SQ1ZA3T Pedestal Crane Lifting a Tank in the Philippines

An orange knuckle boom crane with an operator's seat high on its column, swinging a white cylindrical tank on chains: a video from our customer in the Philippines shows a BOB-LIFT SQ1ZA3T knuckle boom crane at work.

What the video shows

• The crane. The orange crane stands on a square concrete pedestal. The operator sits in a seat fixed high on the column and works the levers from there.
• The lift. A white cylindrical tank hangs from the hook on chains. The crane raises it, slews it round and sets it down, then the boom swings back with the extension pushed out.
• The boom. In the second half of the video the extension section runs out to its full length while the operator moves the boom.
• The site. The pedestal stands at the edge of a paved yard, behind a low wall with a railing and palm trees.

This is the customer's own video. No load weights, dates or comments came with it.

About the SQ1ZA3T

The SQ1ZA3T is an earlier 1 t knuckle boom marine crane. It is no longer in the current range, and the technical department has no current drawing for it, so this record does not quote load figures for it. For a new crane of this size, see the 1 t knuckle boom marine crane page, where each current model has its own dimension and load chart drawings.

Lifting moment is the load times its distance from the slewing centre. That is why the rated load drops as the boom reaches out. For example, a load the crane lifts easily close to the column can be too heavy once the extension is pushed out. Working radius is the level distance from the slewing centre to the hook. On a vessel or a quay, the pedestal takes the place of outriggers. It must be strong enough for the crane's weight and its full lifting moment. For general crane safety rules, see the OSHA cranes and derricks standard.

A high seat on the column lets the operator see the load over the pedestal and the wall. An SQ1ZA3T works on a vessel in our delivery record from the Netherlands, and a truck crane with a high seat works in our other record from the Philippines.

Lifting tanks with a pedestal crane

Tanks and drums are awkward loads: they are heavy for their size, and they swing and turn on the hook. Four points to plan for:

1. Know the tank weight. Check whether the tank is empty or holds liquid before you lift. A partly filled tank shifts its weight as it moves.
2. Rig at proper lifting points. Use the tank's lifting lugs and chains or slings rated for the load, so the tank hangs level.
3. Keep the area clear. No one should stand under the tank or in its swing path while it moves.
4. Watch the reach. With the extension out, the rated load is much lower. Plan each lift against the load chart for that radius.

Sea water is hard on steel, so the marine cranes get an epoxy zinc primer with a polyurethane acrylic top coat. Other capacities are in the knuckle boom marine crane range, and the marine crane buying guide covers pedestal and deck mounting in more detail.

What to send us for a marine crane

To match a current crane to your site, we need a few details. Short answers are fine.

• The site. The vessel type and length, or the quay, and where the crane will stand.
• The lifts. The heaviest load, and how far from the crane it is picked up and set down.
• The power. The hydraulic power pack you have now, or whether you need a new one.

If you run an SQ1ZA3T today, a photo of its nameplate helps too. Send these through the contact page, and our team will check reach and load against the current load charts.
