optimal design of welded i-beam of slewing

2016-12-16low headroom offers optimal highest hook position optional electric slewing gear optional electric hoist travel optional mobile control The illustration shows a crane with electric slewing gear electric trolley travel and mobile control ABUS VS pillar jib crane with electric wire rope hoist low headroom offers optimal highest hook position The optimal design scheme is when the wall thickness of the arm is 4 mm and the wall thickness of the crossbar is 3 mm this paper designed a new type of in-situ slewing device and conducted a finite element simulation analysis on it On this basis by combining the optimization theory this paper further optimized the structure of in-situ

Sensors

Of all the machinery and equipment used on construction sites excavators are responsible for the greatest number of fatal accidents Excavation is an inherently risky process due to imprecise work processes and the unstable external environment on most work sites The resulting accidents cause serious injuries that threaten the lives of not only the excavator pilots but also those working

The twin slewing bearing has an 8-point contact zone ball-raceway which is considered in a cross section of bearing rings Characteristic features of these bearings have been described The main thesis of this work concerns the adaptation of modern computer methods for solving the structural design problems of twin slewing bearing

Does a pier have to be round?

2012-3-18A large I-beam isn't the most optimal but you aren't trying to support a load at low factor of safety you should be eclipising the load with something much stronger than what is needed In this case an I-beam say 8 deep had nice open slots on the sides where you can mount electrical boxes and such where they are protected

Abstract: After being able to determine the structural behavior by means of finite methods (e g finite elements finite differences boundary elements) an important goal of engineering activities is to improve and to optimize technical designs structural assemblies and components The task of vector or multicriteria structural optimization is to support the engineer in finding the best

Frame extension is secured to the beam with bolts To secure a load on the trailer the frame has welded on sling loops/anchor points for the tensioning belt The trailer features original crane base gate design as well as easy-climbing bogie construction with the ability to adjust the longitudinal position for optimal

Projects are presented at the beginning of the term teams are formed and for the next twelve weeks teams follow a structured design process that culminates in a proof-of-concept prototype Projects identified to have a significant impact a committed team and a viable market can be continued into the spring term for the next level implementation

Present design today has a bolted connection between the slewing house and the stabilizer beam The purpose of this study is to form a new design of a slewing house optimized for a welded connection to the stabilizer beam The new design is compared to present design in terms of weight and cost

Ace Crane will provide higher duty cranes with hoist ropes and drums specifically designed for magnet use For handling longer loads with multiple magnets fitted under a spreader beam the cranes may require a twin hook arrangement and a slewing mechanism on the hoist trolley as an additional feature to suit the process requirements
