1. Product overview

Quick answer: MAGEON MG500B is a 6-ton steel track crawler undercarriage with a 300 mm track width and a 2118 mm frame length. It is built to the host machine's mounting interface rather than selected from a catalogue, and every assembly ships with material traceability and a video outgoing inspection.

The 5 to 10 ton class is where the crawler undercarriage stops being a consumable and starts being an engineered system. Loads are high enough that fatigue in the frame and chain becomes a design driver rather than an afterthought, yet the machines still operate on mixed ground where a heavy steel-only specification is wasteful.

MG500B is a 6-ton steel track chassis with a 300 mm track width and a 2118 mm frame length. Compared with the model below it in the series the frame grows by -132 mm in length and the track widens by 0 mm, which is the usual upgrade path when the machine gains payload or works on softer ground.

3. Design features

High-Strength Welded Frame

Q345B high-strength steel throughout the beam and cross members, with the welded structure optimised for load capacity and torsional rigidity. Fatigue life is planned against the duty cycle rather than a static rating.

Rubber Track and Steel Track in the Same Class

Every tonnage from 5 to 10 tons is available in both rubber and steel variants, because ground conditions vary faster than machine weight does. A fleet running on paving and a fleet running on quarry floor need different answers at the same tonnage.

Matched Ground Pressure

Contact length and track width are set together against the working ground bearing capacity. On soft ground the MG1000 class, with 400 mm tracks, keeps ground pressure low enough to work where a narrower chassis would bog down.

Sealed and Lubricated Running Gear

Pre-lubricated sealed rollers and idlers extend service intervals in dust and mud, and every chassis ships with material traceability for the Q345B beam.

4. Typical machine applications

Common machine types matched to this class:

· Mid-size excavators

· Wheel and crawler loaders

· Rotary drilling rigs

· Crawler cranes

· Compactors and graders

· Mining support equipment

· Farm machinery

5. Series overview

The Medium-Duty Crawler Undercarriage series covers 10 models from MG400A to MG1000B. The table below lists the full series so the MG500B can be positioned against adjacent tonnage classes before a specification is fixed.

6. Dimension reference

The A/B/C/E dimensions above define the chassis envelope and D defines ground contact width. A longer A improves stability and reduces frame bending under load; a wider D lowers ground pressure but widens the machine. Both are selected against the host machine's weight distribution and its installation envelope, not against the catalogue.

7. Selection notes for this tonnage

· Frame fatigue life scales with the number of load reversals, not with hours. A machine that lifts and slews continuously will exhaust a frame sooner than one that travels the same distance.

· On the 5-10 ton class, ground pressure is usually the limiting factor for soft ground access, and it is controlled by contact length before it is controlled by track width.

· Specify sealed and pre-lubricated rollers when the machine works in abrasive dust. The cost of the upgrade is recovered long before the first bearing replacement would otherwise come due.

9. Frequently asked questions

Q1: What is the difference between MG1000A and MG1000B?

A: Identical frame dimensions and 10-ton load capacity. The A variant is fitted with rubber tracks for paved surfaces and low ground pressure; the B variant uses steel tracks for abrasive and heavy-duty ground.

Q2: Can MG800 be used for a crawler crane?

A: Yes, with the option of an integrated slewing bearing for 360-degree rotation of the upper structure. The 8-ton class suits smaller crawler cranes where a separate slew ring would be over-specified.

Q3: Do these models ship with hydraulic motors?

A: The drive package is specified per project — hydraulic, electric or mechanical. The complete assembly including motor and travel gearbox can be delivered matched to your system parameters.

10. Customization and OEM service

MAGEON supplies the MG500B class as a complete assembly and accepts customer drawings or measured samples for interface-controlled builds. The following parameters are configurable within the model envelope:

· Track width and frame length adjusted to the machine envelope

· Drive type: hydraulic, electric or mechanical

· Travel gearbox: single-speed or dual-speed

· Integrated slewing bearing for 360-degree upper-structure rotation

· Custom mounting flange, bolt pattern, drive shaft height and hydraulic interface

· Colour: black or specified

Next step: send the machine weight and load distribution, the mounting interface dimensions, the required travelling speed, the ground conditions and the drive configuration, and MAGEON returns a configuration and price within one working day of a technical enquiry.
