SQ16SA5 Crane on a Flatbed Truck in Trinidad and Tobago

A yellow telescopic crane folded over the cab of a bonneted truck, with an outrigger down in front of the bumper: a photo from our customer in Trinidad and Tobago shows a BOB-LIFT SQ16SA5 telescopic crane on a two-axle flatbed truck.

What the photo shows

• The truck. A conventional-cab truck with a white bonnet and a black cab carries a yellow flat deck. A tank marked HYDRAULIC OIL hangs under the deck on the side, and the wheels are painted yellow.
• The crane. The yellow crane is mounted at the rear of the deck. Its boom is lowered and runs forward over the cab, marked BOB-LIFT, SQ16S and MADE IN CHINA, with a NO STANDING UNDER THE BOOM warning near the black extension sections.
• Hook and controls. The yellow-and-black striped hook block hangs from the boom tip in front of the truck. The control levers sit at the crane base, at the back of the truck.
• Outriggers. Outriggers are down at the rear, and an extra outrigger stands in front of the front bumper.
• The site. The truck stands on a concrete yard with fields and palm trees behind it.

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 same model lifts precast concrete in our delivery record from Thailand, and a 2 t telescopic crane works on an Isuzu truck in our record from Trinidad and Tobago.

A rear-mounted crane on a two-axle truck

Here the crane stands at the rear of the deck and its boom rests over the cab. This layout keeps the deck in front of the crane free for loads, but it changes how the truck is set up. Four points to plan for:

1. Use the front outrigger. When the boom slews over the cab, the front axle and springs take the load. The extra outrigger in front of the bumper, seen in the photo, carries it to the ground instead. Lower it before slewing forward.
2. Check the axle loads. A 6,600 kg crane at the rear puts most of its weight on the rear axle. Weigh the finished truck, with the boom stowed, and compare each axle with its rating.
3. Stow the boom for travel. Retract the boom fully, lower it onto its rest and secure the hook block so it cannot swing while driving.
4. Watch the load from the controls. At the rear controls the operator looks along the deck. For lifts beside the cab or in front of the truck, use a signal person.

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.
