March 2014 Showcase Webinar. Host: Mike Parnell, ITI Guest Speaker: Jim Jatho, Buckner Heavylift Cranes Crane Load Indicators are an essential crane operator aide. They allow the crane operator to monitor the weight they are lifting and help the operator avoid an overload incident. The Rayco/Wylie i4000 multi-purpose crane overload indicator uses the latest CAN bus technology and provides a wide range of optional configurations. A heavy crawler crane supports and manipulates the machine. It carries the power pack supplying the hydraulic power, which is conveyed through hoses to the three down-the-hole motors, two of them driving the cutter drums and the third driving the pump. Figure 4-9 Relationship of Bearing Capacity Factors to ø and N 4-9 (Standard Penetration Resistance) for Cohesionless Soils Figure 4-10 Slope Setback for Open Excavations/Trenches 4 -1 4 Figure 4-11 Effect of Surcharge Loads for Shored Excavations 4 -1 5 Figure 4-12 Setback Calculation for Shored Excavations when 4 -1 6 Plate Deflection and Stress. This calculation deals with the deflection, stress and variation of forces in the loaded flat plates. The calculation is designed for plates that are flat, homogeneous, with the same thickness and made from one material. Heavy lift studies consist of 2D and 3D simulations of the lifting scenarios, along with the corresponding calculations (e.g., lifting capacity checking, ground bearing pressure checking). These static simulations provide snapshots of mobile cranes at pick and set configurations, but they do not represent the movements between the two ...

The ground pressure under the outriggers is higher than it is under a crawler track because of the smaller bearing surface True An outrigger float should be approximately how much larger that the outrigger pad? used to produce a table of the crane and lift information, such as lifting capacity, ground bearing pressure calculations, and mat design. This application is supported by a database of specifications for various crawler cranes and configurations as well as capacity information. The application allows the user to input iii ABSTRACT Stability Assessment of Homogeneous Slopes Loaded with Mobile Tracked Cranes – An Artificial Neural Network Approach Xin Ai The assessment of stability of homogeneous slopes found as part of embankments, approach Importance of Ground Conditions: Adequate ground conditions are essential for safe crane operations because the crane’s capacity and stability depend on such conditions being present. If, for example, the ground is muddy or otherwise unstable, a crane could overturn even if operated with the load limits specified by the manufacturer. Oct 10, 2019 · 10. CRANE SAFETY HANDBOOK Toma Construction & Co.

Plate Bearing Test BS 1377 Part 9 : 1990 Standard. In the design of shallow foundation or traffic surface, design engineers need to know the bearing capacity of soil underneath. Plate bearing test is carried out in the field to serve this purpose. Results from the test can be used as design parameter or used to confirm the design assumption. Trump feels no pressure to be ...

Lifts with potentially unstable loads ( ie offset center of gravity, uneven lift points). Lifts using multiple cranes. Lifts over a defined percentage of crane capacity, often 75%. Lifts with difficult rigging arrangements. Sep 28, 2010 · If you would, step into the cab of our imaginary 65,000-pound crawler excavator and make a hypothetical lift. The site requires your machine to sit with its tracks parallel to the trench, but it's set back from the edge as far as practical for safety. This means you'll initially be picking an 8-foot length of 30-inch-diameter concrete pipe over the idler end of the machine. forces of the tower. The downward forces placed on the foundation are spread across its base such that the bearing pressure on the soils below are minimized. It is common for spread footer foundations to have one or more columns, or pedestals, protruding from the top of the slab to support the tower above at ground level. Engineering Spreadsheets - A huge collection A spreadsheet is a computer application that simulates a paper worksheet where becoming increasingly popular in solving engineering related problems. Among the strong features of spreadsheets are their instinctive cell-based structure and easy tuse capabilities. Excel, for example, the pressure under the tracks of the crawler crane (or the outriggers in the case of a hydraulic truck crane). Traditionally, this calculation is carried out according to a procedure where the weights of the crane-payload system components are assumed to be static forces that generate a pressure on the ground through the support layer usually in the form of mats, which are used to maintain an overall pressure that is below the ground bearing capacity. st≤ 2d = 500 mm Use say st,max= 350 mm Minimum area of a link leg: Asw,min (0.053 srst (fck)) /fyk= 0.053 x 175 x 350 x √30 / 500 ≥ 36 mm2. Use either H8s (50 mm2) and this would need 16 per perimeter or H10s (78.5 mm2) and 10 per perimeter. @ 350 mm tangential spacing and @175 mm radial spacing. Ground bearing forces Based on your machine model and specific lift requirements, calculate your crane's ground bearing reactions that are graphically illustrated in a 360° numerical presentation.
