SQ6.3SA4 Crane Lifting a Borehole Pump in Cyprus

A pump column hanging straight down from the hook, its riser pipe wrapped in white tape and the power cable running beside it: three photos from our customer in Cyprus show an SQ6.3SA4 telescopic crane, repainted in the owner's yellow and blue, lifting a borehole pump at a house.

On the job in Cyprus

• The truck. A white light truck with an 816 badge on the door and a dropside body. The crane has been repainted yellow, with dark blue extension sections, and the owner's company name and phone number run along the boom and across the rear of the body.
• Set up in a garden. One photo shows the truck parked on a lawn beside a paved path, with the boom raised steeply over the trees and lengths of pipe laid out on the path.
• Boom up in a street. Another photo, taken from a balcony, shows the boom raised high above a residential street lined with palm trees, with the hoist winch on the side of the boom base.
• The lift. The close-up shows the pump assembly on a single line from the boom tip: the stainless pump at the bottom, the taped riser pipe above it and a flange at the top, hanging above a concrete wellhead enclosure.

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

SQ6.3SA4 specifications

The SQ6.3SA4 is a 6.3 t telescopic boom truck-mounted crane with a maximum lifting moment of 15.75 t·m and four 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 SQ6.3SA4 lifts 6,300 kg at 2.5 m but only 600 kg at 12.6 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.

With the boom raised steeply, as in these photos, the hook stays close to the truck, where the rating is highest: 6,300 kg at 2.5 m and 2,800 kg at 4.5 m.

The SQ6.3SA4 product page has the dimension drawing and the full specification. The same model on a ramp flatbed is in our delivery record from Congo.

Using a telescopic crane for borehole pumps

Pulling or setting a borehole pump is a vertical lift: the pump and riser come straight up out of the well, often in long sections. That makes hook height more important than reach. Three points to plan:

1. Height under the hook. The SQ6.3SA4 reaches about 14.5 m at the tip. Subtract the hook block and slings to find the longest pipe section you can lift clear of the wellhead in one piece.
2. Radius to the wellhead. Park so the well is as close to the column as the site allows. The rating drops from 2,800 kg at 4.5 m to 1,500 kg at 7.2 m, and a full pump string of pipe, water and cable is heavier than the pump alone.
3. Outriggers on garden ground. The outriggers span up to 5.3 m. On a lawn or a paved path, use pads under the feet and check the ground before raising the boom.

How we fit cranes to customer chassis is on the mounting and shipping page, and other capacities are in the telescopic boom truck mounted crane range.

Checking a truck for the SQ6.3SA4

Before you order, check three things on your truck. They decide whether the SQ6.3SA4 fits it.

• Payload. The crane weighs 2,600 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.
