Abstract: Depth detector assemblies for material handling attachments are disclosed. In some embodiments, the depth detector assemblies may include at least one ultrasonic sensor removably attached to the material handling attachment. The depth detector assemblies may additionally include a controller removably attached to the material handling attachment and capable of receiving signals from the at least one ultrasonic sensor. The depth detector assemblies may further include a light display capable of being selectively illuminated by the controller to indicate depth of a load relative to the material handling attachment based on the received signals from the at least one ultrasonic sensor.

Abstract: A load handler is capable of loading and unloading tall unitary resilient loads such as large construction tires or other tall compressible loads such as bales normally considered incompatible for shipment in standard closed-top containers, to enable such compatibility economically. The load handler has a pair of vertically spaced load clamping arms, the upper arm being capable of rotating such a resilient load selectively onto or off of the lower arm while the load is compressed between the load clamping arms.
