解析单梁起重机
Analytic single beam crane
单梁起重机作为物料搬运机械中最主要的一种，它具有一个桥架形承载结构的起重机，它依靠起升机构和在水平面内两个相互垂直方向作平移运动的运行结构，能在长方形空间内搬运货物。被广泛的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。
Single-girder crane as one of the most main material handling machinery, it has a bearing structure of crane bridge form, it relied on hoisting mechanism and two perpendicular direction in the plane of the running structure of translational motion, in a rectangular space can carry the goods. Is widely used in mechanical manufacturing workshop, metallurgy workshop, oil, petrochemicals, ports, railways, civil aviation, power station, paper making, building materials, electronics and other industries workshops, warehouses, yard, etc. It has the advantages of compact shape, low height, light weight and low wheel pressure.
单梁起重机根据结构可分桥式起重机、门式起重机、电动单梁起重机及悬挂起重机。根据主梁结构为桁架梁、箱型梁、蜂窝梁三种。
Single beam crane is based on the structure of bridge crane, portal crane, electric single beam crane and suspension crane. According to the structure of the main girder is trussed beam, box beam and honeycomb beam.
电动单梁主要型号有LDA型电动单梁起重机、LX型电动悬挂单梁起重机，CXT型单梁桥式起重机，MDG型单梁门式起重机，单梁抓斗起重机及欧式电动单梁起重机等。
Electric single-girder main models are the LDA type electric single-girder crane, LX type electric suspension single-beam crane, CXT type single girder crane, the MDGS type single-girder gantry crane, single beam grab crane and Europe type electric single-girder crane, etc.
单梁起重机主要技术参数
Main technical parameters of single beam crane
1起重量：是指起重机安全工作能容许的最大起吊货物的质量，它代表一台起重机吊载能力的大小。
Weight: this is the maximum lifting quality of the cargo which can be allowed by the crane safety work. It represents the size of a crane carrying capacity.
2跨度和悬臂伸距：轨道式单梁门式起重机的跨度是指起重机行走的轨道中心线的距离。悬臂伸距是指两侧轨道中心线分别至悬臂端吊具中心线之间的距离。
Span and cantilever pitch: the span of a single beam portal crane is the distance of the center line of a crane. The cantilever elongation is the distance between the center line of both sides of the orbit and the center line of the cantilever end.
3起升高度：吊具底部平面至地面的距离。
Lift height: the distance from the bottom plane to the ground.
4工作速度：单梁起重机结构工作速度根据作业要求而定。额定起升速度是起重机构电动机在额定转速或油泵输出额定流量时取物装置满载起升的速度。
Working speed: the construction speed of single beam crane is determined according to the requirements of the job. The rated rate of lifting is the speed of lifting when the motor is rated at the rated speed or pump output.
