A rope connector connects prepared ends of two rope segments, wherein said prepared ends each include a rope eye. The rope connector includes at least two complementary parts, each being configured with a shaped recess for receiving at least part of said prepared end of a respective rope segment. The complementary parts are detachably mountable to each other to establish a firm connection there between. A rope extension system is disclosed to include such rope connector, and a hoisting system employs such rope extension system.

A lift unit docking system includes a docking rail, a docking rail adapter, and a locking mechanism. The docking rail is configured to provide ingress and egress of a lift unit to and from an overhead rail, and includes a body defining a channel and an adapter receiving opening within the body. The docking rail adapter is repositionable relative to the adapter receiving opening of the docking rail and is configured to transport the lift unit into and out of the channel of the docking rail. The locking mechanism is repositionable between a locked position and an unlocked position, wherein the locking mechanism extends into the channel to block movement of a mounted lift unit toward the adapter receiving opening of the docking rail when in the locked position.

Provided is a crane that can detect obstacles within a sufficient range while traveling and while doing work. A crane that is provided with an obstacle sensor that, during travel, detects the approach of obstacles toward a front side part of a travel body and, during work, detects the approach of obstacles toward a rear side part of a turning body. According to a first embodiment, the obstacle sensor has a detection range that is directed from front to rear. According to a second embodiment, the obstacle sensor has a detection range that is directed from rear to front.

Disclosed is a base assembly for supporting a crane pedestal. The base assembly comprises four base units, each having a first end and a second end, and each base unit being of an L-shape with an outside beveled corner. Fastening devices connect each base unit at their first and second end to respective first and second ends of another of the four base units. The four base units are dimensioned so that, when connected by said fastening devices, they form an octagonal-shaped base structure. The four base units are also dimensioned to support four pads that each rest on a face of each unit adjacent to its beveled corner when the four base units are assembled in the octagonal-shaped base structure. Also disclosed is a method for assembling a base assembly for supporting a crane pedestal and a fastening device for connecting the ends of two units together.

A rough terrain crane is equipped with dashboard cameras and digital cameras for capturing bird's-eye view image thereof. The equipment performs, when a load factor reaching 90%, a process of recording start for starting image data recording with the digital camera and a process of storing measurement value for recording a load factor concurrently with the process of recording start. The image data is recorded with the digital camera associated with the above activation condition, among the digital cameras installed in the rough terrain crane.
