SQ08ZA3+1 Crane on a Flat Deck Truck in Tunisia

A small yellow crane folded at the front of a flat deck, behind a yellow mesh guard, on a truck parked in a narrow covered yard: a photo from our customer in Tunisia shows a BOB-LIFT SQ08ZA3+1 fitted to a light flat deck truck.

What the photo shows

• The truck. The photo is taken from behind a light truck with a long, low flat deck in dark grey and a grey steel frame at the front.
• The crane. The yellow crane is fitted at the front of the deck, folded upright with its hoses along the boom.
• The guard. A yellow mesh guard stands across the deck in front of the crane, between the crane and the load area.
• The place. The truck is parked in a narrow covered yard between a wall and a building, beside a rack of steel tubes.

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

SQ08ZA3+1 specifications

The SQ08ZA3+1 is an 800 kg knuckle boom crane with a maximum lifting moment of 1.3 t·m. The "+1" marks one extra boom section on top of the three-section SQ08ZA3. 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 SQ08ZA3+1 lifts 800 kg at 1.34 m but only 220 kg at 4.15 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 full 800 kg is rated only close to the column, at 1.34 m. At 2.25 m it is 450 kg, and at the full 4.15 m reach it is 220 kg.

The SQ08ZA3+1 product page has the full drawings. The same model is fitted to a service truck and a pickup in our delivery record from Indonesia, and built into a trailer in our record from Australia.

An 800 kg crane on a flat deck truck

On a light flat deck truck, a small crane at the front of the deck loads and unloads the items that are too heavy to lift by hand. Four things to plan for:

1. A guard for the crane. A guard between the crane and the load area, like the yellow mesh in the photo, helps stop loads from sliding into the crane when the truck brakes.
2. Reach down the deck. The rating falls fast with reach: 800 kg at 1.34 m, 300 kg at 3.23 m and 220 kg at 4.15 m. On a long deck, land the heavy items near the crane and keep light ones at the rear.
3. Room for the outriggers. The outriggers span 2,430 mm. In a narrow yard like the one in the photo, check there is room on both sides before you lift.
4. Fold it for the road. Fold the crane fully and stow the outriggers before the truck moves.

Other light cranes are in the pickup crane range, and every model up to about 1 t is listed on the 1 ton crane page. How we fit cranes to customer chassis is on the mounting and shipping page.

Checking a truck for the SQ08ZA3+1

Before you order, check three things on your truck. They decide whether the SQ08ZA3+1 fits it.

• Payload. The crane weighs 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 8 L/min at 18 MPa, about 3.5 kW. The power take-off and pump on your truck must give at least this.
• Outrigger room. The outriggers span 2,430 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.
