The invention relates to a movable module and to a method of hoisting telescopic towers, preferably wind turbine towers, an ascending section of the tower being hoisted in relation to a supporting section of the tower immediately outside. The movable module preferably comprises at least one hydraulic jack; at least one hoisting cable pre-installed through the hydraulic jack and which remains connected to the jack throughout the performance of the method of hoisting the telescopic tower; and grouping means arranged at the free end of at least one hoisting cable. Advantageously, during hoisting, the movable module is temporarily fixed to the head of the supporting section, and the grouping means (4) are temporarily fixed to the base of the ascending section.

An engine device for generating continuous lift operation is disclosed. The engine generates a continuous lift operation using one or more solenoids. Each solenoid coil has a plunger. Both solenoid coils are open ended, thereby allowing the plungers to move from the front to the back of its solenoid coil. The engine further comprises one or more brackets including a carriage bracket and a mounting bracket. Both the solenoids and the plungers are mounted on the carrying bracket. The mounting bracket is attached to a load that would be propelled. Once it is attached, the pilot or operator will energize the initiatory solenoid coil and de-energize the drive solenoid plunger by striking the extended portion. When the drive solenoid strikes the bumper at the top of the mounting bracket it de-energizes and returns to the original position by return springs. This firing action is repeated for providing continuous propulsion.
