(1) Marine Loading Arm
FB Type --- The loading arm is full balanced in all positions with two independent counterweight systems. It is a self-support structure，the pipeline and the swivel joint endure not only the pressure from the media but also the gravity and the overturn moment of all load. It is usually used on the river wharf and the small tanker.
--- RC Single Pipeline
This is a typical rotary counterweight marine loading arm. All of the vertical load and overturn moment should be supported by the base riser and supporting device to make the pipeline and the swivel joints be free in theory.
It can be manoeuvred neatly by hydraulic cylinder in three directions, and the balance system consist of a pantograph for transmitting balancing loads from the outboard arm to the secondary counterweight.
RC Single Pipeline FB Type
(3) Marine Loading Arm --- RC Double Pipeline
It incorporates a vapor line to carry the return vapor to the outlet flange. Other parts are same with the s i n g l e p i p e l i n e a rm .
It mainly be used to transit the LPG and ammonia and some dangerous media.
The trunnion assembly
is detachable easily
ERS (Emergency Release System)
The ERS manufactured by us mainly consists of three parts: the alarm system, hydraulic control system and release coupler
1) The alarm system consists of position switch and visual-audio annunciator
2) Hydraulic control system consists of accumulator, hydraulic control valve and hydraulic cylinder
3) The release coupler consists of shut off valve (double ball valve), clamping mechanism and pressing pole mechanism.
Patent No. ZL0172472.6
For double-line loading arm, both the vapor line and liquid line must be mounted with the ERS. In this picture, the ERS for the vapor line is different with the one for the liquid, it is only a single direction shut off valve. The structure is simple than ERC for liquid line. And while releasing, the two ERS shall be actuated synchronously.
Double Pipeline ERS
DDV/ERC & DBV/ERC
When the arm approaches the limit of the pre-determined working range ( i.e. the angle between inboard and Outboard arm≥ 135°)
First alarm, intermittent audio and light alarming
Sequentially a signal trans to operator to stop the pump.
Valve closing and draining valve opening.
When the arm approaches the limit of maximum operating envelope
( i.e. the angle between inboard and Outboard are≥ 150°)
Second alarm, continuously audio and light alarming
Opening of the ERC,the arm is hydraulically braked in position.

Model Application
Hydraulic QC/DC Introduction
The QC/DC could cancel the converging tube between
loading arm and vessel. And it can cover 3 nominal
dimension flange to make the connecting operation easily.
It makes the connect and disconnect au- tomatically with
hydraulic control system instead of manual operating.
