Product advantages:

Portal cranes are widely used in ports, docks, storage yards and other places to complete the loading, unloading and reloading operations of ships and vehicles. Its design, manufacture, and inspection implement advanced domestic and foreign standards such as DIN, FEM, IEC, AWS, and GB, as well as the latest national standards.

According to the jib structure, the portal crane is divided into two types: single jib and four-link. The single-arm portal crane has simple structure, large lifting capacity and light weight. The four-link portal crane adopts a combined boom system to realize the horizontal movement of goods during the luffing process, and has the characteristics of small horizontal drop, stable luffing and low power consumption. Both types of portal cranes can meet the loading and unloading requirements of breakbulk cargo, bulk cargo and containers, and have the characteristics of wide application range, high operating efficiency and stable operation of the whole machine.

At present, the main product specifications are MQ1025, MQ1030, MQ1625, MQ1630, MQ1635, MQ2525, MQ2530, MQ2535, MQ4025, MQ4030, MQ4035 single-arm and four-link portal cranes.

Features:

1. Automatic follow-up function for full rotation of the spreader

2. Adopt active inverter technology; it can convert the kinetic energy and potential energy stored in the machine into electrical energy, which can be efficiently fed back to the power grid

3. Inhibit the pollution of high-order harmonics to the power grid and improve the power factor of the whole machine

4. Record all the parameters of the action in one or more working cycles, and realize the automatic cycle execution of this action by the grab through reasonable optimization of the calculation of the wiring harness and the acceleration and deceleration time

5. Calculate the running acceleration of the lifting point according to different actions, set up segmented protection, find out the stalling trend in advance, combine with the hardware overspeed switch, realize double protection, and prevent the occurrence of stalling accidents limitedly

6. When the spreader is lifted to a limited height, the control relay will make the buzzer on the control box alarm, and at the same time the lifting action will stop, and only the lowering operation can be performed, so as to prevent the lifting hook from being over-rolled
