Top loading truck and railcar systems are an efficient and cost-effective method of loading and unloading.
A top loading arm is designed to have sufficient horizontal range to reach the farthest compartment without re-spotting the vehicle. Vertical movement and drop-pipe lengths to service vehicles of varying heights are also necessary. A properly designed top loading arm can achieve this requirement. Top loading arms can also be used for tight-fill and vapor recovery applications.
A wide range of valves, fittings and instrumentation equipment is available for special top loading arm designs.
