1>. FSH, FSM-Series, Hydraulic and Mechanical Wedge Spreaders
Enerpac industrial mechanical and hydraulic spreaders feature an integrated wedge concept: Friction-free, smooth and parallel wedge movement eliminates flange damage and spreading arm failure
For maintenance, commissioning, shutdowns, testing and valve change outs
Unique interlocking wedge design - no first step bending and risk of slipping out of joint
Requires very small access gap of only 6 mm
Stepped spreader arm design - each step can spread under full load
Few moving parts mean durability and low maintenance
