ZSB3000 Spring Balancer

 

 

The ZSB3000 Spring Balancer is a medium-duty ergonomic load-balancing device designed to improve tool handling efficiency, operator comfort, and safety in production, assembly, and maintenance environments. It counterbalances the weight of suspended tools or equipment, allowing them to be operated in a nearly weightless condition. This reduces fatigue, enhances precision, and improves workplace productivity. Constructed with a precision coil spring system, reinforced steel housing, and an integrated safety mechanism, the ZSB3000 provides stable performance, consistent tension control, and long service life. It is ideal for supporting pneumatic tools, torque wrenches, electric screwdrivers, and other suspended devices used in repetitive industrial tasks.

 

 

Key Features

 

 

• Load Capacity up to 30 kg – Supports medium-weight tools with smooth and balanced counterforce.

• Adjustable Spring Tension – Easily fine-tuned to match the exact weight of each tool.

• Durable Steel Housing – Heavy-gauge structure ensures rigidity and long-term protection in harsh environments.

• Smooth Vertical Motion – Provides steady tool movement across the full stroke without rebound or jerk.

• Built-in Safety Lock – Prevents accidental tool drop in the event of spring or cable failure.

• High-Tensile Steel Cable – Braided stainless-steel wire ensures safe and reliable suspension.

• Compact Installation – Suitable for overhead use in production cells or tight work areas.

• Cable Stopper Adjustment – Allows the working stroke to be tailored for operator comfort.

• Low Maintenance – Sealed spring housing minimizes wear and contamination.

• Corrosion-Resistant Finish – Powder-coated surface resists moisture and abrasion.

 

 

Applications

 

 

The ZSB3000 Spring Balancer is suitable for a wide range of industrial and assembly operations, including:

 

 

• Automotive and mechanical assembly lines

• Welding and fabrication stations

• Electronics or appliance manufacturing

Features

 

 

• Cost-efficient, practical, and compact. It uses a rotatory Adjusting Cover for more effortless tension adjustment without burden.
• Fast and convenient installation. Additionally, anti-falling steel wire mounting holes are provided, which must be installed to prevent failure at the original mounting location.
• The housing is made of a rustproof iron shell. The steel wires and nylon ropes are available as an option. Furthermore, a ball-shaped damper can also prevent the tool from reaching a fixed height during its recovery stroke.
