What the photos show

• The mounting. The crane stands on the floor of the box body, just inside the rear opening. Its base is bolted down on a steel plate, and the hoses run down through a hole in the floor.
• The lift. In the first photo the boom reaches out of the back of the truck with its extension out. A large flat load wrapped in black hangs from the hook on two yellow webbing slings.
• Folded inside. In the second photo the crane is folded upright inside the box. A yellow push-button control box hangs on the column on its cable.
• The body. Wooden A-frame racks stand along the inside wall, and the walls carry tie-down rails and blue straps.

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

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 sits at the front of a flat deck in our delivery record from Tunisia, works on a service truck and a pickup in our record from Indonesia, and is built into a trailer in our record from Australia.

An 800 kg crane inside a box truck

Mounted inside the rear of a box body, a small crane can lift loads in and out through the back door while the body keeps the cargo covered. Four things to plan for:

1. Height inside the box. The folded crane has to fit under the roof of the body. Measure the inside height and send it to us with your order, so we can check the folded crane against it.
2. A strong floor. The crane's forces go into the floor where the base sits. The floor and subframe under the base need a steel plate, like the one in the photos, tied into the truck chassis.
3. Reach out of the door. A load swung out past the rear of the truck is already some way from the column. The rating there is 450 kg at 2.25 m and 300 kg at 3.23 m, not the full 800 kg.
4. Outriggers for every lift. The outriggers span 2,430 mm. Set them on firm ground before each lift, even for light loads, and stow them 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.
