ARO Spring Balancers are equipped with worm screw adjustment and a locking/unlocking system. The casings and covers are made of a composite material for XS sizes and of cast aluminium for other sizes providing them with high shock resistance. The drums have tapered wire feeders and the cable is insulated. Safety is ensured by a spring protection and by locking of the drum should the spring break. 31 ARO spring balancer capacities are available from 2.7 to 168 kg.
Models with capacities greater than 35 kg are equipped in addition with a swivel, a safety chain and an encapsulated spring.
