与有砟轨道的干扰电压进行对比分析的结果表明：无砟轨道钢筋网络在一定程度上增大了钢轨回流在牵引回流中的比例，使得牵引电流对轨道电路的干扰电压略有增大。

The machine has the advantages of big conveying capacity, high hoisting height, stable and reliable running and long working life. Its performance and parameter accord with JB3926—85 'Vertical Bucket Elevator', which consults the international standard and advanced foreign standard and the towing circle chain accords with MT36—80 'High-Strength Circle Chain for Mine'. The machine is applicable for conveying the power, grain and block materials, such as coal, cement, block, sand, clay and ore. The bucket elevator is allowed to convey materials with high temperature with the special circle chain structure.

该类提升设备具有输送量大，提升高度高，运行平稳可靠，寿命长显著优点，其主要性能及参数符合JB3926——85《垂直斗式提升机》（该标准等效参照了国际标准和国外先进标准），牵引圆环链符合MT36——80《矿用高强度圆环链》，本提升机适于输送粉状，粒状及小块状的无磨琢性及磨琢性小的物料，如：煤、水泥、石块、砂、粘土、矿石等，由于提升机的牵引机构是环行链条，因此允许输送温度较高的材料。
