JET® JHJ series bottle jacks are used for multiple applications: pushing, bending, pressing, or straightening. With base and cylinder electrically welded together to assure strength and eliminate leaks, extreme temperatures do not affect them. The low profile truck models or standard models vary in capacities from 12-1/2 tons to 100 tons. All JHJ series bottle jacks comply with ANSI/ASME B30.1 and PALD-1 standards.
