The most notable feature of the CP7748 is its torque output and industrial-grade durability.It employs a heavy-duty vane motor and a specially heat-treated alloy steel impact mechanism capable of withstanding continuous high-load impacts.The housing is made of die-cast magnesium,making it lightweight while offering high structural strength to effectively protect internal precision components.The front of the tool features a large heavy-duty protective sleeve to prevent impact damage.The handle integrates a high-flow regulator and a forward/reverse switch for direct and powerful operation.For easier operation in confined spaces,some models offer a side exhaust option.

The specifications of the CP7748 are impressive.Its maximum reverse torque reaches 2200 ft-lb(approx.2983 Nm),with a free speed of about 5500 RPM.The air inlet is a larger 3/8"NPT to meet its high air consumption needs,with an average consumption of about 12 CFM.The total weight is about 7.5 kg,with a length of about 315 mm,classifying it as a large pneumatic tool.The working air pressure range is 90-100 PSI.Such powerful specifications allow it to easily handle large bolts from M24 to M36 size.The design of its impact mechanism also optimizes torque transfer efficiency,ensuring every bit of air pressure is converted into effective tightening force.
This wrench is primarily used in ultra-heavy industries.In mining and construction sites,it maintains track links,drive sprockets,and bucket linkage bolts on excavators,loaders,and cranes.In heavy truck repair centers,it handles giant nuts on axles,differentials,and wheel hubs.In power plants and metallurgical factories,it is used for dismantling flange bolts on large fans,pumps,or rolling mill equipment.It is also commonly used in ship repair and bridge construction,serving as the solution for extreme fastening tasks.
