Imagine what the construction work site would be like today without building construction machine. Without power tools, cranes, mixers, precast concrete panel, we’d be cutting boards and drilling holes by hand. Without heavy equipment, laborers would be excavating sites and digging trenches with shovels and pickaxes. Without the elevator, construction buildings would be only a few stories tall. We can’t expect more than that because human efforts work for that much height only other than that we need advanced Building Construction Machines.
