| Bevel Gear Lifting Jacks. These jacks do not use worm gearing but bevel gearing. All quick-lifting screw jacks are equipped with hardened, sharpened and spiral-toothed bevel gearbox ensures higher efficiency, higher lifting speed, greater duty cycle and a longer service life. The "JTQ" Jacks are modular design in 4 sizes. Each size is available with gear ratios 1:1 and 2:1. Gear housings are cubic design housing, compact and robust, they are made of aluminum alloy with anodizing. Compared with cast iron gearbox, it is lighter in weight, higher in strength, and easier to dissipate heat. | |||||||||

Product Description
Bevel Gear Jacks for High Speed 10kN Load Capacity, Self-locking ACME screw Tr30x6, Gear ratio 1:1 and 2:1. These screw jacks do not use worm gearing but bevel gearing. All bevel gear screw jacks are equipped with hardened, sharpened and spiral-toothed bevel gearbox ensures higher efficiency, higher lifting speed, greater duty cycle and a longer service life. Gear housings are cubic design housing, compact and robust, they are made of aluminum alloy with anodizing. Compared with cast iron gearbox, it is lighter in weight, higher in strength, and easier to dissipate heat. All bevel gear jacks work in all installation positions. Due to their cubic casing they can be mounted flexibly.
Compared with worm gear machine screw jacks, the "JTQ" screw jacks are more efficient and used in applications requiring higher dynamics and higher duty cycle up to 40%. They can be driven directly by electrical motor or other engines, or manually operated. The highest input speed is 750rpm. Especially suitable for high-frequency and high-speed working conditions, the maximum lifting speed is up to 75mm/s (4500mm/min) with single lead screws, and 150mm/s (9000mm/min) with double lead screws. There are no "standard"travel lengths (stroke), all orders manufactured according to the user's requirements.
All "JTQ" screw jacks are are functional in every installation position and can be mounted flexibly thanks to the cubic form. According to the customer's request, they are delivered with one shaft, two shafts, three shafts, and four shafts configurations. Custom-built to meet your specifications, they can be seamlessly configured into arrangements comprising multiple jacks. As an added benefit, "JTQ" bevel gear jacks also act as 90 degree boxes, do not therefore require additional bevel gearboxes, making them an ideal choice for the multi-jack systems. Simple and effective solution in comparison with hydraulic and pneumatic systems.
