Sany Heavy Industry Co Ltd , China's largest construction machinery maker, could raise up to $3.33 billion in the second biggest stock offering this year in Hong Kong, braving volatile markets to raise funds for expansion of its factories.

The company, which makes concrete pumps and truck cranes, is offering 1.34 billion shares for HK$16.13-HK$19.38 each, putting the total deal value at up to HK$25.97 billion ($3.33 billion), according to a term sheet seen by Reuters on Monday.

The sale would be the biggest since commodities trader Glencore raised nearly $10 billion in a dual listing in Hong Kong and London and would top a $2.5 billion initial public offering by luxury goods maker Prada SpA in June.

Sany Heavy's offering comes on the heels of a slew of deals that hit Hong Kong's equity capital market last week after it ground to a halt for nearly two straight months with no share sales as investors shunned turbulent global markets.

Citic Securities Co Ltd , China's largest publicly traded brokerage, began meeting investors on Friday to market an up to $1.94 billion Hong Kong deal.

Chinese consumer companies, including Tea maker Tenfu Holdings Co Ltd and shoe retailer Hongguo International Holdings Ltd , recently launched $485 million worth of IPOs in Hong Kong.

Bank of America Merrill Lynch , Citic Securities and Citigroup Inc were tapped as joint global coordinators to manage the Sany offering.
