Hydraulic Bolt Tensioning Service
Calibrated hydraulic bolt tensioning for slewing bearing installation with correct pre-load, staged sequence and full record.
Professional Hydraulic Bolt Tensioning Service by Active Ship Management at Chittagong Port, Matarbari Port, Mongla Port, Payra Port — Bangladesh.
Active Ship Management provides calibrated hydraulic bolt tensioning service for slewing bearing installation on ship deck cranes. Slewing bearing bolts must be pre-loaded to maker-specified value in the correct crossing sequence — hand-torque and torque wrenches cannot reliably achieve the required pre-load on large-diameter high-strength bolts.
We use calibrated hydraulic tensioning tools sized for the bolt, apply pre-load in staged crossing sequence per maker instruction, verify final pre-load and issue a full tensioning record acceptable to class.
Scope
- Tensioning tool selection
