U形架在与J形架相反的方向上使用,因为在框架的弯曲区域,“腿” 总是指向远离用户的位置,将支架夹在线束或锚上。 U形架不会像J形架那样通过掉落或增加杆来促进摩擦变化,并且U形架绝不应使用少于4个杆。 SMC设计的4 bar u型机架的好处是具有两个相对的系杆。 这为更快的捆绑方法提供了机会 (用户可以像使用船夹板一样在2个销钉之间编织绳索),并且用户可以在更短更轻的系统上具有更多 “微调” 的摩擦可能性。

附加信息

If you want to start a heated debate among Rappel Rack aficionados just ask the group what style is best, J-Racks or U-Racks? Both share benefits such as providing the largest range of friction control with a variety of ropes, being great as either a lowering device or on rappel, not twisting ropes and so on. The benefit that people most often attribute to the U-Rack over the J-Rack is greater strength. This is a fallacy, despite being the common understanding, as the system fails when the rope brakes rather than the device breaking. As a result, both types of racks achieve similar ratings.

  • SMC U-Rack assemblies are the only such U-Racks which are UL Certified to the current NFPA standards.
  • U-Rack may be used as either a rappel or lowering device.
  • U-Rack provides for even distribution of weight between both sides of the rack.
  • U-Rack does not twist rope, as can occur when using a Figure 8 type descender.
  • U-Rack may be used with single or double ropes of varying diameters.
  • Different length racks provide wide range of friction and control under varying weights and applications.
  • User may adjust friction by simply wrapping rope around the Tie-Off Bar(s).
  • Stainless steel rack material provides greater strength, reliability and long lasting service.
  • Tie-Off Bars are tubular stainless steel for longer life.
  • Brake Bars are available as aluminum or stainless steel and come in a variety of styles and sizes.
  • Racks & bars may be purchased separately so that the user may have a greater range of set-up configurations tailored to meet their individual needs for non-NFPA applications and as replacement parts.
