Purpose: To provide crane bridge beam sizes for Harrington's manual and powered chain hoists used in conjunction with Harrington end trucks. The Deflections Limits and Impact Factors are defaulted based on the Building Code. the beam including beam height, beam flange width, and beam flange thickness is important. Options: Shape. It’s possible you moved into a facility that previously had an overhead crane and the original support structure is still in place, and you’re adding a new crane, replacing an existing crane, or upgrading or modernizing a crane on an existing runway system. Scope: (a) Hoists – 1/8 to 10 Ton Capacities, US or Metric Tons. TO BUILD UNDERHUNG CRANE BRIDGES BRIDGE GIRDER SELECTION TABLE "S" BEAMS 12735 For proper runway size, consult qualified engineer or architect. ���{�{.

Top running overhead crane; It is the most common form of crane system which is … If the bridge is rigidly supported on two or more legs running on a fixed rail at ground level, the crane is called a gantry crane. This runway type is easily expandable, and can handle multiple bridge crane systems. You can match the size of the wheels to the size of the rails for proper alignment and tracking of the crane as it moves down the runway. You’ll want to make note of any cantilevers or haunches that the runway beam may be sitting on to determine how far off the building column the center line of the runway is. Crane beam design: Called often also a bridge crane, an overhead crane consists of parallel runways with a traveling bridge spanning the gap.The crane’s lifting component, known as the hoist, travels along the bridge. OSHA 1910.179(b)(6)(i) Overhead and Gantry Cranes states that, “a minimum clearance of 3” overhead and 2” laterally shall be provided and maintained between crane and obstructions in conformity with Crane Manufacturers of America, Inc., Specification No. �&��.�(٪�Ւ���P���g\z��tMc0�x,39Y M%Iǯi�ڋq p�o�^���POI��58;�s�U=gZ1��1?ǞN�"��+�]�$� �#t� �k��� Design of a Runway Girder Crane capacity = 50 tons (CMAA Class D) Bridge weight = 90.8 kips Trolley and hoist weight = 31.2 kips Wheel load = 78 kips (Maximum with lifted load) Wheel spacing = 11.0 ft.

Dearborn Overhead Crane … ... traveling beyond the center of either runway beam. �����>��ʗ��HQ�� &���F�v�> It is mandatory to procure user consent prior to running these cookies on your website. Usually, in hot dip galvanizing plants, these key elements are the distance between the rails – dictated by the building size – and the maximum weight to be lifted. Two cranes with an equal capacity and span could vary in price as much as $100,000 because high duty cycle cranes (Class D, E, or F) require specialized components like the hoist, end trucks, motor, bearings, and controls. It can travel at speeds as Span The span of a bridge crane refers to the distance between the center lines of the wheels at both ends of the main beam of the crane, that is, the distance between the center lines of the … While a crane manufacturer will come in to your facility and gather all of the information that they need to put a proper quote and specification together, it’s also a good idea for you as the consumer to be informed about the design and specification requirements for your new overhead crane. End trucks for wider flange beams or 3-1/4" patented track are available. If you’re able to get up close to the beam, you can measure the flange width, as well as the flange thickness. To do this, place your laser flush against a building support beam and measure down the length of the runway beam to the next support. If not, you can gather a lot of these measurements using your tape measure or your laser pointer. The better informed you are as a customer, the smoother the design, consultation, and quotation processes will be. Speed. ���d�}!��܉�|�E"�%��0�R In layman’s terms, this means that when you design your overhead crane system, you must consider any type of overhead obstructions including: You’ll need to know if your crane is a top running or under running design. During this step, you want to get measurements near the exact measurements to give the estimators and engineers enough information to put a quote together. The crane typically falls in two configurations, top running and under running system. Crane runway beam design aisc lrfd 2010 and asd esdep lecture note wg14 crane beam calculation structural ysis of overhead crane in simpson strong tie laboratory open access proceedings journal of physics conference. 1�) ���]�f|��'�����i���?3���%_(���� ���x9������ A top running crane runs on top of the runway beams and will be closer to any overhead obstructions, while an under running crane hangs off of the bottom flange of the runway beam. Consult our Crane Designer - an online tool that offers recommendations and helpful information, based on your specific lifting needs. These crane bridge kits contain all parts needed, except the bridge beam, cross shaft (when required), and the trolley stop angles to build under running, single girder crane bridges in rated loads and spans (center-to-center distance between runway beams) charted below. (b) Spans: 10 ft to 60 ft in 5 ft increments. The wheels ride on the rail rather than directly on the runway beam. In some instances, you may have existing runways in your building. For a Workstation Bridge Crane, the value is less (L/450) because the enclosed track is lighter. Beams Sized for US or Metric Tons. The model BCD4000 Crane Kit can be used to construct bridge cranes with up to 4000 pounds rated load. Selecting the right duty cycle or service classification of an overhead crane helps ensure that the components of the overhead crane are durable enough to withstand the load and usage requirements. You’ll then need to determine how close your crane will be to any of the obstructions mentioned above by measuring from the top of the crane to the bottom of any possible obstruction—ensuring the overhead gap is at least 3” and your crane runway beams and supports are at least 2” from any possible lateral obstruction. Runway CL to col CL distance left e L = [ ft ] 1.6 ft right e R = [ ft ] 1.6 ft Crane runway beam span - ver L 1-ver = [ ft ] beam span in ver direction, normally it's equal to building column spacing when there is no ver brace under runway beam This will determine the maximum height of your crane system. Getting measurements of the actual runway beam is as simple as running your tape measure from the bottom of the beam up to the top if you have easy access to the beam. Size. Small trolleys running on the c-track carry looped festoon conductors that provide power and control functions. GANTRY CRANE SPECIFICATION Overhead Cranes. Crane Runway Data - Beam Data (Revised: 05/09/2016) The Crane Runway Data - Crane Beam Data tab is used to define the Crane Beam, Channel, and Rail for this runway location. %PDF-1.6 %���� Wood Beam … Generally, this runway style typically uses ASCE Rail or square bar that is affixed to the top of a structural beam as a running surface for the top running crane. ����PE�8H\����%�КDF�o�S�z|ۊ Laser pointer – An inexpensive one can be found at hardware or home improvement stores for $65-70.

Bridge cranes can be divided into three grades according to the lifting weight: 5~10t small overhead crane, 10~50t medium overhead crane, and more than 50t heavy duty overhead crane. It’s also important to note the rail size if the overhead crane is top-running. Runway Length : Crane Type: Single Girder Top Running Double Girder Top Running Single Girder Underhung Double Girder Underhung Structure: Rail Size (If Top Running) Runway Beam Size (If Underhung) Bridge Travel: Motorized Push Geared If Motorized Single Speed Dual Speed VFD or Desired Speed If Geared Hand Chain Drop (Feet) Having a clear understanding of the space available in your building, the existing building supports that the crane can be installed on, and any overhead obstructions, will help you lay out the design criteria and expectations for any crane manufacturer who bids on the project.
