base sections.A VB25 vibration table mounted to the pro-duction base of the Multicast Machine isused to densely compact the concrete. Thishydraulically operated vibration techniqueis well suited for manhole products, espe-

Humes Pipeline Systems, with eight manufacturing plants and twenty-two service centers, is New Zealand’s largest supplier of pipeline pro-ducts. Humes - today a division of Fletcher Building, an NZX & ASX listed company – was founded in 1923 by Walter Hume, the inventor ofthe spun pipe production methodback in 1910. Humes is a company built on the principle of being first to the market with new technologyand with manufacturing expertise to supply their customers with high quality, innovative products.

cially products with large horizontal sur-faces such as base sections.

Hume’s SCV 250 Multicast is set up for fullyautomatic production, except for the de -mould ing step. The concrete feeder isequipped with a laser control system to con-tinuously monitor the fill level of the formand thereby fully automate the fillingprocess. After the mould has been filled, an

oscillating presshead is automatically actu-ated to press and form the product’s spigot.

Hume’s three HawkeyePedershaab MulticastMachines give them great production ver-satility and the capability to manufacture awide array of products. No longer constrained by their former pro-duction method, Humes is free to exploreand bring new pipe styles and options totheir market. Their investment in new andadvanced HawkeyePedershaab vibrationtechnology fits perfectly with their commit-ment to continuing excellence and growth.

Lasse Pedersen, HawkeyePedershaab, BruceRoss, Manufacturing Capital ProjectsManager, and Ron Paterson, ManufacturingManager celebrate the first production offtheir new Multicast Machines, a perfect900 mm pipe.

Humes’ Multicast Machines permit them to manufacture many morepipe each day of a given size as compared to their previous pipemaking methods - a big benefit for customers and for Humes internal production planning.

Humes’ MBK reinforcing cage Type 350 machine, located in the VTproduction hall now serves the new and existing pipe making plants

Humes’ new pipemaking technology permits the production of machine-made lined pipe withthe liner’s locking lugs firmly and dependably embedded into the wall of the product.
