BGA Series High-Efficiency Hand-Wheel Screw Jacks: Safe Manual Lifting Solutions

1. Product Overview

The BGA Series Hand-Wheel Screw Jack is a specialized lifting device designed for manual operations. Optimized for minimum handle effort, this series combines the durability of trapezoidal screws with the agility of bevel gear sets, delivering high operational efficiency and absolute precision.

2. Key Technical Features

  • Excellent Self-Locking: Thanks to the bevel gear mechanism paired with trapezoidal screws, the unit features a self-locking function at any position within the stroke without requiring auxiliary brakes, ensuring maximum user safety.

  • Effortless Operation: The drive system is precisely engineered to allow users to lift heavy loads with minimal input torque and fewer hand-wheel revolutions.

  • High Durability & Long Lifespan: The reduction gear mechanism uses standard grease lubrication, ensuring smooth operation, reduced wear, and lower maintenance costs.

  • Versatile Load Range: Available in capacities from 10 kN to 300 kN, suitable for applications ranging from civil engineering to heavy industrial projects.
