This spring balancer is designed to suspend tools or equipment, making them easier to handle. It features an adjustable tension mechanism that allows users to fine-tune the supporting force to match the weight of the attached tool.

This load balancer pulls heavy objects using the spring force of a spring wire. The spring lines used in the retractor are reinforced to prevent deformation.

Air casters utilize kinetic energy to move heavy loads. These pneumatic lifting devices use compressed air to create a thin film of air, allowing for smooth movement.
