A fuel-tank-equipped working machine is provided, which is capable of securing a fuel tank to be large in a state where the fuel-tank-equipped working machine is secured to be compact. A generator 10 as a working machine includes a fuel tank 25 supported at an outer case 12. The working machine 10 includes a tank opening 35 that is formed at the outer case 12, a mounting concave portion 38 that is formed on the fuel tank 25, and a cushion portion 37 that is capable of being housed in the mounting concave portion 38. The tank opening 35 is formed so as to be able to expose an upper half part 25a of the fuel tank 25 to an outside 14 of the outer case 12. Further, the cushion portion 37 has a fitting groove 63 capable of being fitted to an opening rim 36 of the tank opening 35.

The heat pump includes a terminal block box housing a terminal block for supplying an electric power to at least one electrical device. The terminal block box is supported and made rotatable in a horizontal direction by a hinge. The terminal block box is located between a portion of side plates of a package and electromagnetic valves located on the side of the portion of the side plates. As a result, maintain of electrical devices can easily be performed.

A generator set for a transport refrigeration unit that is operable at a first frequency and a second frequency. The generator set includes a generator and a prime mover. The generator set is controlled by an electronic control unit (ECU) that is coupled to a controller. The ECU is configured to monitor the engine operation condition to obtain an engine operation condition value; whereas the controller is configured to receive the engine operation condition value and compare the value with an engine operation condition threshold. When the engine operation condition value, for example, exceeds the engine operation condition threshold, the controller instructs the ECU to operate the engine at a first speed; and when the engine operation condition value, for example, is below the engine operation condition threshold, the controller instructs the ECU to operate the engine at a second speed that is slower than the first speed.

An electric generator protective cover has a protective cloth cover, a cover assembly, and a plurality of fixing feet. The cover assembly includes a central block located in the center of the top and four elastic supporting rods fixed to the central block. The protective cloth cover is jacked up through the central block and the four elastic supporting rods. One end of each fixing foot is connected to an elastic supporting rod, and the other end is mounted on an upper cross bar of an electric generator frame. The electric generator protective cover has the advantages that the protective cloth cover is arranged, which can isolate dirt such as rain, snow, mud, and sand.

An energy generator includes: an internal combustion engine; a power generator that is driven by the internal combustion engine to generate operating power; a communication interface that receives information given from working equipment; a supply interface that supplies the operating power to the working equipment; and circuitry configured to control at least one of the internal combustion engine and the power generator based on information given from the working equipment through the communication interface.

In the present invention, a package is partitioned into upper and lower sections. An engine and a generator are both disposed in the lower section. In the upper section are disposed: a radiator chamber in which a radiator and a radiator fan are disposed, and an intake chamber in which an intake silencer is disposed. A ventilation hole directly communicates the radiator chamber with an engine chamber in which the engine and the generator are disposed. The ventilation hole is displaced from the radiator fan in a long-side direction of the package. A ventilation hood covers above and around the ventilation hole. An outlet opening of the ventilation hood is formed being displaced in a short-side direction (Y) of the package to face the ventilation hole.

In an embodiment, an integrated ground support system for an aircraft is described herein, the system including a frame on which the system is arranged as a singular assembly. An engine, drive train, alternator, bleed air unit, one or more electrical components, and air cycle machine are mounted on the frame. The engine operates at a first operational state associated with a first rotational speed that is independent of a frequency associated with electrical power, if only the electrical power is to be used by the aircraft, and the engine operates at a second operational state associated with a second rotational speed, different from the first rotational speed, that is a function of a pressure associated with bleed air or the conditioned air, if the electrical power and one of the bleed air or the conditioned air are to be used simultaneously by the aircraft.

Mobile power generation systems and methods for fire suppression therewith include providing a trailer including a rear end, a front end, a bottom end, and a top end, a side panel disposed below the top end and between the rear end and the front end of the trailer and including at least one access door configured to be opened to access an interior space, a gas turbine housed inside the trailer, an electrical generator coupled to the gas turbine to generate electricity and housed inside the trailer, and a fire detection and extinguishing system comprising one or more pressurized bottles stored in the interior space adjacent to and configured to be accessible by the at least one access door.

A mobile power generation system includes a trailer, a gas turbine housed inside the trailer, an electrical generator coupled to the gas turbine to generate electricity, an exhaust silencer system configured to receive exhaust has from the gas turbine, and a noise attenuation assembly coupled to and in fluid communication with the exhaust silencer system. The exhaust silencer system may be attached to a front end of the trailer and may include a diffuser system, a lower exhaust elbow silencer coupled to and in fluid communication with the diffuser system, and an upper exhaust elbow in fluid communication with the lower exhaust elbow silencer and comprising an outlet. The noise attenuation assembly includes an exhaust silencer unit mounted to a top end of the trailer. The exhaust silencer unit includes an inlet in fluid communication with the outlet of the upper exhaust elbow of the exhaust silencer system.

Mobile power generation system and methods using a fixture to position a generator pad assembly in a mobile power generation system include providing a trailer including a rear end, a front end, a bottom end, and a top end, a gas turbine housed inside the trailer having an internal base, and an electrical generator coupled to the gas turbine to generate electricity and housed inside the trailer. The generator pad assembly may include a plurality of generator pads fixed to the internal base, a respective plurality of sole plates positioned above the plurality of generator pads at a spacing, and a supportive material positioned around the plurality of generator pads and the respective plurality of sole plates to fix them in an aligned position. The fixture may be configured to fix the generator pad assembly to the internal base at the aligned position.
