SQ3.2ZA3 Knuckle Crane Lifting Bulk Bags in Indonesia

A generator set chained to a flat deck, and white bulk bags swung up onto a truck: a photo and a one-minute video from our customer in Indonesia show yellow BOB-LIFT SQ3.2ZA3 knuckle boom cranes on two different trucks.

What the photo and video show

• Generator on a flat deck. The photo shows a yellow crane, marked BOB-LIFT and SQ3.2Z, behind the green cab of a light truck with a steel flat deck. A blue enclosed generator set rides on the deck, held down with a chain and a yellow ratchet strap. The crane is folded behind the cab for the road.
• Bulk bags. In the video a second yellow crane, on a white truck, lifts large white bulk bags from the ground up onto the truck. The outriggers are down, and the crew wear blue hard hats and high-visibility shirts.

These are the customer's own photo and video. No load weights, dates or comments came with them.

SQ3.2ZA3 specifications

The SQ3.2ZA3 is a 3.2 t knuckle boom truck-mounted crane with a maximum lifting moment of 6.8 t·m and three boom sections (one main boom and two hydraulic booms). Reach and load figures are read from the technical department's load chart drawing; the hydraulic figures come from the BOB-LIFT brochure.

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, the SQ3.2ZA3 lifts 3,200 kg at 2.1 m but only 680 kg at 7.7 m. Outrigger span is the width between the outrigger feet when they are fully out. Set them on firm, level ground, such as concrete or compacted gravel, before each lift. For ground and outrigger rules, see the OSHA cranes and derricks standard.

At 4.35 m from the slewing centre the crane is rated for 1,350 kg; at full reach it is 680 kg.

The SQ3.2ZA3 product page has the full drawings. The same model lifts generator sets in our delivery records from Kuwait and Chile.

Lifting bulk bags with a 3.2 t crane

Bulk bags, also called FIBCs, carry powders and granules in loads of up to about a tonne. They are soft, they can swing, and the whole load hangs from the lifting loops. Before each lift:

1. Read the bag label. Every bulk bag has a safe working load printed on its label. Weigh or estimate the filled bag, then check the chart at the radius where it lands: the SQ3.2ZA3 is rated for 1,350 kg at 4.35 m and 910 kg at 5.9 m.
2. Use all the loops. Hook every lifting loop the bag maker intends, with a hook or spreader that holds them without twisting. A bag lifted by one loop can tear or tip its load.
3. Lift straight up. Bring the boom tip over the bag before lifting, so the bag does not drag or swing. Keep people out from under it, and let the crew on the deck guide it only once it is low.

For the road, the photo shows the other half of the job: a heavy load on a flat deck needs its own lashings, like the chain and ratchet strap on the generator. How we fit cranes to customer chassis is on the mounting and shipping page, and other capacities are in the knuckle boom truck mounted crane range.

Checking a truck for the SQ3.2ZA3

Before you order, check three things on your truck. They decide whether the SQ3.2ZA3 fits it.

• Payload. The crane weighs 1,330 kg. Take this off the truck's payload, then plan the body and the loads you carry with what is left.
• Hydraulic power. The crane needs 25 L/min at 25 MPa, about 14 kW. The power take-off and pump on your truck must give at least this.
• Outrigger room. The outriggers span 2,250 to 3,513 mm. Make sure the frame has room for them, and that your job sites do too.

Send us the make, model and wheelbase of your truck through the contact page, and our team will check the fit.
