Wing seat

Wearing seat belts is essential for operator safety. Figure 9-4 illustrates wing seats and seat belts on this lift truck. 

For this reason, seat belts on counter-balance trucks have become the norm. In addition to a seat belt is a modified operator s seat that includes a wrap-around shoulder support system, referred to as a wing seat. On other models, the base of the seat may be modified to include bolsters on each side to prevent the body from sliding out of the seat during tipover. The operator would still have to brace his feet, hold onto the steering wheel, and lean away from the tilt. It should be noted that a tipover occurs in approximately 1.5 seconds. This does not provide much time for anyone to plan response actions once the tipover has begun. As a result of the seat and seat belt improvements, the operator is provided with an added margin of safety. 

The wing seat concept was first developed by Clark Equipment Company in the early 1980s. They funded research to determine what could be done to prevent tipovers. They began the research with ideas about what devices should be placed on lift trucks to protect operators during tipover. 

Perhaps the most dramatic evidence to date supporting the use of forklift seat belts is the survival of a lift truck operator after a 40-foot fall. The operator was moving a pallet load of air compressor motors on the fourth floor of a warehouse when the floor collapsed. The forklift came to rest on its side. The overhead guard and the fact that the seat belt on a winged seat was used is credited with saving the life of the operator. The debris of the falling floor completely covered the lift truck. It took rescue personnel four and one-half hours to free him from tangled concrete and steel. 

In another situation an operator at a warehouse dock was saved from serious injury because of a wing seat. A trailer pulled away from the dock too soon, before the last pallet was loaded. The front wheels of the lift... 

Some have argued that operator training is the key to preventing injuries and fatalities during tipovers. Is training more basic than seat belts and wing seats Can an employer rely on each operator to follow prescribed safety rules provided in the classroom Many safety professionals insist on both training and the use of safety equipment. 

Tipover usually occurs because of operator error. As an added safeguard to counter operator error, the wearing of seat belts and the use of wing seats make sense. Despite the fifteen years of operator-seat modifications and seat belt installations on counterbalance lift trucks, the toll of injuries and fatalities continue. The seat belt may not be a perfect device that is readily accepted by operators and management, but the use of such safety devices surely contributes to reducing the numbers of injuries and deaths. The use and enforcement of these devices should be a part of every operator s training.

Winged seat A seat with wing-like protrusions near the operator s upper torso usually refers to the Clark winged seat (Clark PN 1831394). 

My Guide then seized my hand and bade me follow him to the next Chamber. When I had penetrated through the veil which closed the entrance, again I saw a throne upon which a Woman was seated, clothed in Majesty, and wearing the Crown of Authority. By her side was an Eagle, and above her was a canopy which seemed to be formed of the Wings of Angels.

Within the aerospace industry, advanced composites are used to greatest extent in military aircraft. Commercial aircraft such as the Boeing 757 and 767 contain less than 5% advanced composites by weight, while military aircraft like the GA-18A contain 10%-20%. Typical applications of composites include aircraft wings, tail sections, pressure vessels, and seat rails.
