Multi-function truck

A multi-function truck, comprising:

• a load-carrying platform for carrying a load;
• a pump having a motor, mounted in a space below said load carrying platform and driven by electric power from an AC power supply at a collection site;
• a liquid collector loaded on said load-carrying platform, wherein said liquid collector can be unloaded from said load-carrying platform;
• a first connecting hose having the length enough to connect a pipe-end of a suction or a delivery of said pump to said liquid collector loaded on said load-carrying platform;
• a second connecting hose having the length enough to connect another pipe-end of said pump to receive collected liquid from an on-site liquid container placed at the collection site;
• a plug for connecting said AC power supply to said motor;
• and
• a switch disposed between said plug and said motor, wherein said switch automatically intercepts electric current from said AC power supply, when a load of electric current exceeds a predetermined value,
• wherein said motor mounted in the pump is driven by electric power selectively received from a generator mounted in a space below said load-carrying platform or said AC power supply.
