重型货架 ，每层承重超过500kg的就属于重型货架了。
横梁式货架是重型货架中的一种，横梁式货架具有100%存储性，拣取效率高，
不受货物出入库先后顺序限制。货架可任意调整组合，层高可任意调节，一般适用于叉车存取。
通常分传统式巷道（3000mm左右）、窄巷道（1700mm左右）两种类型。窄巷道货架需要配备专用
窄巷道叉车。
采用异型截面立柱，提高承载能力
横梁可以以75mm为单位上下调节，使用灵活
组装式框架结构，配备安全附件，折装方便，且便于零部件后期维护、更换
表面通常采用环氧树脂静电喷塑处理，具有很高的抗腐蚀的能力
可根据使用要求配备搁挡、后挡、层板、护脚、护栏、背网等部件
Pallet racking is 100% of the storage ,pick take high
efficiency ,without being limited by the order directly .
Shelves adjusted ,adn generally applies to forkift access.
Usually divided into traditional roadway (3000 mm),narrow roadway two
types (1700mm) .Narrow roadway shelves need equipped with special
narrow roadway.
1.adopt single section pillar,and improve the bearing capacity
2.beams cn adjust up and down for the unit with the 75mm,flexible use.
3.packaged framework structure ,safety accessories ,tear open outfit is
convenient,and easy maintenance,replacement parts resin has high ability to resist corrosion
5.can be used according to the required to put aside the gear,
gear,layer board ,after spats ,fence ,mesh etc.
立柱满载承载能力根据***层横梁高度有所不同，***层横梁高度大于2米时，应在***层立柱处加背拉，
单排货架和墙之前加墙撑；立柱厚度1.5/1.8/2.0/2.5/3.0mm;当进深大于1200mm时可采用三立柱等结构形式。
Colum load bearing capacity according to first floor beam height is different ,the first layer when the beam is
greater than 2 m ,should increase pull back on the first floor pillar, single row between the shelf and wall and
wall bracket; Pillar thickness of 3.0mm /2.0/2.5;When the depth is greater than 1200 mm can adopt three pillar
structure,etc.
