SQ3.2SA3 Telescopic Cranes on Light Trucks in Thailand

A yellow telescopic crane holding a large container over a bare truck chassis: photos from our customer in Thailand show BOB-LIFT SQ3.2SA3 telescopic cranes on two light trucks, a white cab-chassis and an orange dropside truck.

What the photos show

• On the cab-chassis. Two photos show the crane behind the cab of a white light truck with a bare chassis. In one it holds a large white container in a yellow frame out to the side. In the other the boom is extended back over the chassis with the hook block hanging, while two men walk beside the truck.
• On the dropside truck. Two photos show the same crane model behind the cab of an orange Hino 300 with an orange dropside body. On the road the boom lies flat along the body, its tip on a rest at the rear.
• Markings. The yellow boom carries the BOB-LIFT name and the SQ3.2S marking.
• Outriggers. A yellow outrigger leg stands beside the cab.

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

SQ3.2SA3 specifications

The SQ3.2SA3 is a 3.2 t telescopic boom truck-mounted crane with a maximum lifting moment of 7 t·m and three boom sections (one main boom and two hydraulic 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 SQ3.2SA3 lifts 3,200 kg at 2.2 m but only 550 kg at 8.3 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 3.5 m from the slewing centre the crane is rated for 1,900 kg. At 5.9 m it is 800 kg, and at the full 8.3 m reach it is 550 kg.

The SQ3.2SA3 product page has the full drawings. The four-section SQ3.2SA4 reaches further in the same 3.2 t class. The larger three-section SQ5SA3 appears in our delivery record from Uruguay.

A telescopic crane on a light truck

The orange truck in the photos carries the crane with its boom laid along the body. On a light truck the crane weight and the stowed boom both need planning. Three things to check:

1. Stow the boom on a rest. Retract the boom fully and lower it onto a rest at the rear of the body before driving, as on the orange truck. With the boom retracted, the drawing gives 3.34 m from the column to the boom tip, so the rest has to sit at the right point on the body.
2. Count the crane in the payload. The crane weighs 1,280 kg. On a light truck that is a large share of the payload, so plan the body and loads with what is left.
3. Lift known weights against the chart. The full 3,200 kg is rated only at 2.2 m. At 3.5 m it is 1,900 kg, and at 5.9 m it is 800 kg. Know the weight of each load before you lift it.

Other capacities are in the telescopic boom truck mounted crane range, and every model around 3 t is listed on the 3 ton crane page. How we fit cranes to customer chassis is on the mounting and shipping page.

Checking a truck for the SQ3.2SA3

Before you order, check three things on your truck. They decide whether the SQ3.2SA3 fits it.

• Payload. The crane weighs 1,280 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 20 MPa, about 14 kW. The power take-off and pump on your truck must give at least this.
• Outrigger room. The outriggers span 1,720 to 3,120 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.
