上海融瑞环?？萍加邢薰疚挥诠式鹑谥行?-中国上海。公司是吊钩可视化、塔吊黑匣子、扬尘监测系统、塔吊监测系统、雾炮、塔机喷淋、工程洗轮机、指纹锁、人脸识别、风速仪等一系列环保设备的研发生产销售为一体的专业化公司，同时还与美国，日本有着技术合作，深厚的外资背景使公司获得了坚实的技术支持和雄厚的资金实力。<br>该产品广泛适用于0-10T各种施工升降机、龙门吊、电动葫芦、卷扬机，塞入式传感器测量的起重机械。升降机载荷量达到相应限制重量时，限制器声光报警；控制仪可以输出两组继电器输出触点信号，分别实现静态超载报警、动态极限报警。当重量达到限制重量时，输出继电器触点信号，切断电路，使升降机不能启动运行。一．适用范围及功能概述：轴销式安装（轴销式传感器安装在导轨托架与吊笼吊耳连接轴处）。三．主要特点：．限制器采用两段3位数码管显示；分别显示额定载荷值及实时载荷值，并于调试状态显示调试信息。2．克服升降机启动时的惯性误报警。4．具有故障自诊断功能，当系统故障或断电时输出超载信号。．传感器结构紧凑，安装方便。四．技术指标<br><img

style="margin: auto;clear: both;display: block" src="http://l.b2b168.com/2019/08/07/00/201908070026245023284.jpg" alt="大同电梯超载?；て鞒Ъ?/><br>随着国内建筑行业的崛起，越来越多的高楼大厦出现在人们的视线里。随之而来的，在施工现场出现的问题也越来越多。施工现场的升降机不能长时间，满负荷的工作，如果这样就会造成坠梯的危险，造成人员的伤亡，财产的损失，所以为了确保施工现场的安全，减少损失，就必须安装必要的设备来显示升降机里的重量，一旦超载必须报警。这种称重装置就具备这样的功能。<br>产品特点：<br>1、装置采用三位数码管，正常工作状态用于显示升降机当前实际重量，调试状态用于显示升降机仪器设置信息，方便用户操作。<br>2、可按要求进行触电输出，以实现控制升降机运行。<br>3、由于不同高度的重量的显示值是不同的，该装置可以通过自我学习功能将重量不管在什么位置都能显示相同值。<br>4、它运用轴销式传感器，而且备有多款传感器，可以根据用户需要自由选择。<br>5、装置采用对升降机启动瞬间进行采样延时处理，保证在升降机启动瞬间不会因为惯性原因导致误报警。<br>6、控制仪具有故障自诊断功能，当系统故障或断电时输出超载信号。<br>7、控制仪具有数据锁定功能，非设备管理人员不能改变仪器内参数，**施工升降机安全运行。性能参数电源 AC 220（-15～+10%）V 精度 1.0级灵敏度＜0.1 % 控制回差＜1 % 工作温度－10 ～ 60℃ 仪器功耗＜10W 传感器过载能力 150 % 输出触点容量 2A/DC24V； 2A/AC220V 外型尺寸 108×128×68mm 该产品性能优越，使用方便，价格合理，是安全施工的产品。<br><img style="margin: auto;clear:

alt="大同电梯超载?；て鞒Ъ?/><br>超载保护装置的种类<br>电梯的超载?；ぷ爸眯褪讲煌?，装设位置也不同，常见的超载装置有以下几种形式。<br>(1)活动轿厢<br>这种超载?；ぷ爸糜τ梅浅９惴?，价格低，安全可靠，但更换维修较繁琐。<br>通常采用橡胶垫作为称重元件，将这些橡胶元件固定在轿厢底盘与轿厢架固定底盘之间。<br>当轿厢超载时，轿厢底盘受到载重的压力向下运动使胶垫变形，触动微动开关，切断电梯相应的控制功能。一般设置有两个微动开关，一个微动开关在电梯达到80%负载时动作，电梯确认为满载运行，电梯只响应轿厢内的呼叫，直到驶至呼叫站点(满载直驶);另一个微动开关在电梯达到110%载重量时发生动作，电梯确认为超载，电梯停止运行，保持开门，并给出警示信号(超载?；?。微动开关通过螺栓固定在活动轿厢底盘上，调节螺栓就可以调节载重量的控制范围。<br>(2)活动轿厢地板<br>这是装在轿厢上的超载装置，活动地板四周与轿壁之间的保持一定间隙，轿厢地板支撑在称重装置上，随着轿厢地板承受载荷的不同，地板会微微的上下移动。当电梯超载时，活动轿厢地板会下陷，将开关接通，给出电梯的控制信号。<br>(3)轿顶称量装置<br>这种装置是以压缩弹簧组作为称重元件，在轿厢架上梁的绳头组合处设以超载装置的杠杆，当电梯承受不同载荷时，绳头组合会带动超载装置的杠杆发生上下摆动。当轿厢超载时，杠杆的摆动会触动微动开关，给电梯相应的控制信号。<br>(4)杋房称量装置<br>当轿底和轿顶都不方便安装超载装置时，电梯采用2：1绕法时，我们可以将超载装置装设在机房中。它的结构和原理与轿顶称量装置类似，将它安装在机房的绳头板上，利用机房绳头板随着电梯载荷的不同产生的上下摆动，带动称量装置杠杆的上下摆动。<br>(5)电阻应变式称量装置<br>以上各种称量装置输出信号均为开关量，随着电梯技术的不断发展，特别是电梯群控技术的发展，客观上要求电梯的控制系统精确的了解每台电梯的载荷量，才能使电梯的调度运行达到状态。因此传统的开关量载荷信号已经不再适用于群控技术，现在很多电梯采用电阻应变式称量装置。<br>公司精益求精，满足用户需要，质优价廉，供应可靠产品，真诚相待”是我们的服务宗旨；“用质量信誉去开拓市场，用品种去满足顾客需求，用持续改革提升顾客满意度”提供优良服务是我们的质量方针。<br
