FDZX-HL-10T Combined Hoisting Weight Limiter
Example: It is known that the rated lifting capacity of the electric hoist is 10T, the pulley magnification is 4/1, the wire rope diameter is 15, and the side pressure sensor is required, and the length of the hand display cable is 12m, then the model code is FDZX-HL-10-4/1-Փ15.
(1) The whole machine consists of two dedicated digital integrated circuits: a single-chip digital amplifier/analog-to-digital converter, and a single-chip microprocessor circuit.
(2) The dedicated digital integrated circuit system has high precision, good stability and strong anti-electromagnetic interference ability.
(3). With keyboard lock, with delay setting judgment and dynamic stability recovery function. The two-step calibration method (zero adjustment, loading amount) is adopted, which is accurate, fast, simple, and has strong product versatility.
(4). Its shell adopts sealed aluminum waterproof box, which has high mechanical strength and high protection level.
(5) It forms an integral lifting weight limiter with the side pressure sensor.
(6) It can be combined with shaft pin sensor, plate pull sensor and other types of sensors to form various types of lifting weight limiters for various lifting occasions.
