Real-time Obstacles Avoidance for Crawler Crane based on DQN

2021 The 13th International Conference on Computer Modeling and Simulation, 2021
Safety always is a crucial consideration for crawler cranes running with dozens of tons of load in its work site. However, around its work site, besides static obstacles, there are many dynamic obstacles, such as workers and engineering vehicles. These obstacles are potential risk for crane in congested work site.

Bearing capacity of soils for crawler cranes

Canadian Geotechnical Journal, 2008
Few 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), 2019
The 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, 2015
Dual-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.

Path Planning for Crawler Crane Using RRT*

2012
Lift 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.

Level luffing control system for crawler cranes

Automation in Construction, 2004
A 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, 2010
According 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 ...

Design and Realization of Crawler Crane’s Lifting Simulation System

Volume 3: 28th Computers and Information in Engineering Conference, Parts A and B, 2008
Most 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.
