SQ12SU2T Telescopic Crane on a Well Service Truck in Belarus

A white telescopic boom crane with the BOB-LIFT name on its boom, mounted on a well service truck and holding a blue frame with hoses above a steel stand: a photo from our customer in Belarus shows a BOB-LIFT SQ12SU2T crane at work on a fenced site in summer.

What the photo shows

• The truck. A white cab truck carries an operator cabin on a raised frame, a large blue reel with a yellow arm, steel stairs and yellow railings.
• The crane. The crane stands at the rear of the truck. Its boom has a white base section with the BOB-LIFT name and a dark grey extension, raised steeply.
• The lift. From the hook hangs a blue frame with hoses. It sits above a blue steel stand with red pipework inside, held steady by guy wires.
• The site. A worker stands on the truck's platform. The site is fenced with razor wire, and a brown tank truck stands on the right, next to a green field.

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

About the SQ12SU2T

The SQ12SU2T is an earlier 12 t telescopic boom truck-mounted crane with a two-section boom. 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 12 t telescopic 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 with the boom retracted can be too heavy once the boom is telescoped 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.

On a truck like this, the crane shares the frame with the reel and the cabin, so it has to fit into a crowded layout. A second crane from the same customer works on a well stand in our SQ8SU2T record from Belarus, and a 12 t telescopic crane works on a truck in our delivery record from Bahrain.

A crane on a well service truck

A service truck that brings its own crane can rig up and lift equipment over the stand without waiting for a separate mobile crane. Four points to plan for:

1. Plan the frame layout. The crane, the outriggers, the reel and the cabin all need space. Lay them out on paper before the truck is built.
2. Check the reach to the stand. Measure where the truck can park and how far the hook must reach to centre a load over the stand.
3. Watch the wind. A tall boom and a large frame on the hook catch the wind. Set a wind limit for the job and stop lifting above it.
4. Keep people clear of the load. No one should stand under the frame or inside the stand while it hangs on the hook.

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

Checking a truck for a 12 t crane

Before you order a current 12 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 equipment 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.
• Space on the frame. Make sure the frame has room for the crane and its outriggers next to the equipment already on the truck.

If you run an SQ12SU2T 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.
