商品详细描述

单梁起重机通常是指单梁桥式起重机,英文名Single-beam Crane。 单梁起重机桥架的主梁多采用工字型钢或钢型与钢板的组合截面。起重小车常为手拉葫芦、电动葫芦或用葫芦作为起升机构部件装配而成。
1.应用
广泛用于工厂、仓库、料场等不同场合吊运货物,禁止在易燃、易爆腐蚀性介质环境中使用。
设有地面和空中两种操作形式。地面操作有带线手柄操作和遥控器手柄操作两种;空中操作指司机室操作。司机室有开式、闭式两种,可根据实际情况分为左或右面安装两种形式,入门方向有侧面及端面两种,以满足用户在各种不同需要的情况下进行选择。
单梁桥式起重机广泛应用于机械制造车间、冶金车间、石油、石化、港口、铁路、民航、电站、造纸、建材、电子等行业的车间、仓库、料场等。具有外形尺寸紧凑、建筑净空高度低、自重轻、轮压小等优点。
2.型号
电动单梁主要型号有LDA型电动单梁起重机、LD型电动单梁起重机,LX型电动单梁悬挂起重机,

3.操作规程
工作前
a.带驾驶室的单梁桥式起重机、司机接班开车前,应对吊钩、钢丝绳和安全装置等部件按点检卡片的要求进行检查,发现异常情况,应予以排除。
b.地面操纵的单梁桥式起重机,每班应有专人负责按点检卡片的要求进行检查,发现异常情况,应予以排除。
c.操作者必须在确认走台或轨道上无人时,才可以闭合主电源。当电源断路器上加锁或有告示牌时,应由原有关人除掉后方可闭合主电源。
工作中
a.每班第一次起吊重物时(或负荷达到最大重量时),应 在吊离地面高度0.5米后,重新将重物放下,检查制动器性能,确认可靠后,再进行正常作业。
b.严格执行“十不吊”的制度:
①指挥信号不明或乱指挥不吊;
②超过额定起重量时不吊;
③吊具使用不合理或物件捆挂不牢不吊;
④吊物上有人或有其它浮放物品不吊;
⑤抱闸或其它制动安全装置失灵不吊;
⑥行车吊挂重物直接进行加工时不吊;
⑦歪拉斜挂不吊;
⑧具有爆炸性物件不吊;
⑨埋在地下物件不拔吊;
⑩带棱角块口物件、未垫好不吊;
c.发现异常,立即停机,切断电源,检查原因并及时排除。
工作后
a.将吊钩升高至一定高度,大车停靠在指定位置,控制器手柄置于“零”位;拉下刀闸,切断电源。
b.进行日常维护保养。
c.做好交接班工作。


Single girder crane usually refers to a single beam bridge crane, English name Single-beam Crane. Single girder crane girder by combined section I-shaped steel or steeland steel plate. Lifting trolley often hand chain hoist, electric hoist and hoist as lifting mechanism assembly.

1 Application

Widely used in factory, warehouse, yard and so on different occasions for lifting goods, prohibited the use of flammable, explosive and corrosive medium environment.

A ground and air two operation ways. The ground operation with line handle operationand remote control handle two; the air operation refers to the cab operation. The cabhas open, closed two, according to the actual situation can be divided in two ways of installation for left or right, the entry direction of side and end in two, in order to satisfy the users choice in different conditions.

Single beam bridge crane is widely used in mechanical manufacturing workshop,workshop, petroleum, petrochemical, metallurgical, power, railway, civil aviation port,paper, building materials, electronics and other industries workshop, warehouse, yard and so. Has the advantages of compact size, low building headroom, light weight,small wheel load etc..

The model 2

Electric single beam main models LDA electric single girder crane, LD type electric single beam crane, LX type electric single beam suspension crane,

3 operating rules

Before work

The driver single beam bridge crane, A. cab succession before driving, hook, wire rope and safety devices and other components inspection according to inspectioncard requirement, the abnormal situation, should be excluded.

Single beam bridge crane B. ground handling, each class should be responsible for inspection according to inspection card requirement, the abnormal situation, should be excluded.

The C. operator must confirm the catwalk or orbit unmanned, before closing the main power supply. When the power supply circuit breaker locking or sign, should take relevant people from the rear closing the main power supply.

Work

The A. class first lifting weights (or load reached the maximum weight), should be lifted from the ground height of 0.5 meters, the weight down again, check the brake performance, the confirmation of reliable, then normal operation.

B. strict implementation of the "ten not hanging" system:

The command signal is not unknown or arbitrary command;

Dont hang the rated lifting weight more than;

The sling used unreasonable or not in prison without hanging the hanging object bundle;

The hanging on someone or other floating objects are not;

The brake or other braking safety device failure;

Without lifting the vehicle weight hanging directly processing;

The slanting pull over not hanging;

The explosive objects without hanging;

The buried object does not pull the crane;

The angular piece of export objects, not pad is hanging;

C. found abnormal, immediately shut down, cut off the power supply, check andeliminate.

After work

A. will hook up to a certain height, car parked in the designated position, the controllerhandle at "zero" pull down the switch, cut off the power supply.

B. daily maintenance.

C. do shift work.
