1. Product introduction

1.1综述

1.1 General description

LD-A型电动单梁起重机（以下简称起重机）是按JB/T1306标准设计制造的，与CD1、MD1等形式的电动葫芦配套使用，成为一种有运行轨道的轻型起重设备。其额定载荷1t-10t；跨度7.5m~22.5m，适用温度-25℃~+40℃，湿度≤85%，无火灾、爆炸危险和腐蚀性介质的环境中工作，禁止吊运熔化金属，有毒、易燃、易爆物品。

The LD-A Motor Single-Track Crane (hereafter referred as the crane) is designed and manufactured according to the JB/T1306 standard. Operated with electric hoists of CD1 and MD1, it is a railed light crane. Its rated load is 1t-10t; the span is 7.5m-22.5m; range of working temperature is -25℃- +40℃; the humidity is ≤85%. The crane is not suitable to be used in environment with the danger of fire and explosion and corrosive media. Hoisting melted metal and toxic, flammable and explosive substances is prohibited.

为方便用户，设有地面和操纵室两种操纵形式，操纵室又设有端面及侧面开门两种形式，供用户选择使用。

To meet the customer’s need, the crane has two operation modes of ground operation and operater cab operation. The operater cab has two types of top-open and side-door open for the customers to choose from.

本产品广泛用于机械制造、装配、仓库等场所。

The crane can be used widely in machinery manufacture, assembly and storehouse. 1.2结构特点

1.2 Structural features 1.2.1金属结构部分 1.2.1 Metallic structure

主梁采用钢板焊接梁与工字钢的组焊结构，横梁也是用钢板组焊成箱形横梁，为贮运方便，主、横梁之间用高强度螺栓连接。

The main girder is welded structure of beam welded by steel plate and I-iron. The cross beam is also box beam welded with steel plates. For the convenience of storage and transportation, the main girder and the cross beam is connected with high-strength bolt.
