Provided is a jack device easily storable in a storage space of a machine body of a work machine. The jack device includes an arm, a cylinder, a float and a pin. The arm is rotatably connected to the machine body. The cylinder is connected to the arm rotatably about a cylinder rotary axis so as to have an upright posture and a tilt posture. The pin rotatably connects the float to a rod of the cylinder. The jack device is stored in a state where the cylinder is contracted and in the tilt posture and the bottom surface of the float lies along a facing part of the machine body that faces the storage space.

A compact telescoping lift arm assembly includes an outer arm section pivotally connected by a pivot member to a lift carriage vertically slidable on a post and an inner arm section telescopically received within the outer arm section and movable in and out of the outer arm section. The inner arm section has a nesting slot formed at an inner end thereof to nest about the pivot member when the inner arm section is retracted into the outer arm section.

A multipurpose electrical assembly is provided that includes a module receiving an alternating current from a power source in a ceiling and converting the alternating current source to a direct current source. The multipurpose electrical assembly also includes a plurality of devices each having a first connector on a first surface for connecting to the assembly and receiving electrical power from a preceding device and a second connector on a second opposing surface for receiving a following device to be connected to the assembly and for transferring electrical power to the following device. A first device of the plurality of devices attaches to the module, and the plurality of devices can be arranged in any order.

A jack pad device adapted to transfer loads between an aircraft and a jack device for jacking the aircraft, and a method for jacking an aircraft are provided. In one non-limiting example, the jack pad device includes a jack pad body. A jack engagement portion extends from the jack pad body and is configured to engage the jack device. A first coupler is attached to the jack pad body and is configured to couple to the aircraft to hold the jack pad device to the aircraft.

An inline mast adapter configured for attaching a light fixture, where a light fixture is aligned (within 15.24 cm, as measured horizontally, from the center of the light fixture) with an extendable tower mast, when the extendable tower mast is in a vertical position. The inline mast adapter includes a pivot arm, such that a light fixture may be attached from ground level. The inline mast adapter further includes a first gas spring and a second gas spring configured for rotational movement for rotationally moving the pivot arm to a vertical position. Further, the inline mast adapter may be an after-market add on to the extendable tower mast, such that the inline mast adapter is a kit.
