外 形 尺 寸 表 技 术 参 数 电缆卷筒概述 选型指南 1、弹簧式电缆卷筒适用于交流500V以下各种移动电器设备。2、线缆的卷取长度以安装方式图中的L为准，配备线缆长度分别为： （1）方式A为L+3圈。 （2）方式B为L+h+3圈（其中h值在订货时必须注明）。 （3）方式C、D中，为L+H+h+3圈。 （4）方式E、F，根据用户现场情况确定，订货时另行注明。3、方式C中卷筒固定在地面，收、放线缆时，线缆与地面存在相对摩擦，此时请在线缆运动轨迹范围内铺设滚道以减少线缆的摩损。4、方式F中一般取H=0.14L、h=0.5H，如果H<0.14L，h<0.5H，则定货时必须注明H、h值。5、电缆卷筒如需在单梁行车上与电动葫芦共同配用，可配给特制的滚轮支架部件，以便安装使用。6、卷筒上线缆的收、放方向在外形尺寸图中已标明。特殊要求，定货时必须注明。7、外形尺寸表中“质量”一栏，不包括线缆的质量。8、电动式卷筒结构形式以悬臂式为主（一般不标注）。9、特型卷筒、特殊用途产品请用户来人来函共同商议。 Guide for Pattern Selection 1. Spring type cable reel is designed for all kinds of electric appliance with 500V AC under.2. Drum length of cable is based on L in Installation Pattern Drw.The available cable lengths are:1）. L+3 loops for pattern A;2）. L+h+3 loops for pattern B （value h must be noted when ordered）;3）. L+H+h+3 loops for pattern C & Dl;4）. Pattern E and F confirmed per the customers" on-site conditions, specified separay when ordered;3. In pattern C, the reel is fixed on the ground. When coiling up or spooling off the cables, there appears relative friction between the cables and the ground. Thus, a rollaway nest should be mounted within the cable motion area to minimize wear-and-tear of the cable.4. In pattern F, generally H=0.14L, h=0.5H. If H is less than 0.14L, h>0.5H, the values H and h must be specified when ordered.5. Cable reel will be equipped with specially designed rolling wheel brackets for the convenience of installation if provided with electric block to run on the single bridge travelling crane.6. Cable reel coiling-up and spooling-off directions are marked in the overall dimension drawing. Make notes when ordered unless otherwise specified.7. The mass of the cable is excluded from Mass column in overall dimension table.8. The motor powered reel is generally of overhanging pattern in structure forms.9. Special sizes and special purposes of the products can be consulted or negotiated between the customers and the producer on meeting or in written letters.
