Systems and methods for a mobile crane are provided. In particular, systems and methods are provided for a mobile crane that is designed to enable easy transportation on a railcar to and from a job site. The mobile crane facilitates quick changing between a transport configuration and a work configuration to enable increased productivity. The mobile crane is configured to be modular and thereby be configured to include various lifting and object manipulating features, as required by a specific application.

The present invention provides a lid (400) for an open container (100, 13.10), a lid lifting system (13.100), a tippler (13.200) with the improved lid lifting system (13.100) and a method of lifting a container. The lid and lifting arrangement includes an apertured receiving formation (401) on an upper side of a lid (100) to receive a lift member (13.40). The lift member (13.40) can do one or more than one of the following: engaging the formation (401) will unlock a locking mechanism (13.42,458) holding the lid (400) to a container (100); or allow the lift member (13.40) to be rotated to thereby unlock the locking mechanism (13.42, 458) which locks the lid (400) to the container (100), while simultaneously locking the lift member (13.40, 458) to the lid (400). A lifting device which is able to perform such actions is also disclosed, and a method to operate the lifting device.

A payload coupling apparatus is provided that includes a housing having an upper portion, a lower portion, and a side wall positioned between the upper and lower portions, an attachment point on the housing adapted for attachment to a first end of a tether, a slot in the housing that extends downwardly towards a center of the housing thereby forming a hook or lip on the lower portion of the housing beneath the slot, a plurality of holes in the upper portion of the housing; and a plurality of holes in the lower portion of the housing. A method of retracting a payload coupling apparatus during UAV flight is also provided.
