叉车由电池供电的电动机或IC引擎供电。IC引擎的优点是它们可以长时间连续运行，并且不受粗糙地面，灰尘，水和高空气温度的影响。

因此，它们是任何户外操作或通风良好的场所的理想选择。为IC-Engine油箱更换燃料比为电池充电更简单。但是，必须遵守《安全与健康条例》，以控制内燃机的废气。

柴油或液化石油气发动机是首选，因为汽油发动机会排放大量的一氧化碳，因此绝对不能在任何室内运行中使用。

• •柴油机

• 这些发动机是首选，因为它们的功率输出，排放低，寿命长和维护要求低。

• •液化石油气发动机

• 它们由液化丙烷和丁烷的混合物液化石油气提供动力。它们以低排放和低运行噪音而闻名。但是，必须考虑的是，与空气混合的液化石油气会成为易燃易爆的混合物。LP-Gas发动机不允许在没有通风的密闭室内运行，也不得在冷藏室内或冰柜中运行。

Forklift Trucks are powered either by battery powered electrical motors or by IC-Engines. IC-Engines have the advantage that they can be operated continuously for a long period of time and are relatively unaffected by rough floors, dust, water and high air temperatures.

Therefore they are ideal for any outdoor operation - or in well ventilated facilities. Replacing fuel for the IC-Engine tank is simpler than the recharging for the batteries. Safety and Health Regulation must be observed however to control the exhaust gases of the IC-Engines.

Diesel or LP-Gas engines are preferred since Gasoline Engines exhaust high levels of carbonmonoxide and should not be used in any indoor operation at all.

• • Diesel Engines

• These engines are preferred because of their power output, their low emission, their long life and low maintenance requirements.

• • LP-Gas Engines

• They are powered by LP-Gas, a mixture of liquid Propane and Butan. They are recognised for their low emissions and low operating noises. It has to be considered, however, that LP-Gas mixed with air becomes a combustible, explosive mixture. LP-Gas engines are not allowed to operate in closed rooms without ventilation and also not inside refrigerated rooms or in freezers.
