A slide board and a carry strap for patient lift assist (Weiler et al., 2013) were outfitted on every FD gurney to improve access and help reduce lifting loads and risk of strain during the lateral transfer of a patient.
Nonetheless, by reshaping the front wheel wells and adding spoilers ahead of the front wheels, Porsche has reduced lift at the front of the car by 25% and at the rear by 40%, while also increasing brake, engine and transmission cooling.
They concluded that, unknown to the crew, ice had collected on the wings, which disrupted airflow and reduced lift.
To reduce lifting and associated low back injuries, manual material handling operations often involve pulling-pushing of carts at different weights, orientations, and heights.
Specifically, the prototype courier truck was evaluated for its ability to reduce double-handling of packages between carts and the truck, decrease the lifting of carts on/off the truck and reduce lifting packages in awkward positions.
Mechanical lifting devices are recommended as an important intervention for reducing lifting injuries among nursing personnel; previous research suggests that spinal loads are not minimized for all device types.
It stays fairly straight when stretched taut (stretch any tape from the middle of its width, rather than along one edge, to reduce curving) to automatically continue a straight line and may reduce lifting of little bits of plastic, i.e., burring, at the cut edge.
Excessive ice on wings reduces lift, sometimes to the point of causing a plane to crash.
At that point, shockwaves develop on the wings, interrupting the flow of air and reducing lift.
For example, on airplane wings, water vapor turns to ice, adding weight and reducing lift.
