重慶升降機一般都在顯著的位置標(biāo)明貨梯的額定載重量，但都不設(shè)超載保護自動控制系統(tǒng)。現(xiàn)在通過在貨梯電控系統(tǒng)中加裝超載保護的智能控制，對消除貨梯操作人員違章行為，規(guī)范使用貨梯的生產(chǎn)作業(yè)人員的行為習(xí)慣，以及預(yù)防誤操作，都具有較好的實用價值。
Zhejiang freight elevators are generally marked with a prominent position in the freight elevator of the rated load, but not set in Zhejiang Huoti overload protection automatic control system. Now through the installation of overload protection intelligent control electronic control system in the freight elevator, freight elevator operator to eliminate violations of Zhejiang, regulate the use of the freight elevator of the production staff of behavior, as well as the prevention of misuse, has good practical value.

重量超載檢測的安裝根據(jù)貨梯原有的構(gòu)造情況，在升降貨梯機房固定轎廂側(cè)的綱絲繩頭處，加裝一壓力傳傳感器，在這里加裝傳感器對感應(yīng)貨梯吊廂的重量最直接，安裝也較方便，只要再多做一塊附加繩頭板即可。由于貨梯吊廂的鋼絲牽引方式是吊廂一端鋼絲繩固定電梯機房的橫梁上，另一端經(jīng)過吊廂頂輪過渡到主機曳引輪上，鋼絲繩從主機曳引輪再經(jīng)貨梯配重塊的繩輪回到貨梯機房的橫梁上固定的。貨梯的吊廂就是掛在滑動輪上的廂體，其吊廂一端鋼絲繩固定橫梁上所承受的拉力為吊廂總重量的一半，因此，傳感器的曳引比為2：1的。
Weight overload detection installation according to the original structure of the freight elevator, the room in cargo lifter fixed rope car side of the Gang head office, the installation of a pressure sensor pass, where the installation of the sensor for sensing the weight of the freight elevator gondolas of the most direct, installation is relatively easy, as long as the more you can do an additional rope board. Because Zhejiang freight elevator gondolas wire traction is on one end of the rope fixed gondolas elevator machine room beams, and the other end through the top of the wheel gondolas transition to the host traction sheave, rope sheave from the host and then the weight of the freight elevator with a rope transmigration to the freight elevator machine room beams fixed. Zhejiang freight elevator of gondolas that hung on a sliding wheel envelope, gondolas on its end of the rope tension of fixed beams gondolas for half of the total weight, therefore,traction sensors ratio of 2: 1.

在實際應(yīng)用時，為消除貨梯在運行中的自重變化，在重量超載檢測系統(tǒng)投入運行前，將浙江貨梯作上、下運行一遍，分別將每一層站的向上和向下的重量記錄到控制器的寄存器中，以便從寄存器中讀出吊廂在當(dāng)前層站的數(shù)據(jù)，自動去除吊廂的自重，以檢測吊廂內(nèi)的凈重量。重量超載控制要求貨梯的載重量達到額定載重量的95％時，貨梯只能直駛某一個指定的向上（或向下）樓層。貨梯的載重量達到額定載重量的100％時，貨梯超載將自動報警，此時貨梯門不能關(guān)閉，貨梯不能啟動。
Before the actual application for the elimination of weight change in the operation of the freight elevator in weight overload detection system put into operation, will make Zhejiang freight elevators, running again, up and down, respectively, the weight of each layer of the record to the control station the register to be read from the register gondolas in the current landing data automatically remove the gondolas of weight, net weight detection gondolas inside. When the weight of the load freight elevator overload control requirements up to 95% of rated load, freight only one designated straight ahead up (or down) floor. When the freight elevator to reach 100% of rated load carrying capacity, freight overload will automatically alarm, when the freight elevator door can not be closed, freight not start.

升降機重量一旦超重，貨梯的應(yīng)急啟動系統(tǒng)也被終止；貨梯消防直駛功能被終止；遇到停電時的貨梯緊急停靠功能不能投入工作。貨梯重量一旦超重，退出貨梯的物料的載重量必須使貨梯額定載重量的95％以下時，貨梯的超載報警及鎖定裝置才會自動復(fù)位。若升降貨梯要做超載試驗時，可通過一個指令開關(guān)來關(guān)閉超載保護功能，方便地將超載保護系統(tǒng)退出貨梯控制系統(tǒng)。
Zhejiang weight once overweight freight elevators, freight elevators emergency start system has also been terminated; Huoti the fire straight ahead function is terminated; Huoti emergency stop function during a power cut can not be put to work. Huoti weight once overweight, quit freight elevator load the material must be 95% of rated load freight elevator below, freight overload alarm and locking device will automatically reset. If cargo lifter overload test done, you can switch to turn off overload protection through an instruction, easily overload protection system exits the freight elevator control system.
