• Guidelines for Inspecting Overhead Crane Structures

  This guide is intended to supplement the training and experience of personnel who are already qualified to perform structural inspections of overhead cranes. 1 The Crane, Hoist and Monorail Alliance, an OSHA Cooperative Program, Fact Sheet No. 1, Proper Inspection and

• The crane rail welding should follow the sequence of rail bottom, rail waist and rail head. Welding needs to be done layer by layer, and finally repair the surrounding gap. Preheating both ends of the track at the same time, preheating and interlayer temperature control between 300-350 degrees.

• Enclosed Arc (puddle arc) welding is widely used throughout the world for welding crane rails. Gantrail employ skilled technicians who can do this work or can train other operatives. In this method the two rail ends to be joined are cut square, placed about 20 mm apart, preheated and then welded using special manual metal arc electrodes.

• Dec 15, 2013 · Topic Welding Industry / Metallurgy / wear of rails – overhead crane – weld repair By Quibo Date 12-09-2013 12:34 Gents, I apreciate your suggestion regarding the pictures attached; we will try to repair the rails with a welding procedure according to AWS D15.2.

• wheels based on the capacity of the crane. The wheels ride along a crane rail which is supported by runway beams. The figure below illustrates the basic crane components; 1. Bridge – The Bridge is the principal structural component of an overhead crane. It spans the width of the building and comprises one or more load

• An overhead crane also known as bridge crane, overhead travelling crane, or industrial crane is a material handling machine which lifts, lowers, and transport a load horizontally. Typically, an overhead crane involves a hook-and-line mechanism that moves along a horizontal beam which moves on a runway beam, the supporting structure.

• for the Welding of Rails and Related Rail Components for Use by Rail Vehicles Supersedes ANSI/AWS D15.2-94 Prepared by AWS D15 Committee on Railroad Welding Under the Direction of AWS Technical Activities Committee Approved by AWS Board of Directors Abstract This document recommends minimum standards for the maintenance welding of rails and

• Design Guide for Overhead Cranes – Bright Hub Engineering

  The article describes the basic principles of operation of the Overhead cranes and the design selection criteria for the various components of the overhead crane. The major components of the Overhead crane are: a traveling base with a traveling rail on either side. Imagine the railway tracks; it is quite similar to the same except for the distance. The End carriage on both sides which houses

• ASME 830 STANDARDS COMMITTEE Safety Standard for Cableways, Cranes, Derricks, Hoists, Hooks, Jacks, and Slings (The following is the roster of the Committee at the time of approval of this Standard.)

• Overhead Cranes. Overhead cranes are used to aid in the building and repair of machines and materials, particularly within factories, and any well-outfitted fabrication shop will have them at their disposal. An overhead crane runs on rails attached to ceiling beams laid out as parallel runways. The moving section, known as the trolley, includes

• Crane rail have special rail, railway track, square rail and p-type rail, square rail wear to the wheel is relatively large, and now rarely used. Most of the crane trolley uses P type crane rail. Crane track selection as the following table: YWEHenan Dongqi Machinery Co., Ltd

• Types of Rail Welding Methods for Ordinary Rail and Crane Rails With the increasing speed of railway, more and more rails are connected by rail welding technology. Rail welding technology can be applied to ordinary rails, and can also be applied to high-speed seamless rails, special rails such as crane rails are also very suitable.

  In the process of welding the rail joints will be bent down, pre-use of copper and steel plate to the rail end pad from 40-60 mm, the use of a good bolt and pressure plate and other connectors to tighten the nut so that the rail fixed to the crane On the beam, there should be at least 4 fixed points near each rail joint.

• Crane Rail Welding/ET/09/14 • Railrod electrodes – 3.2mm for the foot and 5mm or 6mm for the remaining runs • Strip in foot of rail to suit rail • Copper mould for below the rail and for the two sides of the rail (to suit the section being welded) • Heat insulating blanket, to be used if required

• Our industrial overhead cranes represent high-level Konecranes quality starting from a single component all the way to an entire process. Chain hoist cranes With its robust design, smooth controls, and lifting capacity of up to 5 tons, the chain hoist crane is a strong link in your manufacturing process.

• 4. Rail joints at splices shall be ground smooth and level. The maximum gap between adjacent rail ends shall not exceed 1/16", except at switches or other free ends when 3/16" is permitted. 5. Hanger rods and superstructure rods are special steel and should never be welded or have welding connections applied to them.
