Full-face surface repair for Pave production pallets
Headquartered in the Lower Saxony town of Nordhorn, Pyratec GmbH began to specialize in the overhaul of production pallets many years ago. After successful tests, the Southern German Company Peri decided to cooperate closely with Pyratec in future: as a result, the specialist company will now take on the sustainable renovation of Peri production pallets with immediate effect.
The outstanding characteristics of Peri Pave production pallet is a very reliable element in the manufacture of concrete paving blocks worldwide. The multiplex core construction is produced by the crosswise bonding of individual veneer layers of high‑quality birch wood taken from sustainably managed forests. The polypropylene coating is specially designed for use in concrete block production plants. Since 2007, the second generation of this coating has been used and provides very high impact resistance and abrasion resistance. This ensures a long service life for Peri Pave production pallets.
Extending the service life
Regular laboratory testing of Peri Pave production pallets show that the plywood core is still in very good condition even after many years of use. If the surface of the Pave production pallets has become worn due to production‑related wear and tear, the service life can be extended by means of a full‑face surface repair procedure. Since 2007, the abrasion resistance properties have been significantly improved through the use of polypropylene coating on the Peri Pave. In particular, a full‑surface repair can therefore increase the service life of those production pallets which were delivered up to 2006 and featured the first generation coating. This does not exclude the possibility of also renewing the latest polypropylene coating if necessary.
Customised full-surface repairs
Pyratec agrees on all required repair work individually with each client and holds close consultations about possible repair solutions. For preparing the quotation, at least one reference pallet is inspected and repaired so that the customer can conveniently assess the expected result. Furthermore, it is common practice that the refurbished reference production pallet is tested once again in the production at the concrete block and paving stone plants before a firm order is placed for the repair.
Pyratec basically provides two different repair options with the following process steps and results: “Renocare C” is drying and sanding of the production pallet; filling of cracks and indentations with a multi-component plastic filler, with the result of seamless and perfectly even board surfaces. “Renocare Special” includes the same procedure as for “Renocare C”, with the additional application of a new 1.6 mm thickplastic laminate coating on each side of the board. The result is a seamless, perfectly even and abrasion-resistant board surface through a new plastic laminate coating.
Practical and thoroughly tested
The logistics for refurbishment operations is also efficiently handled and well thought out without any loss of production: processing the pallets is carried out in batches, a full truckload in each case. When the first, refurbished production pallets are transported back to the plant, the other batches follow in stages. This also minimizes transportation costs and requirements.
