'Assignable buttons' is an exclusive feature to PG Drives (R-net electronics) and Quickie Wheelchairs that lets dealers, clinicians, and technicians assign commonly used functions such as tilt-up, tilt-down, legrests-up, legrests-down, etc. The design also optimizes the articulation range of the front and rear casters to give the chair a spider-like ability to crawl onto and over steep transitions without compromising user stability. This independence helps each wheel to maintain constant contact with the ground. The outcome is a clean, efficient power chair that is easy to service and highly reliable.Īs the name suggests, SpiderTrac™ Suspension features independent suspension on all 6 wheels. They also went out of their way to route all wiring inside the chair's modular components. They designed the interface system to accept power lift and tilt modules that easily slot in and out. To ensure easy serviceability, the QM-715 HD design team reduced the number of parts in the wheel base by over 30% from the previous mid-wheel model. The larger actuator motor used on the Quickie QM-715 HD tilt mechanism is 50% larger that the one used on the Quickie QM-710, which is why it is rated for user weights up 400 lbs. This tilt mechanism uses a multi-bar linkage system and linear actuator to ensure that the tilt movement remains smooth and controlled throughout the tilt cycle. This combination of time tested componentry and design innovation provides the basis for the QM-715 HD's outstanding performance. The Quickie QM-715 HD power base is a fresh new design, but it is built with time tested components, including Linix motors and PG Drives® VR2/R-net electronics. Result: a super smooth transition onto or off of most any step or curb. Unlike spring suspension caster systems that often collapse when rolling off a step/curb or locking caster systems that prevent collapse but frequently have a jarring impact, the SpiderTrac™ Suspension uses a gas spring system to dampen the impact without collapsing. The Quickie QM-715 HD SpiderTrac™ Suspension takes the jolt and forward pitching out of everyday step/curb transitions.
