Balers being produced at the factory in the Netherlands

Certified refurbishment process
that meets all your needs

Only Bollegraaf can guarantee that a reconditioned baler is built according to factory standards. At our location in Appingedam we have a special overhaul workshop where we overhaul used balers.

When you purchase a Bollegraaf OEM Factory-Certified Refurbished Baler, you can be sure the baler has been fully inspected and is as good as new.

Every pre-owned baler refurbished at our Bollegraaf factory receives a OEM quality compliance certification

General refurbishing principles:

Cleaning and disassembly

The baler is completely cleaned and dismantled in our overhaul workshop.

Tolerances

The tolerances of all steel components are measured and where necessary welded again. At least, this applies to the ram, the frame, the channel and the pre-press flap.

Restoring

The ram is re-welded and fitted with new ram wheels and the protective grids and the pre-pressure flap are made dent-free and repaired where necessary.

Repainting

After measuring the tolerances and any repair and welding work, all components are repainted.

Hydraulics

The hydraulic tank is cleaned and all hydraulic lines & hoses are replaced. The hydraulic components are repackaged while the hydraulic oil is replaced.

Cabling

All cabling is checked and replaced if necessary while all junction boxes are replaced and placed back in easily accessible positions.

Wear parts

All wear parts are replaced. The pins and shafts of the cylinders and the channel are replaced with new ones. All wearing parts of the (both) needle installations and knots are replaced by new ones.

Cylinders

The cylinders are repackaged and, if necessary, provided with a new chrome layer or a new cylinder rod.

Control box

The switch box is checked and cleaned. If necessary, electronic components are replaced with new ones.

5 things to check when buying a pre-owned Bollegraaf baler

Step 1: get an answer on the question when the baler was last running

Like a used car, buyers need to be cautious when purchasing used balers and equipment. You could find the deal of a lifetime or a lifetime of complications. One of the first questions to ask is when was the baler last running in a MRF. If it has been recently moved, ask if it ever ran in that location. Even better, see it running for yourself. If you can’t confirm the most recent run date or see it operating, plan for there to be unknown electrical, hydraulic, and mechanical issues.

Step 2: examine the paint job

necessary structural, mechanical, electrical, and hydraulic components replaced as needed with OEM parts. Other used Bollegraaf balers will not be restored to the same degree of quality and will claim to be rebuilt when all they had was a thorough paint job. If a “rebuilt” Bollegraaf baler has almost every component painted, be diligent and inspect the baler with more detail.

Step 3: measure the frame for structural integrity

One of the biggest indicators of a baler’s condition is in the frame. Check these thicknesses to know if your baler has significant wear:

Step 4: check for hydraulic leaks

If the baler hasn’t been running, seals may dry out and start leaking. Inspect the cylinders to see if there are any oil spots or dribbles on the floor or if oil is leaking down the piston. If there is no oil, the cylinders may have been recently cleaned. Ask to see the baler run to determine if the seals still have integrity. If they are busted, oil will start leaking from them while running and they will need to be rebuilt.*

*All our factory-certified refurbished balers have had their cylinders rebuilt, both flap and main ram ones. We take apart every single cylinder, replace all seals and rebuild the cylinder so it is like new.

Step 5: check whether there is any electrical damage

If the baler has undergone a recent move, always check the electrical. Many times, inexperienced movers will damage electrical wiring when taking a baler out. Inspect the wiring and check to see if any cable sheathings are damaged. Also, older electrical components may no longer be serviced and would have to be upgraded if they are out of date.* If you’re unsure if we still carry the electrical components, call our service department to verify availability.

*Our factory-certified refurbished balers will have completely new wires and up to date electrical components so that unwanted electrical ‘gremlins’ don’t pop up and cause unforeseen downtime.
