The invention provides a forklift imbalance alarming device and method. The forklift imbalance alarming device comprises a weighing sensor, a main processor and an alarming device body. The forklift imbalance alarming device is characterized in that the weighing sensor is used for measuring pressure generated by a left fork and a right fork when a forklift is loaded and transmitting the measurement result to the main processor; the main processor judges whether the forklift overloads or is imbalanced and outputs the condition to the alarming device body to remind operators when the forklift overloads or is imbalanced; the alarming device body is used for receiving and displaying the signal about the forklift overload or imbalance condition transmitted by the main processor. The forklift imbalance alarming device and method can calculate various overload and imbalance conditions possibly occurring to the forklift, feed the conditions back to the operators by many means in time, and ensure operation safety of the forklift.

The invention discloses a rollover resistant control method of a forklift. The rollover resistant control method comprises the steps that the forklift is subjected to altitude grading by calculating the transverse load transfer ratio of the forklift and according to the safety degree, when the forklift is in a stable state, free control is conducted; when the forklift is in a first level rolloverstate, first level rollover resistant control is conducted; and when the forklift is in a second level rollover state, second level rollover resistant control is conducted so as to improve the rollover resistant capacity of the forklift. The rollover resistant control method of the forklift can conduct stable control over the forklift, so that the forklift is prevented from rollovering in the carrying and working process, and accordingly the transverse stability and the active safety of the forklift are improved.

The invention discloses a multifunctional medical elevator car which comprises a car body, a ventilation device and a lighting device The multifunctional medical elevator car is characterized in that the ventilation device is arranged at the top of the car body, the front side wall of the inside of the car body is provided with an oxygen storage cabinet and a medical article cabinet, the fronts of the two cabinets are respectively connected with a cabinet door in a hinged mode, an oxygen storage bottle and a supplying device connected with the oxygen storage bottle are arranged in the oxygen storage cabinet, chairs are arranged on the left wall and the right wall of the inside of the car body, and the inner bottom face of the car body is symmetrically provided with two anti-slip rubber strips The elevator car is reasonable in structure, complete in function and capable of meeting various use requirements in a hospital

Multifunctional medical elevator car

The invention provides a warning device for falling of a double-column car elevator. The warning device comprises a double-column car elevator body. The double-column car elevator adopts multiple trays to elevate a car, wherein the trays are lifted in the vertical direction of two supporting columns. The warning device comprises a single-chip microcomputer, an alarming device and pressure sensorsarranged on the trays. The pressure sensors are connected with the single-chip microcomputer through a variable resistance circuit. A variable resistance box with the adjustable resistance value is arranged in the variable resistance circuit. When the trays elevate the car, the weight of the car presses the pressure sensors to enable the resistance value to change so as to change output level of the variable resistance circuit to the single-chip microcomputer, and when the output level changes and reaches a threshold value, the single-chip microcomputer judges that the risk of falling of the car of current lifting motion is large, and controls the alarming device to give an alarm. According to the warning device, the stress situation of all the trays of the elevator can be detected, and thus falling-preventing detection can be carried out on elevating operation of the car effectively.

The invention discloses an elevator car device designed for infants in a humanization manner. The device comprises a car wall, a car roof, a car bottom and a car door. A lamp special for the infants is arranged on the car roof. The car wall is provided with a foldable infant shelf, and hooks are arranged on the lower side of the shelf. The car wall is further provided with a display screen. A safety warning belt is arranged at the position, close to the door, of the car bottom. A garbage can is further arranged at the car bottom. According to the elevator car device designed for the infants in the humanization manner, inconvenience generated when the infants go out to take an elevator is fully considered; the asleep infants can be temporarily put on the shelf; the attention of crying of the infants caused by too many people can be temporarily distracted through the infant music lamp and the display screen; convenience is brought to outgoing infant orderlies; and the safety of the infants is ensured through the safety warning belt.

The utility model relates to an anti-overload and anti-rollover forklift with an alarm function The anti-overload and anti-rollover forklift comprises a pressure sensor, a connector, an arithmetic device, a controller and an audible and visual alarm, wherein the pressure sensor, the connector, the arithmetic device, the controller and the audible and visual alarm are connected sequentially; the pressure sensor is used for converting a pressure signal into an electric signal, the electric signal is transferred to the audible and visual alarm by the connector, the arithmetic device and the controller and is converted into an acousto-optic signal, the acousto-optic signal is subjected to overloading and unbalance loading voice prompts and a lamplight prompt; and the audible and visual alarm has a left unbalance loading voice prompt, a right unbalance loading voice prompt, an overloading voice prompt, and a lighting prompt The anti-overload and anti-rollover forklift has the advantage of simple structure, safety, reliability and capability of measuring whether the overloading or unbalance loading of forklift occurs or not accurately, failure and even rollover which are caused by the overloading or the unbalance loading can be avoided effectively, the service life of the forklift is prolonged effectively, safety production is realized, and the production efficiency is improved

Anti-overload and anti-rollover forklift with alarm function

The utility model relates to an elevator cab with seats and hooks. The elevator cab with the seats and the hooks comprises an elevator cab, foldable seats are installed on side walls of the elevator cab, and hooks are installed at the corners of the elevator. The elevator cab with the seats and the hooks has the advantages that the structure enables the old, the weak, the sick, the disabled, the pregnant and the children especially the specific people carrying heavy items to reduce fear and discomfort to the uttermost due to the fact that the old, the weak, the sick, the disabled, the pregnant and the children especially the specific people carrying heavy items often come in and go out high-rise buildings such as hospitals, hotels, shopping malls and residence, so that the people can arrive at a destination smoothly.
