SQ8SA5 8 t Telescopic Crane on a KAMAZ in Russia

An orange KAMAZ 43118 three-axle truck with a blue dropside body carries a red BOB-LIFT SQ8SA5 telescopic crane behind its cab. Six photos from our customer in Russia show the finished truck in an industrial yard. They run from the full side view down to the control levers.

The finished truck

• Chassis and body. The cab door carries the 43118 badge. The truck runs on large all-terrain tyres, and its long blue dropside body has a yellow stripe along the sides.
• Crane in transport position. The column stands directly behind the cab, and the folded boom rests above the front of the body. The boom carries the BOB-LIFT and SQ8S markings.
• Controls. A close-up shows a pressure gauge at the control station. Next to the outrigger levers a Russian-language decal marks the vertical and horizontal outrigger legs and the right and left sides.
• Column and hydraulics. Two shots from beside the cab show the column, the slewing housing and the hose runs. The red outrigger beam sits under the crane base.
• Site. The truck stands on bare ground among brick industrial buildings under a clear sky. No load is on the hook in any photo.

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

SQ8SA5 specifications

The SQ8SA5 is an 8 t telescopic boom truck-mounted crane with a maximum lifting moment of 20 t·m and five boom sections. 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 SQ8SA5 lifts 8,000 kg at 2.5 m but only 400 kg at 18.5 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 five-section boom is what gives this model its 18.5 m reach. Out there it is rated for 400 kg; at 8.5 m, roughly the far corner of a long body, it is rated for 1,800 kg.

The SQ8SA5 product page has the dimension drawing and the full specification.

Fitting an 8 t telescopic crane to a heavy three-axle chassis

A three-axle chassis like this one has the payload and frame strength for a crane in this class. Three checks still decide the build:

1. Front-axle load. The crane alone weighs 4.1 t, and almost all of it sits just behind the cab. Add the subframe and check the front-axle rating before choosing the body length.
2. Space behind the cab. The SQ8SA5 needs about 1,100 mm of installation space, which comes off the length available for the body.
3. Power take-off. The crane is specified for 55 L/min at 26 MPa, about 30 kW. The gearbox PTO and pump need to deliver that at a steady engine speed.

Fully extended, the outriggers span almost 6 m. Plan lift positions so that width is clear and the ground under both feet is firm. How we plan the subframe and fit a crane to a customer chassis is on the mounting and shipping page. Other capacities are in the telescopic boom truck mounted crane range.

Checking a truck for the SQ8SA5

Before you order, check three things on your truck. They decide whether the SQ8SA5 fits it.

• Payload. The crane weighs 4,100 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 55 L/min at 26 MPa, about 30 kW. The power take-off and pump on your truck must give at least this.
• Outrigger room. The outriggers span 2,290 to 5,990 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.
