Reach Stacker Inspection & Certification in Dhahran
A reach stacker is a heavy mobile machine with a telescopic boom and a rotating top-lift spreader that picks up, stacks and transports ISO containers, and can place them in the second or third row. Reach stackers are used in Saudi ports, dry ports, container depots and logistics yards where a typical laden lift is tens of tonnes. A fault in the boom, spreader or twistlock mechanism can drop a laden container, so periodic third-party inspection and load testing are routinely required by terminals and shipping clients.

Testing
A load test is typically carried out with certified test weights or a weighted container at 100% of the rated capacity, and in some cases up to 110% or 125% depending on the standard and client. The test covers lift and lower at several chart positions, spreader rotation, load-sensing alarms and braking.

FAQs
Can you inspect a reach stacker on site in Dhahran?＋

Which industries in Dhahran request reach stacker inspection?＋

What is the difference between a reach stacker and a container handler?＋
A reach stacker uses a telescopic boom to reach over the first row and stack containers in the second row or above. A container handler is a mast-type truck that picks up and stacks containers directly in front of the machine.
Should the spreader be inspected separately from the reach stacker?＋
Yes. The spreader is a lifting device in its own right, with twistlocks, interlocks and structural parts that need specific checks. A competent inspector examines it as part of the reach stacker inspection, with its own findings recorded.
