Every fleet. 17 product categories and 1,342 engineered designs in this family alone, every one backed by a QMW engineering drawing. If your machine isn't in the library, we design against the standard it has to survive, then break one to prove it. - Truck (on-road) ROPS / FOPS308 designs - Excavator ROPS / FOPS262 designs - Roller ROPS / FOPS194 designs - Loader ROPS / FOPS153 designs - Other machine ROPS / FOPS94 designs - Dumptruck ROPS / FOPS70 designs - Dozer ROPS / FOPS63 designs - Tractor ROPS / FOPS60 designs - Drill rig ROPS / FOPS38 designs - Grader ROPS / FOPS19 designs - LHD (underground) ROPS / FOPS17 designs - Mower ROPS / FOPS16 designs - Forklift ROPS / FOPS16 designs - Crane ROPS / FOPS14 designs - Backhoe ROPS / FOPS10 designs - Skid steer ROPS / FOPS6 designs - Telehandler ROPS / FOPS2 designs Why QMW ## Designed. Tested. Proven. ### Designed in-house **Over 2000 ROPS and ROPS/FOPS designs** in our library, with new designs added continually. Every structure is modelled against the standard it must survive before steel is cut. ### Destructively tested Loaded past the point of failure in our **NATA-accredited laboratory**, because the only way to prove a cab protects an operator is to break one deliberately. ### Installed anywhere **QMW site crews install ROPS anywhere in the world.** From single machines to whole-fleet programmes, on your site and on your schedule. ### Supply-only ready A **comprehensive installation procedure manual** ships with every ROPS model, so your own crews can install on a supply-only basis with full confidence. How a structure earns its plate ## From load case to certificate ### Model the load case Our engineers model every structure against the standard it must survive: machine mass, energy absorption, deflection limits. ### Break one on purpose The design is loaded to destruction in our NATA-accredited laboratory. No simulation stands in for steel. ### Ship it with proof Every structure leaves with the certification documents to back it. ISO 3471 compliance, documented end to end. Also available: **certified ROPS cabin repairs**. Damaged protective structures assessed, repaired and re-certified rather than scrapped, where the engineering allows it.
