Page 11: General Tolerances
General tolerances Unless indicated otherwise, GreenSteering produces all its products according to general tolerances: For plate and tubing: DIN ISO 2768-1m For turning and milling: DIN ISO 2768-1f These tolerances are also applicable to the installation of the system. Measuring points GreenSteering uses the centre point of the kingpin as the zero point and always measures from the Y-axis... -
Page 12: Production Process
RODUCTION PROCESS Depending on the production process in your company and the construction of the chassis, you can choose a version with bolt-on or weld-on assembly plates. A fully integrated system without using the GreenSteering assembly plate is also possible. GreenSteering steering module is always bolt-on. -
Page 13: Preparation Of The Chassis
REPARATION OF THE CHASSIS Hole pattern in the underside of the chassis During the preparation phase of the chassis, a number of holes are required. This depends on: The type of steering. The choice of weld-on, bolt-on or without assembly plate. ... -

Page 16: Welding Parts On The Chassis
Welding parts on the chassis Warning: As every chassis can be constructed in a different way, GreenSteering cannot provide the yellow- marked parts and needs to be produced by the constructor. Steering module (Xm) The steering module must be assembled to the chassis in tensionless condition. Construct the structure of the chassis in such a way that no torsion can occur at the steering module. - Page 17 If the cross bars are attached to the steering module, it must be assured that these are completely adjacent and no tension must be caused in the steering module when attaching the eight bolts to assemble the steering module. In other words: the cross bar must support the steering module along the whole width and may not cause tension in the casing.

Page 18: Weld-On Assembly Plate Steering Axle (Ab)
Weld-on assembly plate steering axle (Ab) See Chapter 7.1.1 for the main dimensions of types XST11A – XST21A – XST31A with weld-on assembly plates. See Chapter 7.1.2 for the main dimensions of the types XST22X – XST22XW – XST32X with weld-on assembly plates. - Page 19 Reinforce the plates on top with the provided gusset plates. Finish welding according to the image below, or reinforce the chassis so that at least the same effect is reached. Warning: Except for attaching possible assembly plates for lubrication or other pipes, each adaptation to the axle frame must always be approved by GreenSteering in writing.

Page 20: Weld-On Rear Steering Bridge (Ab)
Weld-on rear steering bridge (Ab) Position The position of the rear steering bridge is always measured from the centre line of the rear Y/Y axis. The two holes for attaching the cable pulleys are 515 mm behind the centre line Y/Y The height (H3) is always equal to the steering wing above the steering axles. - Page 21 The weld-on steering bridge must be shortened to the size between the flanges of the chassis. Divide this size by two and measure from the centre point of the steering bridge left and right, in order to shorten both ends. The steering bridge has axis markings to indicate the axis with respect to the chassis.

Page 22: Determining The Height Of The Steering Wing(S) And Rear Steering Bridge (H3)
Determining the height of the steering wing(s) and rear steering bridge (H3) XST11A – XST21A – XST31A Place the steering wing(s) and rear steering bridge as high as possible, taking the height of the cross bars and floor thickness into account. This in order to keep the angle of the cable between the steering module and the steering axle as small as possible. -

Page 28: Weld-On Or Bolt-On Assembly Plates (Af & Ab) Provided With Supporting Plates
Weld-on or bolt-on assembly plates (Af & Ab) provided with supporting plates To resist the shearing forces of the turntables on the assembly plates these can be provided with four supporting plates per turntable. The instructions are below. Due to the big tolerance on the turntables size D1 may differ per delivery. -
Page 29: Preparing The Axle Frame
REPARING THE AXLE FRAME Preparing the axle mounting Weldable axle boxes and possible assembly plates for the air bellows are welded to the axle frames during the preparation. H1, H2 and L1 are depending on the axle type. L2 must be filled up, depending on the axle type. Place the axle boxes and air bellow assembly plates according to the drawings and assemble, reinforce and weld or bolt the axle boxes according to the assembly regulations of the axle manufacturer. -
Page 30: Preparing The Steering Wing (Af And/Or Ab)
Preparing the steering wing (Af and/or Ab) Because the steering wing is always supplied to mount at maximum height, it is possible that the assembly profiles need to be shortened on both sides. Steering wing(s) with weld-on steering bridge Universal rear unit with steering wing: New rear unit without steering wing. -
Page 31: Shortening The Steering Wing(S)
Shortening the steering wing(s) Shortening the steering wing (Af and/or Ab) (only if necessary). Limit the shortening of the steering wing to a minimum. Only saw or grind the part that can be removed if this is really necessary and do this in stages of 40 mm or a multitude of this, so the saw cut is always 24 mm under the lowest holes to use. -
Page 32: Preparing The Assembly Of The Turntable
Preparing the assembly of the turntable To resist the shearing forces of the turntables on the assembly plates these can be provided with four supporting plates per turntable. The instructions are below. Due to the major tolerance on the turntables size D2 may vary per delivery. -

Page 34: The Cables
HE CABLES XST11A – XST21A – XST31A The cable has a diameter of 16 mm. The cables that guide the axles start at the steering module and go via the sprocket up to the steering wing on the axle bearing. When measuring the cables in the chassis you must take account of the fact that the cables move inwards over a distance of 100 mm at the steering module and the steering wing when turning. -
