Sichuan Construction Machinery (Group) Co., Ltd. is the earliest tower crane design and manufacturing enterprise in China. After more than 60 years of development, in addition to tower crane products, it also involves construction lifts, concrete machinery, large-scale metal structures and military special vehicles.

In 2014, five new tower cranes, C7036, C7015, Q6010, D650, P7527 and P6015, were introduced in SCM, and some economic benefits were achieved.

C7036 tower crane is suitable for all kinds of high-rise buildings, hydropower and bridge projects. The maximum lifting weight is 16t, the lifting weight of the end is 3.6T, the maximum working range is 70m, and the rated lifting torque is 335t.m. The section of standard section is 2 m and 2.5 m, both of which are sheet combined standard section. The walking independent height of standard section is 66.25 m and 53.6 m respectively, and the fixed independent height is 60.65 m and 51.7 m respectively. The standard section of the 2.5m section is independent of height 78.15m and the fixed height is 71.04m.

C7015 tower crane, maximum lifting weight 10t, end lifting weight 1.5t, maximum operating range 70m, standard section 2m, fixed independent height 59.68m. The lifting, slewing and luffing mechanisms adopt variable frequency stepless speed regulation technology.

Q6010 tower crane is a medium and small horizontal arm tower crane. The maximum lifting weight is 6t, the end lifting weight is 1t, the maximum working range is 60m, the standard section is 1.6m, and the maximum lifting height is 153.7m. The variable frequency stepless speed regulation technology is adopted for lifting, slewing and variable amplitude.

D650 boom tower crane is a large boom tower crane with a maximum lifting capacity of 50t, a lifting capacity of 5.9t at the end and a maximum operating range of 60m. The lifting mechanism adopts 217LVF series frequency conversion transmission mechanism, which realizes stepless speed regulation completely; the amplitude conversion mechanism adopts BVF series frequency conversion mechanism, and the braking mode is shoe type and hydraulic double braking. The rotary mechanism adopts RCV series stepless speed regulation system.

P7527 flat-headed tower crane is a large flat-headed tower crane with a maximum lifting weight of 18 t, an end lifting weight of 2.7 t, a maximum operating range of 75 m, a standard section of 2 m and 2.5 m, and a fixed maximum lifting height of 60.7 m and 76.86 m, respectively. It is especially suitable for group tower operation.

P6015 flat head tower crane is a flat head tower crane. The maximum lifting moment is 115t.m, the maximum lifting weight is 8t, the end lifting weight is 1.5t, the maximum working range is 60m, the section of standard section is 1.6m and 2m, the maximum lifting height of fixed type is 45.68m and 54.68m respectively. The lifting, rotating and amplitude changing adopt the most advanced frequency conversion technology at present, the working level is higher, the working efficiency is greatly improved and the performance is stable. Fixed, low failure rate, easy maintenance, especially suitable for group tower operation.

Chuanjian (Group) has always adhered to scientific and technological innovation, focusing on the use of new technologies, new processes to develop new products, and formed a unique rich variety of products. With the brand effect and quality assurance, the construction machinery products marked by "SCM" are widely used in major construction projects at home and abroad.
