SQ5SA4 Telescopic Crane on an IVECO 6x6 in Kenya

A red telescopic boom marked SQ5S behind the cab of a blue 6x6 dropside truck, lifting a white machine onto its own deck: photos and a video from our customer in Kenya, an engineering machinery, mining and support services company, show one of the five BOB-LIFT SQ5SA4 telescopic cranes they run on their own IVECO T-WAY 6x6 trucks.

At a glance: SQ5SA4 5 t telescopic boom crane · Kenya · 5 cranes on the customer's IVECO T-WAY 6x6 trucks · 3 customer photos and a 56-second video. The customer told our sales team they are very satisfied and are planning a second batch.

What the photos and video show

• The truck. A blue IVECO T-WAY 6x6 with a long dropside deck. The crane stands between the cab and the deck, and a fleet number is stuck on the windscreen. The truck is the customer's own; BOB-LIFT supplied the crane.
• The crane. The red boom carries the BOB-LIFT logo and the SQ5S series mark used on our 5 t telescopic cranes.
• Outriggers. In each photo the near-side outrigger is out and set down on a solid pad before the lift.
• Hydraulics. A black hydraulic oil tank with a level gauge is fitted next to the crane column.
• The lift. In the video the operator stands at the control station beside the outrigger. A white machine is lifted on chain slings from the ground behind the truck, slewed round and set down on the rear of the deck. The boom is raised and only partly extended, so the load stays at a short radius.

These are the customer's own photos and video. No load weights or dates came with them. The customer's company name is not given here.

SQ5SA4 specifications

The SQ5SA4 is a 5 t telescopic boom truck-mounted crane with a maximum lifting moment of 12.5 t·m and four boom sections. The figures below are read from the technical department's drawing and load chart.

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 full 5,000 kg applies only at about 2.2 m with the shortest boom raised to 50°, while at the full 11.8 m reach the crane is rated for 600 kg. Outrigger span is the width between the outrigger feet when they are fully out. Set them on firm, level ground or solid pads, as in these photos, before each lift. For ground and outrigger rules, see the OSHA cranes and derricks standard.

With the boom level, the crane is rated for 3,000 kg at 4.0 m and 1,650 kg at 6.6 m. That is why the lift in the video, close to the truck, sits well inside the chart.

The SQ5SA4 product page has the full drawings, and our news story Five SQ5SA4 telescopic truck cranes at work for a Kenyan mining services company has the photos and the full video. The three-section SQ5SA3 in the same 5 t class appears in our delivery record from the Philippines.

A service truck that loads itself

For machinery and mining support work, the crane turns the truck into a vehicle that loads and unloads its own deck: pumps, compressors, generator sets, spares and tool boxes go on at the yard and come off on site without waiting for a separate crane. Four points to plan for:

1. Read the chart at the set-down point. Check the rated load at the farthest point the load must reach, such as the rear of a long deck, not the 5 t headline figure.
2. Pad every outrigger. Mine and yard ground is often loose or soft. Our article on crane outriggers and ground bearing pressure shows how to check it.
3. Hard hats and a clear zone. The operator and anyone guiding the load should wear a hard hat, and nobody should stand under the load or between it and the deck while it is landed.
4. One model across the fleet. With five identical cranes, operators learn one control layout and one load chart, and the workshop stocks one set of seals, hoses and wear parts.

Other capacities are in the telescopic boom truck mounted crane range, and every model around 5 t is listed on the 5 ton crane page.

Checking a truck for the SQ5SA4

Before you order, check three things on your truck. They decide whether the SQ5SA4 fits it.

• Payload and space. The crane weighs 2,400 kg and needs 800 mm behind the cab. Take its weight off the truck's payload, then plan the deck and the loads you carry with what is left.
• Hydraulic power. The crane needs 32 L/min at 21 MPa, about 18 kW. The power take-off and pump on your truck must give at least this.
• Outrigger room. The outriggers span 2,293 to 5,593 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.
