![Akkerman]()
Operators using a GBM 48 Series jacking frame have precision, two-speed advancement control options through the gear box for installing GBM tooling. The 100-ton fast and 265-ton slow advance speeds with 100-tons of pull-back force give operators complete control over GBM accessories. The rotational torque operates in two ranges of force, 0-10,500-ft-lbs. and 0-26,000-ft-lbs. to match the tooling requirements. Each torque range offers two speed options with 35 and 50-rpms in the low torque and 23 and 35-rpms in the high torque settings. The GBM 48 series frames are able to install up to 48" (1,219 mm) OD pipe in 8' (2.4 m) lengths. Frames extensions for 10 and 20' (3,6 m) pipe lengths are available. The frame's 7.5" (191 mm) cylinders either have a 30" (762 mm) or 40" (1,016 mm) stroke, and latch on center every 12" (305 mm).
