前不久，我們收到了一封來自印尼客戶的表揚信。信中提到：“已交付的MHC設備運行穩定可靠，完全滿足各項性能指標要求。”

穩，是客戶最直觀的評價。而除了穩定可靠，這兩臺移動式港口起重機（MHC）在運行經濟性上也下了功夫——把每一次下降產生的能量，變成下一次起升的助力。

01 起重機頻繁作業，能量去哪兒了？

港口作業中，起升與下降是最常見的工況。傳統設備在重物下降時，電機反轉產生的能量通常通過電阻消耗掉，轉化成熱量散發。

這部分能量，其實可以再利用。

GENMA的選配方案：通過多傳動能量回饋系統，把下降過程中產生的電能回饋到電網，供其他機構使用。

簡單說，就是讓設備自己給自己“供電”。尤其在重載下降頻繁的工況，這種方式能有效降低整體能耗，幫助客戶減少長期運營成本。

02 省的同時，穩也沒落下

能量回饋本身不是什么新鮮技術，真正的考驗在于：回饋過程中，設備運行是否依然平穩。

GENMA在控制系統層面做了針對性匹配，確保能量回饋與設備動作無縫銜接——駕駛人員幾乎察覺不到系統在何時介入。既穩穩當當，又節省電費。

不需要額外操作，剩下的交給系統自己完成。

03 成熟技術，用心落地

這套多傳動能量回饋方案已在GENMA移動式港口起重機（MHC）及同類產品中成熟應用。它不是實驗室里的“黑科技”，而是經過項目驗證、能夠為客戶帶來實在收益的可靠配置。從以往已應用項目的實際反饋來看，節能帶來的運營回報遠超預期——投入與產出，形成了正向循環。

印尼客戶的表揚信，是對“穩”的認可；而“節能”，是GENMA用成熟技術為客戶創造的長效價值。

GENMA MHC——穩定可靠，經濟高效。

"We recently received a commendation letter from an Indonesian client, stating: 'The delivered MHCs have been performing reliably and meeting all specified performance requirements.'"

Stability is what our client valued most. But beyond reliability, these two Mobile Harbor Cranes (MHCs) deliver something more—energy efficiency that pays back over time.

01 Where Does the Energy Go in Frequent Lifting Operations?

Hoisting and lowering are the most common motions in port operations. In conventional equipment, when lowering heavy loads, the energy generated by the motor is typically dissipated as heat through resistors.

That energy can be put to better use.

GENMA's solution: A multi-drive energy regeneration system that feeds the power generated during lowering back into the grid for other mechanisms to use.

In simple terms:the crane helps power itself. For operations with frequent heavy-load lowering, this configuration effectively reduces overall energy consumption and long-term operating costs.

02 Saving Energy Without Compromising Smooth Operation

Energy regeneration itself isn't new. The real challenge is maintaining smooth equipment performance during the process.

GENMA's control system is precisely tuned to ensure seamless integration—operators hardly notice when the system is at work. Smooth operation. Lower energy bills. No extra effort required.

03 Proven Technology, Tangible Returns

This multi-drive energy regeneration system is a mature, proven configuration available on GENMA MHCs and similar equipment. It's not a lab experiment—it's a field-validated solution that delivers real results.

Feedback from projects where it's been applied shows thatthe long-term operational savings far outweigh the initial investment. A positive cycle of input and return.

The commendation from our Indonesian client affirms our reliability. The energy savings? That's the lasting value GENMA delivers through proven technology.

GENMA MHC — Stable. Efficient. Sustainable.
