The economical light weight crane mat assembly can comprise a frame assembly with a main load-supporting bar, crossbars and perimeter bars. The special crane mat carrier can be easily connected to a crane, such as with a drawbar fixture, securing plate and locking plate. A hanger assembly with a suspension bar can be provided to hang the crane mat carrier. A latch mechanism can also be provided to securely lock the crane mat carrier. | 08-22-2013 |
20140116975 | OUTRIGGER PAD MONITORING SYSTEM - An outrigger pad monitoring system for determining crane stability includes a plurality of outriggers having sensors for measuring a load placed on the outriggers. A crane control system utilizes the measured load on the outriggers to determine the stability of the crane. A crane control system utilizes the measured load on the outriggers with positional information for the crane boom to determine if the crane boom is in a side-load condition. The outrigger pad monitoring system may be used during the setup of the crane and to verify the proper operation of a rated capacity limiter. | 05-01-2014 |
20140332488 | Crane Access Staircase and Mounting System - An access system for facilitating access to an elevated deck of a mobile crane includes a staircase having a support post defining an axis of inclination. A plurality of ascending steps is connected to the at least one support post, and a mounting bracket is pivotally coupled to an upper end of the at least one support post. The staircase is pivotable about a longitudinal axis such that a lower end of the at least one support post is induced to move in a lateral direction in response to pivotal motion of the at least one support post. A caster is coupled to the lower end of the support post for supporting the staircase on a ground surface. The caster supports the staircase on the ground surface throughout longitudinal movements of the staircase and lateral movements of the staircase induced by vertical movements of the mobile crane. | 11-13-2014 |
