Quality, hard work and love for minute details are the pre-requisites for attaining excellence. The perfection that makes the Hirvin injury transportation sheets quite distinguishable could be attributed to the successful achievement of craftsmanship. The response of all the sheets to superior standards of quality is guaranteed by the scrupulous controls. The Spencer Logo, across the globe, is a symbol of superior quality. Enough attention was given to the ergonomic perspective, at the time of realization of the Hirvin injury transportation sheets. This takes into account the actual structural dynamic situations, as at the time of usage by the operator. Manageability and robustness of the product are expressed by the invisible details. 550 D nylon double coated with poly-vinyl (Spentex®) constitutes the framework, weight and composition of the product. Breaking load under traction 600 kg [1322 lbs] is attached to a 50 mm nylon tape. Softness is increased by a finishing to this material.
