SQ16SA5 Telescopic Crane on a Building Site in Thailand

A yellow and dark blue telescopic boom raised high over a building site, with a concrete panel on a four-leg chain sling: three photos from our customer in Thailand show a BOB-LIFT SQ16SA5 telescopic crane on a three-axle cargo truck.

What the photos show

• The truck. A cab-over truck with a cream and maroon cab and three axles carries a tall slatted cargo body. The crane stands between the cab and the body.
• The crane. The lower boom sections are yellow, marked BOB-LIFT and SQ16S, and the upper sections are dark blue. The operator sits in a high seat on the crane column.
• Lifting precast concrete. On a building site, the boom is raised steeply and a four-leg chain sling hangs from the hook to a flat concrete panel. Precast concrete wall units stand in the background.
• Outriggers. The outriggers are out on both sides, including a long beam at the rear, with the feet on the ground.
• Overhead line. In two photos a power line runs across the site near the raised boom.

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

SQ16SA5 specifications

The SQ16SA5 is a 16 t telescopic boom truck-mounted crane with a maximum lifting moment of 40 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 SQ16SA5 lifts 16,000 kg at 2.5 m but only 1,050 kg at 22.3 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 10.1 m from the slewing centre the crane is rated for 4,100 kg; at 14.2 m it is 2,600 kg.

The SQ16SA5 product page has the full drawings, and every model around 16 t is on the 16 ton crane page. The 14 t SQ14SA5 works on a truck in our delivery record from Russia, and a 10 t knuckle boom crane works with a grab in our record from Thailand.

Lifting near overhead power lines

A 16 t telescopic crane reaches over 20 m into the air, and a building site often has power lines at that height. Contact or arcing can kill the operator and anyone touching the truck. Four rules to follow:

1. Find the lines before setting up. Walk the site, note every overhead line and its voltage, and place the truck so the boom never has to swing toward them.
2. Keep the minimum distance. OSHA's power line safety rule sets 20 ft (about 6 m) for lines up to 350 kV, unless the utility confirms a lower voltage. Local rules may ask for more.
3. Use a spotter. From the high seat it is hard to judge the gap between the boom tip and a line. A dedicated signal person should watch only that gap.
4. Ask for the line to be switched off. When the work must come closer, the utility can de-energise and ground the line first.

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 SQ16SA5

Before you order, check three things on your truck. They decide whether the SQ16SA5 fits it.

• Payload. The crane weighs 6,600 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 80 L/min at 30 MPa, about 55 kW. The power take-off and pump on your truck must give at least this.
• Outrigger room. The outriggers span 2,300 to 8,000 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.
