Rule 6.4 Driver’s Protective Cage

From Reference
Jump to: navigation, search

Each buggy shall be constructed with a structurally sound cage which totally surrounds the driver. The purpose of this cage is to help protect the driver from front, side, rear, and rollover impacts in the event of an accident. The driver’s protective cage shall meet the following minimum requirements:

  • NO PART of the driver’s body shall extend beyond the protective cage.
  • The interior of the protective cage shall not have any sharp edges, pointed objects, or protruding objects, which could injure the driver in the event that the driver is pushed into or thrown against these edges or objects.
  • None of the wheels of the buggy shall be considered to be part of the driver’s protective cage.
  • The protective cage shall be designed and constructed in such a way that injury to the driver will be minimized in the event that one or more of the buggy’s wheels become detached from the buggy, while it is moving.
  • The protective cage shall be designed and constructed in such a way that a 1.0 inch wide by 72 inch long infinitely stiff bar, held in ANY position in a vertical plane perpendicular to the centerline of the buggy (this means with the bar’s axis vertical, horizontal, or at any angle,) will not intrude into the front of the cage, nor contact any part of the driver’s body, nor increase the force distribution on the driver’s body, when pushed toward the buggy with a force of 1,000 pounds, while the buggy is restrained so that it cannot move.
  • The protective cage shall be designed and constructed in such a way that a 2.0 inch wide by 12 inch long infinitely stiff bar, held in ANY position (see preceding paragraph) in any vertical plane that is either perpendicular to or parallel to the centerline of the buggy, will not intrude into the sides or rear of the cage, nor contact any part of the driver’s body, nor increase the force distribution on the driver’s body, when pushed toward the buggy with a force of 500 pounds, while the buggy is restrained so that it cannot move.
  • The protective cage shall be designed and constructed in such a way that it shall not collapse or deform such that any part of the driver’s body would be contacted (by the cage or by the steel plate,) if a 2 ft. by 5 ft. by 1.00 inch thick steel plate was slowly lowered onto the top of the buggy. (This plate weighs approximately 408 pounds.)
  • If a buggy has a pushbar that can change its position (this means that it is not rigidly and permanently attached to the buggy,) that pushbar shall NOT be considered to be a part of that buggy’s protective cage. Any buggy with such a pushbar, must meet all of the requirements for the driver’s protective cage with its pushbar in any of its possible positions. This is to ensure that the pushbar itself, will not cause an injury to the driver in the event of an accident.
  • The protective cage shall be designed and constructed in such a way that no part of the driver’s body shall be exposed to the road surface. The purpose of this requirement is to ensure that there is some substantial structure protecting the driver from below in the event that the bottom of the buggy comes in contact with another object, such as if the wheels came off and the buggy slid along the ground.
