Electric single-girder crane is a kind of light lifting equipment. Electric hoist is suspended under the I-beam track under the single-girder. It can be divided into electric hoist and manual hoist. Heavy objects are suspended on it, which is relatively simple and widely used. It is mainly composed of electric hoist, metal structure (one main beam and two end beams), cart running mechanism, feeding device and electrical device. Shanghai Biba Electrical and Mechanical Equipment Co., Ltd. is a crane refitted wireless remote control, crane remote control sales




The conventional operation modes of single girder crane can be divided into two types: driving (also known as aerial exercise) and ground operation.


Driving exercise is the abbreviation of cab operation, that is, the operator goes up the escalator to the crane cab for operation. The advantage of driving is that it is almost free from the restriction of the ground environment, and the operator has a better view. You can sit in the cab and work relatively easily. The drawbacks are: special operators are needed; ground personnel are needed to cooperate; ground personnel are required to direct when large pieces are dropped or when accurate lifting is needed; accidents are easy to occur; and the cost of the cab is relatively high.


Ground drilling is the operation of the ground operator through the stripline control button box drawn from the control box. The advantage is that the operator does not need to climb to the crane, simple operation can be completed by one operator, which can save personnel, save intermediate command and improve work efficiency. The disadvantage is: because of the belt operation, the operator needs to walk synchronously with the crane, the labor intensity is high, the walking route is limited by the ground conditions, and can not avoid the obstacles on the ground. When lifting large pieces, the operator needs to operate close to the lifting parts, which has greater danger. At the same time, it is impossible to avoid toxic, harmful and polluting occasions. Wire-pulling button box often shakes and pulls, which is easy to break the wire, and cause faults or even accidents.


In view of the shortcomings of the above operation mode, Shanghai Biba Electrical and Mechanical Equipment Co., Ltd. specially introduced the wireless modification service of cranes. To change crane operation to wireless remote control operation is to install a wireless transceiver system (industrial wireless remote control) without changing the original crane electrical control principle and safety protection. The wireless transceiver system is divided into two parts: transmitter and receiver. The operator transmits the operator's operation instructions digitally coded and encrypted by transmitter to the remote receiver by wireless way. After decoding and conversion, the receiving system restores the control instructions to the output of relay signals to realize the wireless control of the crane. After the crane is equipped with a remote controller, the operation, mooring and hooking can be undertaken by one person alone without command, thus saving the cost. Human resources; because operators operate on the ground and independently judge the running state of the vehicle, the accuracy and consistency of the operation are significantly improved than before; operators can choose the best angle to avoid the poor visibility, serious pollution and dangerous operation location, improve the working environment of operators; improve the safety of operators and other staff. The remote control transformation of crane is to install a set of remote control equipment without changing the original operation mode. These two sets of operating equipment can be used as standby (through switch selection), which to some extent improves the reliability of driving.
