摘要

摇臂式行车又称立柱式摇臂起重机，起重量在125千克至5000千克，是由电葫芦、摇臂驱动装置、摇臂和立柱构成。立柱下面底座由地脚螺栓安定在混泥土上，由电机带动减速驱动装置使摇臂回转，电动葫芦在工字钢上作直线往复运动作业。它的特点有：自重轻、梁长、起重量大，安装、操作、维修方便。它们完全独立，是一种很好的工作岗位起重机，并适用于各种场合的货场和装卸平台。立柱占地面积小。对于提升空间非常小的情况下也可以获得相当大的起重高度。

关键词:摇臂式、立柱式、起重机

Abstract

Rocker driving is also called the pillar jib crane lifting Weight in 125Kg-5000Kg, is composed of an upright column rocker arm-rocker driving device and electric hoist components.
The column is the base through the bolt and set in concrete foundation driven by a motor reducer drive the rocker arms, electric hoist for movement operation in the spiral arms i-steel .It’s features are light weight, arm length, weight, installation, operation ,repair simple .They are complete lying dependent, is an ideal job crane, yard and loading and unloading platform and is suitable for outdoor. The column has the advantages of small Rocker driving is also called the pillar jib crane, lifting weight in 125Kg-5000Kg, is composed of an upright column, rocker arm, rocker driving device and electric hoist movement operation in the spiral arms i-steel. Its features are: lightweight, arm length, weight, installation, operation, repair simple. They are completely independent, is an ideal job crane, yard and loading and unloading platform and is suitable for outdoor. The column has the advantages of small circumstances can also get great lifting height.

Key words : rocker arm type, column type, crane
