3. Cost efficiency
DEYING is the leader among manufacturers of tower crane manufacture base in Zhejiang Province.
We inherit Potain technique and modify with state-of-art equipment, which leads to our
up-to-day products. We apply crassitude drum technique, which will solve the common
problem that wire rope twists when in service.
5. Manufacturing Quality
Zhejiang Deying Architectural Machinery Manufacture Co.,Ltd has got the qualification of
tower crane manufacturing with Manufacture License of Special Equipment People's
Tower crane belongs to special equipment of People's Republic of China, the safety of
tower crane is closely relative to people's life and property. DEYING equips safety protector.
Weight limiter uses pull-ring structure made by foreign advanced technique. Moment
limiter is adaptable in hash wildness environment and ensures the limiter is sensitive and
reliable to avoid security accidents caused of malpractice operation of tower crane, like
7. Production Process
①Welding: We apply CO2 gas shielded welding，inverted automatic submerged arc
welding machine welding, semi-automatictrolley-style welding, and arrange instruction,
assessment and confirmation of special process.
②mechanical processing: Standard fixture for mast sections and joint guarantees
the processing precision.
③Paint spray: We apply shot-blast before manual painting to improve the surface intensity
so that the paint could last longer like fresh.
8. Specialization and standardization
The factory is equipped by full facilities, which is divided into four specialized workshop.
The factory takes up 45000m2, , and is now being enlarging. We apply CNC cutting
machine、 Inverted automatic submerged arc welding machine、Gas shielded welder、Milling machine、double-sided milling、shot-blasting、Paint spraying line, etc., all of
which provide outstanding security for high quality of tower crane.
Generally, electric failure covers about 70% of the malfunction of tower crane. To solve
this problem, we choose Schneider electric parts and modify the system, which gives
more assurance to normal performance of tower crane, bringing down malfunction rate.
