Top Loading Arms
Increase safety with top loading arms integrated with fall prevention access equipment.
Let us design the best top loading arms for your application.
We serve the petroleum, chemical and food industries providing effective loading and unloading systems for the safe and efficient handling of all types liquids.
- A variety of swivel joints provide flexibility and leak free operations
- Easy operation
- Product compatibility with metals and seals
- Strong swivel/spring capacity allows longer arm reach
- Unparalleled range of motion (over 95 degree working range) means we reach more openings
- Spring can be adjusted in any position
Single Arm Fixed Reach
Primarily used to load and unload railcars through open domes in installations where the cars can be accurately spotted. The single arm configuration can also be used for tank truck applications. Some allowance for mis-spotting is possible with the single arm and increases as the diameter of the hatch opening increases.
This simple arm incorporates only three swivel planes of rotation and is designed for use in top loading installations where the vehicle is located at a fixed distance from the riser pipe. The two swivel planes at the inlet permit both up-and-down and side-to-side movement of the assembly, and the third swivel plane allows the drop pipe to remain vertical. Valves can be located inboard or outboard to facilitate loading. With a valve located outboard, drippage of viscous products after loading can be minimized.
The single arm loader is adaptable to tight fill or closed system loading when equipped with additional swivel planes of rotation and/or drop hose, along with required outboard coupling, union or fitting.
Adaptable to tight-fill or closed system loading when equipped with additional swivel planes of rotation and/or drop hose; along with required outboard coupling, union or fitting.
Scissor Type Arm
Commonly used to handle high flow rates and withstand rough usage in tank truck loading applications, the scissor arm is also an excellent choice for railcar loading installations where cars are frequently mis-spotted.
This versatile arm is designed specifically for top loading installations where a variable operating range is required. The secondary arm rotates 360 degrees in the horizontal plane, providing a spotting allowance of up to twice its length.
Note: The scissor arm configuration is not recommended in 6” size in stainless steel due to the difficulties an operator would have handling the heavy outboard components.
- Ideal for applications where spotting the vehicle is variable
- Adaptable to tight-fill or closed system loading when equipped with additional swivel planes of rotation and/or drop hose; along with required outboard coupling, union or fitting.
Supported Boom Arm
This style arm provides dependable, low maintenance service in high usage installations. Due to the boom-mounted design, no heavy loads are placed on the swivel components, so wear is minimized.
In simplest terms, the supported boom arm loader consists of a single-arm loader mounted on a swiveling boom that is attached to a permanent structure with either a pillow block or flange bearing for added strength and support. This configuration provides maximum flexibility for mis-spotting and longer reaches from the loading rack to the railcar or tank truck. Both the boom and the arm can be folded back against the rack for convenient, compact storage away from the traffic flow.
A variety of boom designs and configurations are available to meet the needs of virtually any installation. Used for tank truck and railcar open dome loading, supported boom arms can be modified for closed system loading and unloading.
Optional valves, such as dry disconnect, ball, butterfly or loading, can be used because of the boom support.
- Long reach
- Design flexibility means it can be used for any application
- Folded back on itself, it can be easily stored
- Optional valve and remote
Unsupported Boom Arm
The unsupported boom arm is an excellent alternative for variable reach applications, especially in larger sizes where the outboard components are relatively heavy. It can be modified for closed system loading and unloading, and is available in various design configurations to meet the needs of virtually any installation.
This popular style loader is designed for those installations where it is undesirable or impractical to mount a supported boom arm. For example, many railcar sites have no support columns or overhead structures to which a supported boom can be attached.
The unsupported boom arm offers the same advantages as the supported boom arm, but maximum reach is somewhat less. It provides good flexibility for mis-spotting, and can be folded back against the rack for convenient, compact storage. When necessary, increasing the size of the base joint, or using a heavy-duty split flange swivel at the inlet, can extend
- Optional valving allows liquid to be held in the line
- Long reach compensates for mis-spotting
- Compact storage
