詳細(xi)介紹：

　　1.選取和安裝

　　叉車配重的(de)(de)(de)質(zhi)(zhi)(zhi)量(liang)(liang)、質(zhi)(zhi)(zhi)心位(wei)置、后(hou)懸(xuan)量(liang)(liang)由整車(che)總體布置給定(ding)(ding)(ding)，其(qi)中平衡(heng)(heng)重(zhong)(zhong)(zhong)質(zhi)(zhi)(zhi)量(liang)(liang)的(de)(de)(de)選取主(zhu)要考慮叉車(che)滿(man)(man)載堆垛和滿(man)(man)載行駛時的(de)(de)(de)縱向穩(wen)定(ding)(ding)(ding)性。平衡(heng)(heng)重(zhong)(zhong)(zhong)的(de)(de)(de)質(zhi)(zhi)(zhi)量(liang)(liang)直接(jie)影響(xiang)到叉車(che)前、后(hou)平衡(heng)(heng)的(de)(de)(de)保護系(xi)數，是決定(ding)(ding)(ding)叉車(che)保護系(xi)數的(de)(de)(de)主(zhu)要參數。當平衡(heng)(heng)重(zhong)(zhong)(zhong)的(de)(de)(de)總質(zhi)(zhi)(zhi)量(liang)(liang)G定(ding)(ding)(ding)下來(lai)后(hou)，即以后(hou)橋為基準，根據車(che)架(jia)(jia)上平衡(heng)(heng)重(zhong)(zhong)(zhong)的(de)(de)(de)裝(zhuang)配形(xing)(xing)式，準確(que)明確(que)平衡(heng)(heng)重(zhong)(zhong)(zhong)的(de)(de)(de)安裝(zhuang)尺寸。叉車(che)尾(wei)架(jia)(jia)上部外側有2個倒置的(de)(de)(de)V形(xing)(xing)懸(xuan)掛(gua)塊，將平衡(heng)(heng)重(zhong)(zhong)(zhong)用2條(tiao)螺栓固定(ding)(ding)(ding)在其(qi)上。

　　2.通風孔

　　由于(yu)熱(re)平衡(heng)是叉車(che)(che)很(hen)重(zhong)(zhong)要的參數，散(san)熱(re)性能(neng)不好很(hen)容易造成發動(dong)機冷卻水(shui)水(shui)溫過高(gao)現象，影(ying)響(xiang)叉車(che)(che)整車(che)(che)性能(neng)。因此，平衡(heng)重(zhong)(zhong)通風(feng)孔的位(wei)置、風(feng)道與氣流導向就顯得很(hen)重(zhong)(zhong)要。通風(feng)孔開的越高(gao)越大(da)越利于(yu)散(san)熱(re);通風(feng)孔到散(san)熱(re)器之間采用圓角過渡，以(yi)利于(yu)氣流導向，提散(san)熱(re)性能(neng)。

　　3.離去角

　　配重(zhong)(zhong)下端(duan)的離(li)去角也(ye)很(hen)重(zhong)(zhong)要，該角度主要是為了分(fen)開上、下坡時平衡(heng)重(zhong)(zhong)下端(duan)與地面摩擦，理論上離(li)去角與具體車型的大(da)爬(pa)坡角相等。平衡(heng)重(zhong)(zhong)下端(duan)切除點的位(wei)置要根據(ju)具體車型的大(da)爬(pa)坡度、平衡(heng)重(zhong)(zhong)的后懸量來明確。
