Spring Balancer Retractable Adjustable Tool Holder for Easy Loading Unloading, Ratchet Device Efficient Ergonomic Support Rope Hanging Holding Equipment, 5-9KG/11-20lb

The weight of the attached tool must be within the load range of the balancer. The products are divided into regular and self-locking versions Example 1: The weight of the device itself+the weight of the device accessories=total weight 1kg+1kg=2kg. Suggest choosing ZW1-3 (1-3kg) spring balancer. Example 2: Choose when the total weight is exactly the same as the upper limit of a certain type of balancer. The weight of the equipment itself+the weight of the equipment accessories=total weight 1kg+2kg=3kg. Suggest using ZW3-5 (3-5kg) spring balancer. This is because it is necessary to avoid the coil spring working at its upper limit, otherwise it may cause fatigue and affect its service life. If the coil spring is operated below the lower limit, it can improve its service life.
