Surface coating technique
The surface of the entire steel structure is pretreated with shot blast technique by 2 times to remove the traces of rust, meanwhile increase the adhesion and durability of paint.
Be available for different speed control modes, such as frequency conversion control, tandem resistor speed control, pole-changing control and voltage-variation control and etc. in the aim to meet the needs of the different users.
The hoisting, slewing, trolley mechanisms all feature wide-range speed variation, steady start up and braking, low impact, capable of persistent low-speed operation, precise positioning and easy maintenance.
Major electric components are sourced from world leading brands with greater stability and reliability.
It is convenient to maintain the tower cranes for the simplicity of electric circuits design and orderly layout inside the electrical cabinet.
Panel design mast section possesses excellent strength, easy installation, economical maintenance along with convenient transporting. It can save at least 60% of the transportation cost compared with monobloc mast structure.
With great comfort, air-conditioning and humanized design, cabins of our tower cranes provide the operator with optimum view and most enjoyable working environmen
