Client’s working site is in the Jungle, in the areas it usually takes several hours to reach the destination. The reason why the client want to have a electric type concrete pump is because that in his work site, a lot of workers are less educated and lack of operation instructions, so since their primary target is diesel type pump, but in the end they go for electrical one, because compare to the diesel type, the electrical type pump will have an emergency stop when the machine is overload, so they decided to go for it without hesitate.
