Description

Technical Field

[0002] With the growing global fuel shortage and increasing public awareness of environmental protection, new energy engineering equipment has become a hot topic for those in the construction machinery industry. New energy vehicles are already widely used in passenger vehicles, with significant breakthroughs and advancements in new materials, microprocessor performance, and large-capacity batteries. With the advancement of technology and the need for environmental protection, the innovative research, development, and application of mobile new energy engineering machinery has become extremely necessary.

[0003] Currently, the power sources used by construction machinery equipment primarily come in three forms: 1) powered entirely by fuel-powered engines; 2) powered entirely by pure batteries; and 3) some wheeled cranes utilize hybrid systems that combine engines and batteries. New energy cranes are a growing trend, and given the need for cranes to maintain a certain range while also being able to lift heavy objects, hybrid cranes are expected to capture a significant share of the market in the future.

[0004] However, existing remote speed control devices for fuel-only or battery-only cranes can only control the speed of a single power source, failing to meet the needs of hybrid cranes for simultaneous control of both power sources.
