Excavator Mechanical Quick Hitch Coupler 1–18 Ton MQC30 to MQC70 Bucket Coupler

Product Overview

The Mechanical Excavator Quick Hitch Coupler is a professional-grade fast attachment system engineered to eliminate the time, effort, and safety risks associated with manual pin-on attachment changes on excavators ranging from 1 tonne to 18 tonnes. Designed for direct installation onto the excavator's dipper arm using the machine's existing pin configuration, this mechanical quick hitch coupler allows operators to switch between buckets, hydraulic hammers, augers, compaction plates, rippers, and other pin-on attachments in a fraction of the time required by conventional manual methods — without the operator needing to leave the cab, handle heavy pins under load, or expose ground personnel to the swing radius of the machine during the changeover process. For contractors, plant hire companies, and civil works operators who regularly change attachments across multiple machines and job types, this quick hitch coupler delivers measurable gains in productivity, safety, and operational flexibility from the first day of use.

The core productivity advantage of a mechanical quick hitch system lies in its ability to transform attachment changes from a multi-person, multi-minute manual operation into a single-operator task completed in under a minute from the cab. On busy construction, demolition, trenching, or bulk earthworks sites where attachment changes occur multiple times per shift, the cumulative time savings across a working week or project duration are substantial — reducing non-productive machine time, lowering labour costs associated with ground crew assistance, and allowing the excavator to remain on task for a greater proportion of each working day. The mechanical design also eliminates the hydraulic lines, solenoids, and electrical connections required by hydraulic quick hitch systems, resulting in a simpler, more robust, and lower-maintenance solution that performs reliably in the harshest site conditions without the risk of hydraulic failure or electrical fault.

Five model configurations are available to cover the full range of excavator classes commonly used in civil construction, mining, and general earthworks. The ME-MQC30 (384 × 202 × 215 mm, 31 kg) suits 1–2 tonne mini excavators used in confined access, landscaping, and utility works. The ME-MQC40 (450 × 234 × 241 mm, 43 kg) is designed for 2–3.5 tonne compact excavators widely used in residential construction and drainage works. The E-MQC50 (612 × 312 × 271 mm, 71 kg) covers 6–8 tonne mid-size excavators suited to road works, bulk earthworks, and general civil construction. The E-MQC60 (616 × 392 × 327 mm, 114 kg) is engineered for 10–14 tonne excavators used in heavy civil, pipeline, and foundation works. The E-MQC70 (796 × 512 × 396 mm, 179 kg) serves 16–18 tonne large excavators deployed in quarrying, mining, and major infrastructure projects. Each model is dimensionally matched to the pin spacing and bracket geometry of its target excavator class for a precise, rattle-free fit.

All models in the MQC series are manufactured from high-strength structural steel to withstand the dynamic impact loads, cyclic fatigue stresses, and abrasive conditions generated during continuous excavation and material handling operations. The mechanical locking mechanism provides a positive, audible confirmation of secure attachment engagement, giving the operator confidence that the attachment is fully locked before commencing work. The coupler is designed with a safety retention system that prevents accidental attachment release in the event of operator error or unexpected load reversal during digging, lifting, or grading operations — a critical safety feature that distinguishes professional-grade quick hitch systems from lower-specification alternatives in the market.

The Mechanical Excavator Quick Hitch Coupler is suited to a wide range of applications including bulk earthworks, road construction, trenching and pipeline installation, demolition, land clearing, mining and quarrying, and general civil construction across all excavator size classes. Custom configurations and non-standard pin sizes are available upon request for machines with non-standard bracket geometry or specialist attachment requirements.
