What the photos show

• The truck. A truck with a blue cab carries a yellow box body with windows, two doors and the word АВАРІЙНА (emergency) in red. Behind the body is a short grey flat deck with drop sides.
• The crane. The red crane is mounted at the rear corner, behind the box body. Its boom has an extension and a hook on a chain.
• The outriggers. Red and white striped outrigger legs are set down at the rear before the lift.
• The lift. The crane lowers a concrete block onto the rear deck. Workers in orange high-visibility vests stand around the truck.

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.

A rear-mounted crane leaves the box body free for crew and tools and serves the short deck behind it. An SQ1ZA3 sits behind the cab of a light truck in our delivery record from Vietnam, and a 3.2 t crane works on a dropside truck in snow in our record from Russia.

A crane on an emergency service truck

An emergency crew needs to arrive with tools, parts and a way to lift them. A rear-mounted crane does that on a single truck. Four points to plan for:

1. Plan the rear layout. The crane, the outriggers and the deck all share the back of the truck. Make sure doors and steps on the body stay clear.
2. Set up on uneven ground. Emergency jobs are rarely on level ground. Use outrigger pads and level the truck before each lift.
3. Keep the crew out of the swing area. Mark off the area behind the truck so no one stands under a load or between the block and the deck.
4. Check the crane before each call-out. Look over hoses, the hook and the outriggers so the crane is ready when the truck is needed.

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.
