Variable Reach Top Loading Arm
The model 621-BC/721-BC variable reach top loading arm is the most commonly used loader for top filling road tankers. This is due to its variable operating range, allowing multiple tanker compartments to be filled without the need to re position the truck. We offer two models of variable reach top loading arm 621-BC for high use/volume and 721-BC for low use/volume.
This model of top loading arm design includes, four swivel joints for horizontal and vertical positioning, a compression spring balance cylinder for ease of movement, loading valve with either hold-open or stay-open operation, extension/remote control for outboard loading valve operation, fitted with a vacuum breaker to allow fast drainage.
