SQ6.3SA3 Telescopic Crane on a 6x6 Truck in Russia

An orange crane behind the cab of an olive-green 6x6 truck, parked in the snow: photos from our customer in Russia show a BOB-LIFT SQ6.3SA3 telescopic crane mounted on an off-road dropside truck.

What the photos show

• The truck. An olive-green truck with a bonnet, three axles and large off-road tyres carries a dropside body with timber-lined sides.
• The crane. The orange crane stands between the cab and the body. The boom is marked BOB-LIFT and SQ6.3S, and the hook block has red-and-white stripes.
• Controls and outriggers. Close-ups show the control valve bank with its levers at the base of the column, an orange outrigger leg beside it, and a black box mounted on the side of the column.
• Boom out. In one photo the boom is extended back over the body, with the hook hanging.
• The setting. The truck stands in a snow-covered industrial yard, with workshops and other trucks around it and people standing beside it.

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

SQ6.3SA3 specifications

The SQ6.3SA3 is a 6.3 t telescopic boom truck-mounted crane with a maximum lifting moment of 15.75 t·m and three boom sections (one main boom and two hydraulic 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 SQ6.3SA3 lifts 6,300 kg at 2.5 m but only 1,200 kg at 8.62 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.

At 3.94 m from the slewing centre the crane is rated for 3,200 kg. At 6.4 m it is 1,800 kg, and at the full 8.62 m reach it is 1,200 kg.

The SQ6.3SA3 product page has the full drawings. The four-section SQ6.3SA4 gives more reach in the same 6.3 t class; it appears in our delivery record from Congo and our record from Cyprus. Another BOB-LIFT crane works through the Russian winter in our SQ3.2ZA3 record.

A telescopic crane in winter

The photos were taken in a snowy yard. Cold weather changes how the crane is set up and run. Three things to plan for:

1. Outriggers on snow and ice. Clear snow down to firm ground, or use wide pads. Packed snow and ice can shift under an outrigger foot. The outriggers span 2,280 to 5,300 mm.
2. Warm the hydraulics first. Run the power take-off and move the crane slowly with no load until the oil is warm. Then start lifting.
3. Check for ice before each lift. Look over the wire rope, the hook and the control levers. Keep snow off the levers and the outrigger controls.

Other capacities are in the telescopic boom truck mounted crane range, and every model around 6 t is listed on the 6 ton crane page.

Checking a truck for the SQ6.3SA3

Before you order, check three things on your truck. They decide whether the SQ6.3SA3 fits it.

• Payload. The crane weighs 2,280 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 40 L/min at 20 MPa, about 22 kW. The power take-off and pump on your truck must give at least this.
• Outrigger room. The outriggers span 2,280 to 5,300 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.
