ZTHB65 Spring Balancer
The ZTHB65 Spring Balancer is a heavy-duty tool support system engineered to suspend and counterbalance large, high-torque industrial tools. It is designed to reduce operator fatigue, improve tool handling safety, and enhance workflow efficiency in demanding assembly or maintenance operations. Featuring a reinforced cast-aluminum housing, a high-strength coil spring, and an integrated safety locking system, the ZTHB65 provides reliable load balancing for weights of up to 65 kg. Its robust construction and precise spring tension mechanism make it ideal for continuous use in automotive, shipbuilding, aerospace, and heavy-equipment manufacturing environments.
Key Features
High Load Capacity up to 65 kg – Supports heavy pneumatic, hydraulic, or electric tools with stable counterbalance.
Precision Tension Adjustment – Allows fine-tuning of spring force to match exact tool weight for smooth, balanced operation.
Rugged Cast-Aluminum Housing – Ensures durability, impact resistance, and long service life under industrial conditions.
Smooth Vertical Movement – Enables effortless lifting and positioning without sudden retraction or rebound.
Integrated Safety Lock System – Prevents accidental tool fall if spring or cable tension is lost.
High-Tensile Wire Cable – Braided stainless-steel cable provides strength and resistance to wear.
Dual Support Hook Design – Offers secure mounting and stable load suspension for heavy tools.
Sealed Spring Chamber – Prevents dust and contaminants from entering the housing, extending spring life.
Maintenance-Free Operation – Pre-lubricated components ensure smooth, reliable performance.
Corrosion-Resistant Coating – Protects against rust, oxidation, and surface damage in harsh environments.
Applications
The ZTHB65 Spring Balancer is ideal for heavy-duty industrial operations that involve the use of large or high-torque tools, including:
Automotive and truck assembly lines – supporting large impact wrenches and torque multipliers.
Shipbuilding and heavy machinery plants – counterbalancing drills, grinders, and riveting hammers.
Aerospace and defense industries – handling precision fastening tools or heavy torque equipment.
Construction and fabrication workshops – supporting welders, cutting torches, or lifting fixtures.
Maintenance and repair operations – reducing operator strain during repetitive or overhead work.
Performance Advantages
Ergonomic Operation – Eliminates tool weight resistance, allowing easy and safe handling of heavy tools.
Superior Safety – Built-in locking and overload protection system prevents tool drops.
Consistent Performance – Maintains steady balancing tension throughout full cable travel.
Long Service Life – Heavy-duty components and enclosed design resist wear and contamination.
Improved Productivity – Reduces operator fatigue, enabling longer and more efficient work sessions.
Low Maintenance – Enclosed and pre-lubricated spring requires minimal servicing.
