Manitowoc Crane TGL, TGM 2013 Technical Manual

You’ve got a TGL or TGM chassis sitting in your bay and someone wants to mount a body on it. Maybe it’s a dump body, a crane platform, or a utility box. If you skip the legal framework and the axle load calculations, you’re setting yourself up for a liability nightmare. This Manitowoc Crane TGL, TGM 2013 Technical Manual is the only document that gives you the factory body mounting directives straight from the manufacturer. 169 pages of what you actually need: validity conditions, homologation process, product identification, and the math behind axle loads and wheel circumferences. I’ve seen aftermarket copies that leave out half of Section 1.2 – the legal responsibility part that keeps you out of court. Don’t guess. Get the real factory document.

Validity and Legal Conventions: Why This Matters

Section 1 covers validity and the entire homologation process. It spells out your responsibilities as the modifier – section 1.2.2 on responsibility, 1.2.3 on quality assurance, and 1.2.6 on approval. If you’re a shop owner, you need to read 1.2.9 (safety) and 1.2.10 (instructions for bodybuilding companies) before you even touch a wrench. The manual is dated 2013, version 1.0, and applies specifically to the Trucknology® Generation L and M (TGL/TGM). Without this, you have no legal backing for the modification. Page 3 outlines the liability limitations for accessories and spare parts. That alone can save your business if something goes wrong down the line.

Product Identification: Decoding Your Chassis

You need to know exactly which variant you’re working on. Section 2.1 breaks down product designation, wheel formulas (6×2, 4×2, etc.), door designations, and variant suffixes. Section 2.2 walks you through type numbers, vehicle identification numbers (VIN), and base vehicle numbers. If you mix up a rear-axle configuration or miss a suffix, the entire body mounting geometry is off. The manual also lists cab variants (2.4) and engine variants (2.5) – both critical when calculating weight distribution and center of gravity. Don’t rely on a generic aftermarket VIN decoder; this manual gives you the specific coding for TGL/TGM models.

Axle Load Calculations: Don’t Skip This

Section 3 is where the real engineering lives. Section 3.1 covers axle overloading and unilateral loading – a common cause of tire blowouts and frame cracks. Section 3.2 specifies the minimum front axle load required for safe steering and braking. The manual gives you formulas for theoretical wheelbase, overhang, and theoretical axle center (3.5). You’ll also find procedures for calculating axle loads and weighing (3.6). Every body shop I’ve seen that ignored these specs ended up with a truck that wanders on the highway or fails a DOT inspection. This manual doesn’t give you a single number to memorize – it teaches you how to calculate the loads for your specific setup. Use the tables for wheel circumference (3.3) and permissible overhang length (3.4) to check your design before cutting steel.

Post-Mounting Adjustments and Checks

Section 3.7 details the control and adjustment operations required after body mounting. This includes checking toe, camber, and ride height after adding weight. The manual references the factory alignment specs – you won’t find these in any aftermarket supplement. Page 27 lists the specific checks. I’ve had techs call me saying, “The truck pulls left after we mounted the box.” Nine times out of ten they skipped the post-mounting alignment because their generic manual said it wasn’t needed. This one tells you exactly when and how to re-check. Follow the sequence: weigh the vehicle, compare to calculated values, then adjust suspension components to bring everything within tolerance.

Does This Manual Cover the Fuel System?

No. This is a body mounting directives manual – it covers chassis modifications, not engine or transmission work. If you need the engine control specs for the D08 or D0836 engines, look at the MAN D08 Diesel Engine EDC MS 6.4 Technical Manual or the MAN D0836 LE 401 MMDS Technical Information. For the manual transmission itself, refer to the OEM documentation for Manual Transmission overhaul procedures. Keep each manual in its lane. This one stays in the body mounting bay.

Source Authenticity: OEM vs. Aftermarket

The file name on the original is MAN_TGL-TGM_2013_Technical_Manual_fr-30013017284.pdf. That’s the official MAN Truck & Bus publication, printed by the manufacturer. The copy on our site is a direct scan of that document – no reprints, no third-party rewrites. Every table, legal notice, and torque value matches what the factory sent to dealerships. I’ve compared aftermarket versions that rearranged the sections and dropped the legal disclaimers. That’s a lawsuit waiting to happen. If you’re working on a TGL or TGM chassis, use the factory document. Period.

FAQ

Is this manual in English?

The original is in French. The data tables and diagrams are language-independent, but the legal sections require translation if you don’t read French.

What page has the axle load calculation formulas?

The formulas start in Section 3.5 on page 24, with worked examples continuing through page 27. Section 3.6 on page 27 gives the weighing procedure. You need to read all of Section 3 to apply them correctly – no skipping chapters.

Your shop needs this manual if you do any body mounting on TGL or TGM trucks. It’s 169 pages of factory directives that cover legal liability, product identification, axle load math, and post-mounting adjustments. Skip the guesswork and the liability risk. Access the Factory Manual and keep it in your service library for the next job.
