Bearing capacity of soils for crawler cranes
Canadian Geotechnical Journal, 2008Few studies have been carried out on the bearing capacity of soils for crawler cranes. Directly applying the bearing capacity equations used for shallow foundations to cranes often leads to conservative design. The total settlement is of less concern for cranes than for buildings, and cranes can normally tolerate larger differential settlements ...

A Search Strategy for Motion Planning of Unmanned Crawler Crane
2019 7th International Conference on Control, Mechatronics and Automation (ICCMA), 2019The motion planning for unmanned crawler crane (UCC) whose initial and goal described accurately in workspace was challenging. The difficulty dues to the fact that the initial and goal produce low-dimensional self-motion manifolds, which rendered the search of planners bypassing the self-motion manifolds.

Study and Implementation of a Cooperative Hoisting for Two Crawler Cranes
Journal of Intelligent & Robotic Systems, 2015Dual-crane cooperative hoisting is necessary for heavy loads and certain equipment in petrochemical plants, but most dual-crane hoisting are carried out by two drivers commanded under one or more banksmen, thus leading to low hoisting efficiency and bad hoisting quality.

Level luffing control system for crawler cranes
Automation in Construction, 2004A level luffing control system for crawler cranes has been developed. By using this system, an operator can safely keep suspended loads level at elevated spots or on sites where visual operation is impossible. This system consists of a microcomputer-based controller, sensors (boom angle, rope length, boom lever pressure, engine speed) and hydraulic ...

Crawler Cranes Modeling Method Based on OGRE
Advanced Materials Research, 2010According to the crawler crane’s structure and the scene management principle of OGRE (Object-Oriented Graphics Rendering Engine), this paper presents a new 3D parameterized modeling method of crawler cranes. By integrating the interactive modeling using 3DSMAX and the geometrical graphics modeling, the new method can solve the problem about rendering ...

Path Planning for Crawler Crane Using RRT*
2012Lift path planning is a key subtask in preparing lift plan. Many researchers have concerned the topic of automated path planning for crane lifts. Previous studies provided some exact approaches or optimization methods to solve the problem. However, these approaches failed when they handle the problem with high DOFs.

Design and Realization of Crawler Crane’s Lifting Simulation System
Volume 3: 28th Computers and Information in Engineering Conference, Parts A and B, 2008Most construction projects rely on crawler cranes to perform lifting and hoisting activities. In practice, crawler cranes are managed based on demand, urgency, and prioritized work tasks that must be performed within a set period of time in the field. A lifting plan is needed to make.
