Lift path planning for a nonholonomic crawler crane
Automation in Construction, 2014Abstract This paper presents an efficient lift path planning approach for a crawler crane in which the mobility of the crawler crane and its nonholonomic kinematics are considered. To obtain the optimal path rapidly, we improved the bidirectional Rapidly exploring Random Trees (RRTs) using a sampling strategy and an expansion strategy.

Reliability-based design optimization for the lattice boom of crawler crane
Structures, 2021Abstract The reliability-based design optimization (RBDO) problem involving discrete design variables and multi-working constraints is tackled with the consideration of the uncertainty factors in the optimal design of crawler crane’s lattice boom. In the optimization model, the uncertainties of material property, geometric parameters and loads are ...

Stress distribution under crawler crane timber mats
, 2019 In the construction industry, it is common practice to use timber mats beneath crawler cranes to redistribute heavy loads over large surfaces and allow the stresses on the soil to fall within allowable design limits. The distribution of stresses beneath the mats is generally assumed to be uniform, which implies that the crawler and mats are regarded ...

Real-time Obstacles Avoidance for Crawler Crane based on DQN
2021 The 13th International Conference on Computer Modeling and Simulation, 2021Safety 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.
