SQ3.2ZA3 Knuckle Cranes for a Truck Fleet in Sudan

A long row of SQ3.2ZA3 knuckle boom cranes in sand-coloured paint, still in their shipping film, stands inside a warehouse: three photos from our customer in Sudan follow the batch from delivery to a crane fitted on a truck and lifting an engine block in a workshop.

What the photos show

• The delivery. The folded cranes stand side by side on a warehouse floor, each wrapped in clear film, with the BOB-LIFT and SQ3.2Z markings visible through the plastic.
• Fitted behind the cab. A close-up shows one crane mounted between the cab and the slatted cargo body of a sand-coloured truck, painted to match it. The column, the lift cylinder and the folded booms sit just behind the cab door.
• Lifting an engine. In a large workshop, the crane on a three-axle off-road truck lifts a V-type engine block on chains beside the truck's body. More off-road trucks are parked across the workshop floor.

These are the customer's own photos. No lift 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. 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.

The engine in the workshop photo hangs close to the truck, where the SQ3.2ZA3 is rated for up to 3,200 kg at 2.1 m and 1,350 kg at 4.35 m.

The SQ3.2ZA3 product page has the dimension drawing and the full specification. The same model lifting a trailer is in our delivery record from the United States.

Planning a fleet order of the same crane

When several trucks of one type get the same crane, the work is done once and repeated. Three points to settle before the cranes leave the factory:

1. Paint colour. These cranes were painted to match the trucks they went on. Give us the colour code with the order, and every crane arrives in the same finish.
2. One mounting layout. The SQ3.2ZA3 needs about 850 mm behind the cab and weighs 1,330 kg. With identical chassis, one subframe and one hydraulic layout can be used for the whole batch.
3. Hydraulics. The crane is specified for 25 L/min at 25 MPa, about 14 kW. Check the power take-off on the first truck, then use the same pump and settings on the rest.

For workshop lifts such as engines and gearboxes, weigh the part or check its listed weight first, and lift on rated chains attached to the proper lifting points. 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.
