The present invention relates to a container for transport and storage of excavator attachments. In particular, but not exclusively, the present invention relates to a container for securing excavator attachments on a trailer. A container for retaining an excavator attachment on a trailer comprises a lower portion including a base, a pair of opposing end walls, and a front wall; a lid connected to the lower portion and arranged to pivot between a first position, in which the container may receive an excavator attachment, and a second position, in which the excavator attachment is retained by the container; and a coupling configured to secure the container to a trailer such that the end walls of the lower portion are adjacent side walls of the trailer and the front wall of the lower portion is adjacent a front wall of the trailer, wherein a depth of the lid, in a direction perpendicular to the base of the container, is greater than a depth of the lower portion.

The angle of a trailer with respect to a tow vehicle is an important parameter to the stability of the vehicle and trailer. A tow vehicle pulling a trailer in a straight line is generally more stable than when the vehicle is turning. While turning, the angle between the tow vehicle and the trailer is not a straight line but is another angle depending on how sharply the tow vehicle is turning. To safely operate a vehicle towing a trailer, for a given steering input and speed, there is a maximum angle between the tow vehicle and trailer whereby exceeding the angle causes instability and may cause the trailer or tow vehicle to roll over or jackknife. Accordingly, the angle between the trailer and tow vehicle must be determined to ensure the vehicle and trailer will continue to be in control.

A portable industrial heater including a housing having an air inlet and an air outlet, one or more burners housed within the housing and configured to heat air passing through the housing from the air inlet to the air outlet, and a generator selectively providing power to the one or more burners. The air inlet and the air outlet are positioned on a same side of the housing.
