A yellow telescopic boom raised high over a green tandem-axle truck: a video from our customer in Indonesia shows a BOB-LIFT SQ5SA3 telescopic crane being worked in an industrial yard.

What the video shows

• The truck. A green truck with two rear axles carries a high-sided dropside body, with yellow-and-black stripes on the rear guard. The body is loaded with black steel frames.
• The crane. The yellow crane is mounted behind the cab. Its boom is raised steeply and extended, with a yellow hook block hanging on several falls of wire rope.
• The crew. Workers in coveralls and safety helmets stand beside the truck, and one crouches by the rear wheels.
• The movement. Later in the video the boom is lowered and slewed out toward a warehouse with a steel canopy, where gas cylinders stand along the wall.

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

SQ5SA3 specifications

The SQ5SA3 is a 5 t telescopic boom truck-mounted crane with a maximum lifting moment of 12.5 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 SQ5SA3 lifts 5,000 kg at 2.5 m but only 1,100 kg at 8.68 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 3.66 m from the slewing centre the crane is rated for 2,800 kg; at full reach it is 1,100 kg.

The SQ5SA3 product page has the full drawings. The four-section SQ5SA4 gives more reach in the same 5 t class. The same SQ5SA3 handles containers and recovery work in our delivery record from Uruguay and appears in our record from the Philippines.

Working a telescopic crane in a busy yard

The video was shot in a yard with people, parked tankers and a warehouse close to the truck. In a space like this, the boom moves over people and structures. Three things to plan for:

1. Keep people clear of the boom. When the boom is raised or slewed, it passes over the area around the truck. Keep the crew out from under the boom and the hook block, even with no load on the hook.
2. Check overhead before slewing. Canopies, roof edges and building fronts can be close. Check the clearance before slewing toward them, and watch the boom tip as it runs out.
3. Outriggers before the boom moves. Set the outriggers on firm ground before raising the boom, even for a test with an empty hook. They span 2,260 to 5,100 mm.

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 SQ5SA3

Before you order, check three things on your truck. They decide whether the SQ5SA3 fits it.

• Payload. The crane weighs 2,100 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 32 L/min at 20 MPa, about 18 kW. The power take-off and pump on your truck must give at least this.
• Outrigger room. The outriggers span 2,260 to 5,100 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.
