Mounting Notes: Read and clearly understand manual BEFORE beginning ANY work Important!!! The basic rule for installing an ILU PALFINGER Liftgate is to MOUNT THE FRAME AS HIGH AS POSSIBLE to achieve MAXIMUM GROUND CLEARANCE and MINIMIZE THE “F” DIMENSION.
3 Chassis Dimension SheetsChassis Dimension Sheets Chassis Dimension Sheets Trailer Chassis Dimension Sheet Fill out and send to Interlift if specific install drawing is needed A= Bedheight, top of floor to even ground..B= Top of floor to bottom of trailer cross member..C= Rear sill height, top of floor to bottom of buck plate..
Before starting the installation, make sure that you have your own reference sheet that was supplied to PALFINGER Liftgates together with the installation lay-out drawing. Compare it with the truck you are about to start the installation on. If the units are different than the supplied lay-out, contact your supervisor and PALFINGER Liftgates to go over the differences.
4 Installation Dimensions General Bed Height Ranges for ILU liftgates. Minimum bed height is when truck/trailer is loaded to MAX GVW (all dimensions in inches) ILU 40-50 800mm arm 36”- 56” Revision 1.5 - 10 -...
4 Installation Dimensions Chassis and Body Preparation Mount frame clearance 4.2.1 - Determine the correct mounting clearance according to your specific lift and chassis. - With long overhangs it is even more important to maintain Max ground clearance. o GROUND CLEARANCE = BOTTOM OF LIFTGATE FRAME TO GROUND - Determine if you need to move chassis U-bolts or if you have any other interferences, then proceed with installing the liftgate slide rails to the frame IMPORTANT (Truck Installation):...
4 Installation Dimensions Rear sill preparation 4.2.2 To assure that the gate is reaching the body floor, you need to cut out the rear sill of your truck/trailer. • If sill is less than 4“ high No sill cut out needed •...

4 Installation Dimensions • On trailers, you have to check the eyebrow clearance, and in case of interference cut eyebrow down until platform clears. • The eyebrow cut out can be done when gate and platform are installed and you raise up gate for the first time.
5 Gate Installation Gate Installation Never work under mount frame or platform without safety supports Slide rail bracket installation ADD STEEL BACKER PLATE IF MOUNT BRACKET CAN NOT BE WELDED 100%. Figure 7 Slide rail installation 1) Make sure the specific install drawing sent with the liftgate matches the truck and gate you are about to install.
5 Gate Installation Liftgate attachment Figure 8 Liftgate installation to previous installed rails 1) Slide liftgate main frame assembly into previous installed slide rails. 2) Connect pin in front of push-pull cylinder to bracket towards truck cabin. Figure 9 platform attachment 3) Connect platform to frame by using supplied pins and lock bolts 4) Connect lift arm to inside clevis holes.
Control power wiring setup To maintain the best possible power supply, install the auxiliary batteries as close as possible to the gate. - Truck installations might not have an auxiliary battery kit (PALFINGER Liftgates always recommends a kit). In this case you have to run the control power straight off the truck battery.
5 Gate Installation Platform installation To install the platform (if not preinstalled by manufacturer) follow these steps: 1) Unfold platform and clamp on to forklift or overhead crane. 2) Slide out gate to the point that you are able to attach platform clevis to lift arm and tilt cylinders. 3) Bring platform close to gate and attach lift arm to platform using provided pins 4) To attach tilt cylinders hold B-15 platform sensor so that you are able to extend tilt cylinders when turning the tilt switch until you match pinholes on platform and tilt cylinder head...

6 Gate adjusting and detailing Setting B-15 Platform sensor Figure 17 B-15 adjustment on platform • Mount the platform sensor B-15 to the right-hand side of the platform as shown in Figure 18. Make sure to loop wire around to give it enough slack in normal operation and route clear of any pinch points.
6 Gate adjusting and detailing Platform adjusting with bolts At the bottom between the main and the tip section are 4 bolts to adjust the platform. These adjusting bolts are horizontal to the platform. To level the platform the bolts need to be adjusted. To tilt the tip section up the bolts have to be rotated counter clockwise.
When performing electrical installation, be certain to install and secure everything in a way where it is not subject to damage from moving parts, sharp edges, exhaust systems, etc. • ANY deviation from PALFINGER Liftgates’ recommended power setup (see 7 Electrical Installation)

Decal Placement For operator’s safety, all decals appearing in “Decal Kit” must be in a conspicuous place on control side of liftgate to be read by operator. This is typically a combination of decals on the liftgate and truck body. Please make sure to place the maximum capacity decal (D) on driver and curb side. (A) 1 ATG-URGWA - Urgent warning: Elevating gate instructions (B) 1 ATG ILU - Operational Instructions (placed on your Control Box).
