Electric control system

1.The advanced and reliable electricity equipment: It has the advanced digital technology control. The electric control box has the flexible outside, excellent manufactory crafts. This equipment runs the high-smart control system reliable, steadily and safely in boom control.

2.it’s all equipped with electric elements from aboard with high reliability. Electric control is comfortable for wired remote control and wireless remote control are all in.

Hydraulic system

a. The power system adopts electrical engine and plunger pump with high pressure, low flux pulse and low noise.

b. Balance valves can support safe guard for boom movement.

c. Hydraulic hose and joint are durable, safe and reliable.

Tubular column

The fortified tubular column is adopted. Deformation of the head of the tubular column is 20%~25% less than congener products, it improves the precision for pouring concrete and reduces vibration of the tube.

The connecting structure parts are optimized, and the rigidity of the column is well and the vibration becomes less.
