HTM-H Series Heavy Planetary Torque Multipliers
Engineering Overview & Structural Features
The HTM-H Series Heavy Planetary Torque Multipliers deliver high-efficiency mechanical torque multiplication for heavy industrial bolting applications where electrical or hydraulic power is unavailable. Delivering high-torque outputs of 3,000 N·m and 4,500 N·m (2,200 to 3,300 lbf·ft) with 15.5:1 and 26:1 planetary gear reductions, these tools allow a single operator using a compact manual torque wrench to tighten or loosen high-strength fasteners with precision repeatability better than ±4%.
HIGH GEAR REDUCTION RATIOS
High torque multiplication ratios of 15.5:1 (HTM-H-3000) and 26:1 (HTM-H-4500) enable operation with a small, lightweight manual torque wrench, eliminating hazardous cheater pipes while maintaining torque repeatability within ±4%.
ANTI-BACKLASH SAFETY DEVICE
Integrated mechanical anti-backlash ratchet mechanism retains wind-up gear force at each stroke increment, eliminating dangerous spring-back recoil for safer and smoother manual operation.
PRECISION TORQUE-ANGLE INDICATOR
Calibrated rotational angle dial provides clear, direct monitoring of tightening torque and angle, facilitating seamless adherence to structural turn-of-nut fastening protocols.
450 MM HEAVY TUBULAR REACTION ARM
Heavy-duty tubular reaction arm safely transfers reaction torque against neighboring structural members. Solid planetary gear construction ensures minimal maintenance and prolonged service life.
* Note: Dimensional codes: A = Body Outer Diameter (108 mm), B = Multiplier Height (156 / 173 mm), C = Tubular Reaction Arm Length (450 mm).
OEM Cross-Reference & Dimensional Interchangeability
Heavy manual planetary torque multipliers delivering 3,000 to 4,500 N·m with 15.5:1 and 26:1 reduction ratios, anti-backlash safety, and ±4% precision. 3000 - 4500 Nm Multipliers.
