A compact, simple-to-operate and safe hydraulic gantry crane is being introduced by Enerpac South-East Asia to facilitate precision lifting and positioning of heavy loads, up to 408 metric tons, when using four towers.

The SL-400 Super Lift Series is a cost-effective alternative to a traditional crane for numerous applications including building and infrastructure, manufacturing, mining, logistics, ports, oil and gas and maintenance.

The SL-400 hydraulic gantry is the company’s highest capacity bare cylinder gantry. Equipped with three stage lifting cylinders, the SL-400 lifts up to 9.14m at the top of the third stage and can handle up to 408 metric tons at the top of the second stage.

Designed to meet stringent safety requirements, the SL-400 complies with the safety standards set by ASME B30.1-2015. To ensure quality performance, each gantry is tested to 120 percent of capacity at full extension and witness tested by a qualified third party organization. The SL-400 is also CE compliant.

“The SL-400 has a smaller footprint compared with larger gantry cranes and overhead cranes, making it ideal for heavy duty lifting in confined spaces, limited hook approaches or low headroom areas, such as heavy machinery, turbine or generator positioning and press installation,” says Enerpac Integrated Solutions Manager for South-East Asia, Mr Maxim Lee.

Hydraulic Gantries are a safe, efficient way to lift and position heavy loads in applications where traditional cranes will not fit and permanent overhead structures for job cranes are not an option. Hydraulic Gantries are placed on skid tracks to provide a means for moving and placing heavy loads.

“The SL-400 is also a very cost-effective solution for installation and maintenance across a huge range of industries. It doesn’t need expensive foundations or permanent structural support columns for the installation of heavy equipment such as industrial presses, turbines and generators. Workshops and turbine hall floors for loading already have strong foundations for such heavy equipment and the SL-400 can capitalise on that without the need to separately construct stronger foundation works” says Mr Lee.

The SL-400 complements Enerpac’s globally proven range of hydraulic gantries, including the SBL-Series super boom lift, with capacities up to 1100 tons and the MBL-Series mega boom lift, with lifting heights over 12,000mm.

“The SBL-Series is excellent for heavy duty lifting and the MBL-Series is excellent for tall lifts, but where the SL-Series is highly beneficial is within its lifting range of 188-408 tons and height of 9.14m feet, where it is lighter and easier to handle while transporting. It shares an easy assembly/disassembly withal the gantry cranes in the Enerpac range,” says Mr Lee.

“Providing a more advanced solution than standard lifting systems, the SL-400 hydraulic gantry offers unique features such as a wireless control system and integrated self-propelled drive system,” said Mr Lee. “These features, combined with safe, reliable performance, allow our customers to satisfy their complicated lifting applications.”

Featuring a unique Intellilift wireless control system, the SL-400 provides optimum performance and allows for unobstructed views of the load. The control system allows users to operate the lift locally at each leg or use the Intellilift remote control. The wireless system ensures automatic synchronization of lifting with accuracy of 1 inch and automatic synchronization of travel with accuracy of 0.60 inch.

For enhanced durability, the SL-400 offers a sturdy, proven base frame that can withstand a variety of environmental conditions. It can also be equipped with a powered side shift for easy operation, providing the operator with lateral control positioning of loads.

Intelli-Lift

Intelli-lift has been proven as one of the safest possible methods to operate a gantry. It is not just a monitoring system – it is a highly refined control system that has been proven worldwide.

 

 

Features of gantry lifts that are normally extras – such as the control systems and the self-propelled drive motors – are included in the standard configuration of all Enerpac gantries.

The Intelli-Lift controller o­ffers superior safety and control and includes the following features:

• Encrypted bi-directional communication that eliminates interference from other devices
• Remote operation using multi-channel wireless (2.4 GHz) or wired (RS-485) control
• High and low speed settings
• Automatic synchronization of lifting with an accuracy of 24 mm (0.95 inch)
• Automatic synchronization of travelling with an accuracy of 15 mm (0.60 inch)
• Overload and stroke alarms
• Remote side shift control
• Emergency stop switch.

A complete Enerpac gantry system includes 4 gantry towers and legs, 2 header beam units and skid tracks, 4 side shift system units and 2 Intelli-lift remote controller units. Additional units and sets can be supplied for more complex lifting tasks.
