Abstract: Device (1) for lifting objects, such as electric motors for industrial fans, comprising: a base provided with wheels (15, 16); a base frame (3) arranged on the base; a lifting frame (5) movable in vertical direction relative to the base frame (3), wherein the lifting frame (5) comprises a holder (6) configured to hold the object; a double-action hydraulic cylinder (82) configured to displace the lifting frame (5) relative to the base frame (3).

Abstract: Device for removing a bundle from the casing of a heat exchanger, comprising a carrier frame provided with pulling means for removing the bundle from the casing, wherein the carrier frame is adapted to hold the bundle removed from the casing, wherein the device is provided with hoisting means for hoisting the carrier frame, wherein the hoisting means comprise at least one gripper and wherein the device is also provided with connecting means for connecting the gripper releasably to the carrier frame.

Abstract: The invention relates to a device for engaging objects, such as heat exchangers of varying sizes. The device includes at least one gripper provided with at least a first and a second gripper arm, at least one of which is movable with respect to the other gripper arm for enclosing an object therebetween; and a driving mechanism connected to at least one of the first and second gripper arms for closing or opening the gripper as needed, wherein at least one of the first and second gripper arms includes a first and a second gripper arm part that are pivotally coupled together, and an adjusting mechanism provided between the first and second gripper arm parts, the adjusting mechanism being arranged for adjusting the angle between the gripper arm parts in dependence on the diameter of the object to be engaged prior to engaging the object.
