SQ1ZA3 Crane on a White Dropside Truck in the Philippines

A yellow knuckle boom crane behind the cab of a white truck with a white dropside body, outriggers down, while a man works the control levers: photos from our customer in the Philippines show a BOB-LIFT SQ1ZA3 knuckle boom truck-mounted crane at handover.

What the photos show

• The crane. The yellow crane stands between the cab and the body. Its inner boom carries the marking SQ1Z, and a red hook hangs from the boom tip.
• The controls. A bank of control levers sits on the crane base at the side of the truck. In one photo a man in a grey T-shirt works the levers while others watch.
• The outriggers. A yellow outrigger leg on each side is lowered to the ground next to the crane base.
• The body. Behind the crane is a white dropside body with a tall white headboard frame.
• The setting. Two photos are taken inside a workshop with a steel roof, and one outside in a yard under a clear sky.

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

About the SQ1ZA3

The SQ1ZA3 is an earlier 1 t knuckle boom truck-mounted crane. It is no longer in the current range, and the technical department has no current drawing for it, so this record does not quote load figures for it. For a new crane of this size, see the 1 t knuckle boom truck-mounted crane page, where each current model has its own dimension and load chart drawings.

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, a load the crane lifts easily close to the column can be too heavy once the extension is pushed out. Outrigger span is the distance between the outrigger feet. A wider span keeps the truck steadier when the crane slews to the side. For general crane safety rules, see the OSHA cranes and derricks standard.

Lever controls on the crane base let the operator stand beside the load and watch it all the way. An SQ1ZA3 sits behind the cab of a blue light truck in our delivery record from Vietnam, and two 3.2 t cranes work on dropside trucks in our other record from the Philippines.

Handing over a new truck crane

The first day with a new crane sets the habits the crew will keep. Four points to cover at handover:

1. Learn the lever layout. Each lever drives one motion. Walk through every lever with the boom folded before the first real lift.
2. Set the outriggers first. Lower both legs onto firm ground before the boom leaves its rest, and raise them only after it is stowed again.
3. Read the load chart. Find the load chart plate on the crane and check where the rated load drops as the boom reaches out.
4. Practise stowing the boom. Fold the boom and hook the same way each time, so the folded height stays inside the cab line on the road.

Other sizes are in the knuckle boom truck-mounted crane range, and the mounting and shipping page explains how mounting is handled.

Checking a truck for a 1 t crane

Before you order a current 1 t crane, check three things on your truck. They decide whether the crane fits it.

• Payload. The crane, its subframe and the outriggers all come off the truck's payload. Plan the body and the loads you carry with what is left.
• Hydraulic power. The power take-off and pump on your truck must give the flow and pressure the crane needs.
• Outrigger room. Make sure the frame has room for the outriggers, and that your job sites do too.

If you run an SQ1ZA3 today, a photo of its nameplate helps us. Send the make, model and wheelbase of your truck through the contact page, and our team will check the fit.
