AssetTrader Buying Guide to Cranes

Introduction

A crane is probably one of the most useful pieces of heavy engineering equipment used in construction. Essentially it is a lifting device that can be used to move items up down and horizontally. Cranes are mechanical lifting devices which use a winder, ropes and sheaves to lift or lower materials, as well as shifting them horizontally. They are commonly used in a number of sectors outside of construction, including the transport industry for the transportation of freight.

It is worth bearing in mind a number of factors before purchasing your crane. These include the types of task you will be utilizing the equipment for.

In practice the rated load (US) is a value less than that which would cause the crane to tip - normally 75% to tipping weight. For cranes supported by outriggers this is increased to 85%.
