Material: The spring balancer uses thickened steel wire rope, thickened to prevent rotation, strong load-bearing capacity, good toughness and tensile resistance. Note: Check the spring balancer regularly for signs of wear or damage. Do not exceed the maximum load capacity of the balancer to prevent accidents. Buffering effect: Lengthened and thickened rubber sleeve, anti-collision buffer, equipped with safety lock, reduces buffer force, safe to use. Thickened hook: Alloy steel anti-fall hook, high-strength alloy steel forged hook, strong load-bearing, safe to use. Application: Retractable spring balancer are designed to support and balance tools or equipment, making it easier for users to operate them without feeling their full weight. They are often used in automotive, manufacturing, construction, and warehouse applications to suspend drills, pneumatic tools,s and other heavy equipment that needs to be easily accessible and movable, Manufacturer: VDCVADKYE
