SQ3.2ZA3 Knuckle Cranes Fitted on Trucks in Thailand

Five photos from our customer in Thailand follow SQ3.2ZA3 knuckle boom cranes through a truck workshop: yellow cranes being fitted behind white cabs, and one finished red truck whose crane was painted to match and carries the customer's own brand on the boom.

At a glance: SQ3.2ZA3 3.2 t knuckle boom crane · Thailand · behind-cab on light trucks with dropside bodies · 5 customer photos · one unit supplied in the customer's colour and brand.

What the photos show

• Fitting in the workshop. A yellow crane stands behind the cab of a white truck while the steel cargo body is still being built. The BOB-LIFT and SQ3.2Z markings are on the boom, and the yellow oil tank sits on the side of the crane base.
• Folded behind the cab. Another white truck has its crane folded upright between the cab and a dropside body still in primer, with the battery box mounted below the crane base.
• On the chassis. In a wide steel-framed shop, technicians work around a yellow crane on a chassis with the cab tilted forward and the engine exposed.
• The finished red truck. Parked outside an office building, a red light truck with a dropside body carries a red crane. The boom shows the SQ3.2ZA3 model code next to the customer's own brand name, which we have masked in the photo.

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.

Folded, the crane sits within the cab width, which keeps a light truck like these easy to drive and park in town. Unfolded, it is rated for 1,350 kg at 4.35 m and 680 kg at its full 7.7 m reach.

The SQ3.2ZA3 product page has the dimension drawing and the full specification. The same model, painted to match a whole fleet, is in our delivery record from Sudan.

Ordering cranes in your own colour and brand

A dealer or body builder who sells under its own name can order the crane to fit that name. Three things to agree before production:

1. Colour. Send the paint code with the order. The red crane in these photos was painted to match the truck it went on, while the others kept the standard yellow.
2. Markings. Agree which brand name goes on the boom. The model code and the load chart stay those of the SQ3.2ZA3, so the rated loads in the table above still apply.
3. Mounting layout. The crane weighs 1,330 kg and needs about 850 mm behind the cab. Fix one subframe and hydraulic layout for each chassis type you build on, and repeat it.

Whatever the paint and name, keep the load chart and the warning labels on the crane where the operator can read them. 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.
