Described remote control equipment (RCE) comprises: control handle, in order to produce and emissioning controling signal; And receiver of remote-control sytem; In order to receive the signal of described remote control handle, control the work of tower crane after treatment, wherein, described executive device comprises:

The output of encoding of CPU microprocessor, the energizing signal that produces when will press button switch;

Governor circuit is electrically connected to the CPU microprocessor, in order to CPU microprocessor encoded signals is exported; It is the state of kinematic motion of tower crane.

Direct supply is electrically connected on the CPU microprocessor, and with thinking that described CPU microprocessor provides working power, it is the 12V direct supply.

Described pull up circuit comprises:

Source of AC for the 220V source of AC, is electrically connected to governor circuit, for tower crane provides operation power.

Sensor is electrically connected to the CPU microprocessor with after governor circuit is connected, and feeds back on the CPU microprocessor in order to the service condition with governor circuit.

Described display circuit is electrically connected on the CPU microprocessor, in order to detect and to show the service condition of governor circuit.

As a kind of preferred version of the present utility model, described remote control equipment (RCE) comprises: 4 control handles, satisfy operating personal control to tower crane in four orientation in roof enquiry place, four control handles can use one separately, also can use two or four simultaneously all uses, but four remote controller self interlockings, other can not job of work.

As another kind of preferred version of the present utility model, in the described CPU microprocessor, contain 4 control circuits, receive, control the electric signal of 4 remote control handles respectively.

Described CPU microprocessor is electrically connected with display circuit, sensor, governor circuit, receiver of remote-control sytem, 12V direct supply respectively, and described governor circuit is electrically connected with 220V source of AC and 12V direct supply in turn.

Because the utility model adopts said structure, has the following advantages:

1, remote control distance satisfies the needs of high-low storey building greater than 500 meters.

2, remote controller has the overweight protection of tower crane, each road work indication, and the four sides above tower crane has each way sign indicating number to show; show No. one remote controller of working, below the sport car of arm, the overweight protection of electronics is housed; when the weight of object of lifting exceeds allowed band, can not rise, can descend.

3, on the basis of former tower crane circuit, control desk is changed in repacking, and former machine performance is not had influence, and can realize moving operation of former tractor driver and remote control compatibility function.

Therefore, the utility model is easy to use, safe and reliable, accuracy is high, has very high social value and market popularization value.
