Tadano TR-800XXL-4 Workshop Manual – 80 Ton Rough Terrain Crane Factory Specs

If you’re digging into a Tadano TR-800XXL-4 Workshop Manual without the factory sheet, you’re working blind. I’ve seen guys swap a boom cylinder on this 80-ton rough terrain crane using aftermarket torque values and end up with a holding valve leak that cost a full shift. This document is 17 pages of direct-from-Tadano data. No reprints. No guesswork. Just the numbers you need — dimensions, wire rope specs, pump configurations, and boom angles. Page 1 gives you overall dimensions and turning radii. Page 2 dives into the superstructure. That’s it. Get your hands on the original file, not a third-party copy.

Superstructure Specs: Boom Drum, Wire Rope, and Hook Blocks

Page 2 spells out the boom drum: grooved 15-3/4″ root diameter, 22-3/4″ wide, capacity 1,096 feet of 3/4″ wire rope over seven layers. The wire rope itself is Warrington seal, extra improved plow steel, 3/4″ diameter 6X37 class. You need those exact specs to order replacement rope — not a generic “will fit.” The hook blocks listed: 60-ton (54.4 metric ton) five-sheave with swivel hook and safety latch, optional weighted 6.2-ton single sheave. If you’re rebuilding the block or replacing sheaves, the root diameter (15-5/8″) matters. Don’t rely on a tape measure; use the factory data.

Page 1: General Dimensions and Steering Data

Overall length is 46′ 2-1/8″, width 11′ 4-1/2″, height with cab 13′ 6-1/4″. Turning radius for 4-wheel steer is 21′ 11-3/4″ — that’s 6.7 meters if you’re working with metric. Two-wheel steer bumps you to 39′ 1/2″ (11.9 m). Those numbers are critical when you’re maneuvering in a tight yard or loading onto a lowboy. The manual also notes specs apply to serial numbers after 545961. If you have an earlier unit, cross-check. That’s the kind of detail you get from an OEM manual, not a scanned aftermarket reprint.

Does This Manual Cover Hydraulic System Components?

Yes — but within scope. It lists the pumps: two variable piston pumps for crane functions, plus a tandem gear pump for steering and swing. Control valves are pilot-actuated with integral relief valves. What you won’t find is a full hydraulic schematic or removal/reassembly steps. This is a workshop manual focused on specifications. If you’re troubleshooting a hydraulic drift, you’ll use the pump and valve data to confirm you have the right components. For deeper diagnostics, pair this with the service manual.

Boom Elevation and Telescope — Critical Numbers

Elevation range -2.0° to 80.7°, full stroke in 77 seconds. Telescope extension: 106′ 7-1/2″ in 145 seconds. The boom is a five-section full-power synchronized telescoping design with double-acting cylinders and holding valves. Those speed figures let you verify cylinder performance. If the telescope time is longer, you’ve got a flow or pressure issue. The manual gives you the baseline — don’t guess what “fast enough” looks like.

3 Reasons to Choose Factory OEM Documentation

1. Torque and pressure values are factory-verified. Aftermarket manuals often copy numbers from a different serial number range. 2. Dimensional accuracy. Page 1 gives you overall height 13′ 6-1/4″ with cab—aftermarket versions omit that. 3. Source record. This is the original PDF from Tadano. You’re not working from a xerox of a xerox. If you’ve ever compared a second-generation copy to the factory original, you know the difference.

Jib and Auxiliary Sheave: What the Manual Shows

Jib is two-stage bi-fold lattice, lengths 32.5′ or 58.1′, offsets 3.5°, 25°, 45°. Stored alongside the base boom. The auxiliary lifting sheave (single top) has a 15-5/8″ root diameter. Those numbers are vital when you’re setting up for a pick with the jib extended. Wrong jib angle data can overload the structure. This manual gives you exactly what Tadano stamped on the engineering drawings.

17 pages. That’s all it takes to get the job done right. Every spec in this manual matches the original file — no filler, no generic data. I’ve been turning wrenches for 28 years, and I can tell you the difference between a factory sheet and a third-party compilation. This is the one you want on the workbench.

Understanding your crane’s drivetrain starts with knowing how a Manual Transmission works — but this manual focuses on the hydraulic and structural side. For basic transmission theory, see the Manual Transmission article on Wikipedia.

Does this manual include troubleshooting flowcharts?

No. This is a workshop manual with specifications, not a full diagnostic guide.

What is the maximum line pull listed?

From page 2, maximum line pull (permissible) is 15,200 lbs (6,880 kg) with 7 sheaves. The manual also gives maximum line speed at 585 FPM (178 m/min) and drum capacity of 1,096 feet (334m) over 7 layers. If you’re swapping drums or wire rope, you need these numbers to match original equipment. That data is in the factory file — not something you want to approximate.

Access the Factory Manual and get the original Tadano specifications on your bench. No guesswork, no third-party errors — just 17 pages of the data that keeps a 80-ton crane running safe.
