Disclosed herein is a tire handler for the movement and manipulation of tires and wheels for large vehicles. The tire handler is lifted by a crane or similar hoisting equipment. The tire handler comprises improvements including an automatic leveling system, power adjustable tire control and support arms, and wireless remote operation of powered functions.

A suspension type lifting device includes a base unit, a bearing unit, a balance unit, a servo unit and a hanging unit. The base unit includes a first plate, a second plate and a third plate. The bearing unit includes a positioning piece and two forks. The balance unit is connected with the third plate of the base unit. The servo unit is connected with the first plate of the base unit. The hanging unit is mounted on the first plate of the base unit. When the servo unit detects that a foreign object is placed on the bearing unit, the servo unit calculates a value required for reaching a balance weight and transmits a power to drive the balance unit to swing leftward and rightward, so as to reach a balance state.

A crusher hammer lifting device facilitates raising and lowering of a hammer mountable at a rotor of a horizontal shaft impact crusher (HSi-crusher). The device includes a main body, a mount engager for attachment to an auxiliary lifting tool and a hammer attachment for releasably mounting the hammer in a rotatable manner at the device.

The present disclosure is directed to the transport of one or more loads of items including building materials and/or other items to one or more target surfaces including one or more elevated surfaces. The present disclosure is also directed to the holding of one or more loads of items including building materials and/or other items during transport to one or more target surfaces including one or more elevated surfaces. The present disclosure is also directed to the holding of one or more loads of items including building materials and/or other items on one or more target surfaces including one or more elevated surfaces.

The present disclosure relates to a crane arrangement (2) comprising a crane controller (200) for control of movement of a crane tool assembly (10) arranged at a second, free end of a crane boom system, said crane controller being arranged to receive a directional command for rotational displacement of the tool around its rotation axis, z_r, from an initial pointing direction, x0, of the direction indicator (11) of a tool (9) and to based thereon control at least one of said plurality of actuators to perform displacement of the tool around its rotation axis, z_r according to the directional command to a desired pointing direction, x1, of the direction indicator. The crane controller is further arranged to receive a drive command for movement of the crane tool assembly and to control at least one of said plurality of actuators to perform movement of the crane tool assembly along the desired pointing direction, x1, of the direction indicator (11) of the tool (9).
