Chaochai 485 bore engine settled in Tang Jun Eo Ling and Shandong Kama


Recently, the technology center two 485 engine project engineer came to Shandong, matching the Kama and Tang Jun Europe bell prototype vehicle to do technical guidance toward the loading of six small-bore diesel engines.

This time, Chaochai provided two CY4A55-E3A engines to the Kumah 5047AS3XXY (2800 wheelbase) vehicle for Shandong Kaima Automobile Manufacturing Co., Ltd.; and four CY4A55s for Shandong Tang Jun Ouling Automobile Manufacturing Co., Ltd. The E3A engine is matched to the ZB1020BDBS (2700 wheelbase) and ZB1040LDCS (2800 wheelbase).

With the strong cooperation and support of the Shandong office, the prototype has been successfully fitted to the vehicle at the Kama Motors. The auto plant has responded well.

The successful assembly of this prototype has laid a good foundation for the small-bore engine capacity in 2010.

Tower Crane Power Cable

BQ supplys two types of Tower Crane Power Cable, YC Electric Power Cable and YCW Insulated Power Cable.


Power Cable is used for heavy industry including mining and marine, they must be robust and capable of handling both torsional and tensile stresses simultaneously. These mobile machines for lifting and handling are often manufactured with a robust rubber outer sheathing to protect against the constant reeling and movement as well as providing protection against oils and greases. Cables with Polyethylene (PUR) and PVC sheathing are also available. The cables are UV resistant – applications such as tower cranes and port loading gantries are subject to the elements – as well as being resistant to oils and greases.


The power cable used for a tower crane is typically a heavy-duty and high-voltage cable to handle the electrical power requirements of the crane. These cables are designed to be durable, flexible, and capable of withstanding harsh weather conditions. They are usually made of materials such as rubber or neoprene for insulation and protection against abrasion, oil, and chemicals. The exact specifications of the power cable may vary depending on the specific model and power requirements of the tower crane.
