Year of construction 2010, pressing force 80 tons- 8-fold cross tying system

A machine for special material flows, a new challenge for the OBM team. The customer makes high demands. Plastics, buckets, canisters, barrels, Big Bag´s, RDF, shredder fractions etc. should be pressed into compact bales. There are many reconditioned balers on the market, says Jörg Andresen, sales manager at OBM, but in terms of quality, reconditioned balers show a huge disparity.

In order to press such materials dependable into perfect bales, the focus has to be on functionality, stability, dimensional accuracy and professional overhaul of the components.

According to Andresen, not only the brand, but also the know-how of the neuralgic points that must be taken into account when overhauling are essential for the perfect bale. For many years, our OBM works team has been a guarantor for high-quality overhauled used machines.

  • Baler in operation before disassembly and takeover by OBM.
  • The baler was cleaned and dismantled down to the base frame.
  • The press channel (cover with side swings and channel clamp) was dismantled for overhauling.
  • After checking the material thickness of the press floor, we decided to replace the entire substructure of the press channel.
  • All hydraulic lines and electric cables have been removed.
  • After checking the material thickness of the side walls in the press area, we decided to remove and replace the side walls.
  • Overview picture of the press frame after cutting out the side walls, cutting off the press floor and welding in the new steel parts.
  • Detail picture of the newly welded side walls and the frame bridge.
  • Overview picture of the newly welded bottom with side angles of the press channel.
  • Detail picture of the newly welded side walls with needle bushings and the new frame bridge.
  • Welding the new steel substructure from the press channel to the main frame.
  • The main frame is in good condition and will be sandblasted, primed and repainted after the welding process.
  • The base plate of the twist unit was sandblasted, primed, painted and fitted with a new wear-resistant plastic plate.
  • All drill shafts were cleaned, overhauled, re-stored and reassembled.
  • The hydraulic tank was completely emptied, cleaned, all service cover seals, oil and air filters renewed and the tank with attachments repainted.
  • The hydraulic block was dismantled, disassembled, all seals renewed, the catridge valves checked and partially renewed.
  • The press frame is back from sandblasting, priming and painting. The overhauled hydraulic unit has already been installed.
  • Rear view of press frame. The two rails for the press ram were also renewed throughout.
  • View of pressing space under the prepress flap. All wear rails were cut out and new welded in again.
  • View of press chamber to the press channel. The side walls and the bottom were cut out and welded in again. The frame bridge was renewed.
  • The complete steel substructure including the press floor was renewed, the side wings were overhauled and new bearings welded in.
  • View of the press frame, with the elevations and the new bolts for the bale clamp and the side wings.
  • Preparing to install the cable conduits for the new electrical system. Install the new holders for the hydraulic lines.
  • Main hydraulic cylinder after overhaul. Piston rod and cylinder barrel were checked, all seals were replaced.
  • Cylinder of the pre-press flap and of the press channel. All piston rods and cylinder tubes were checked, all seals renewed.
  • Needle box of the vertical tying unit after sandblasting, priming and painting.
  • Needle box of the vertical tying unit for the assembly of new bushings, bearings and deflection rollers.
  • Completely overhauled vertical drill unit with new plastic guide plate, overhauled drill shafts, new bearings, drill fingers, etc.
  • Completely overhauled horizontal drill unit with new plastic guide plate, overhauled drill shafts, new bearings, drill fingers, etc.
  • Overhauled drive motors for vertical and horizontal tying unit. Motors electrically checked, brakes renewed, gear oil changed.
  • Preparation of the new bolts for the final assembly of the side wings, the cover and the bale clamp of the press channel. Press elevations after painting.
  • The wire stations were prefabricated and adjusted with white plastic yarn.
  • The pre-press flap with feed chute, the needle boxes vertical and horizontal were mounted.
  • The electrics and hydraulics are installed.
  • The bale channel with the side wings, the cover and the bale clamp was mounted.
  • The drive motors for the needle train and the twist unit were wired and connected.
  • The worn base plate of the press stamp was welded on and face milled again, the track rollers and lateral guide rollers were replaced.
  • The track rollers were equipped with a new central lubrication system.
