Rigging with Alternative Equipment 2


Introduction

• Christopher E. Cox, PE • President, Engineered Rigging

• Board Member, Precision Surveillance Corporation

• Bachelor of Science – Civil Engineering

• Bogdan I. Gaita, Eur-Ing.• Vice President, Engineered Rigging

• Bachelor or Science - Civil Engineering

• Master of Engineering - Structural Engineering


What is Rigging with Alternative Equipment

• Alternative conventional crane & hydraulic gantry solutions

• New approach for specialized lift systems and rigging hardware

• Thinking outside the box during concept and engineering

• Rigging solutions with more flexibility built in – modular approach

• Safety at the core of the design

• Systems with higher lift capacities

• Cost savings through safety, installation & implementation

• Risk management

Self Erecting Tower

(ESET)

• Configurations between 1000 tons

and 2400 tons

• Lifts heights of up to 250 feet

• Self-erecting configuration

• Free standing design: no guy wires

required

• System is shipped in standard

containers

• Set up on skid tracks


Self Erecting Tower

(ESET)

• Configuration with strand jacks for

lifting

• Top side can slide sideways for

positioning of the lifted object

• Complete Tower can slide back

and forth, even when fully erected

• 100 Ton crane needed for base

erection

• 3 meters per hour self erecting

speed

Pipe Modular Lift System

(PMLS)

• Lift Capacities: 400, 800, 1,200

and 1,800 tons

Control System

• Lift speed: 20 inches per minute

• Vertical travel distance up to

200 feet

• Deck openings of 50 feet or larger


Pipe Modular Lift System

(PMLS)

• Square, rectangular or round

layouts

• Deck designed to accept SPMTs or

any other material handling

equipment

• Power and mechanical failsafe

• Assembles in 3-4 shifts

• Operating wind speed of 50 mph

• 5 percent side loading

• Mobilizes via 12 standard ground

transportation trailers

Jack-up System (JS Line)

• Fully controlled and automated

jacking system that makes use of

base lifting frame and steel boxes

called barrels.

• Lift capacities between 125 tons

and 800 tons per lifting unit

• Jacking speed up to 20 feet per

hour

• Starting height as low as 6 feet

• Push-up height exceeding 80 feet


Jack-up System (JS Line)

• Barrels handled by forklifts onto

feeding tables

• System is fully automated. No

need to handle the barrels into

place

• 3 to 5 percent side loading

depending on model

• Ships inside standard sea

containers



Jack-up System (JS Line) animation


Mega Jack System

• Innovative design engineered to

push up structures of staggering

weights and sizes

• 5,200 tons capacity per tower

• System uses multiple towers

operating together

• Control of the system is done by

computers

• 12-tower system gives net jacking

capacity of 60,000 tons


Mega Jack System

• Standard base dimension is

approximately 16 feet 6 inches by

16 feet 6 inches

• Each tower has 4 strong jacking

stools. Within each stool is a 1,300

tons hydraulic jack

• Hydraulic jacks have 49 inches of

stroke

• Beams automatically inserted using

the integral roller system

Travel Gantry (ETG)

• Combining the safety and

efficiency of gantries with the

SPMT technologies

• Expands from container size to a

footprint of 32 feet long by 16 feet

wide

• Safe working load of up to 60 tons

• Lift heights of up to 26 feet or 2

containers

• Travel speed of 1.5 mph


Travel Gantry (ETG)

• 7.5 ton auxiliary winch included in

the system

• Self contained hydraulics

• Telescopic cylinders

• All diesel driven hydraulics built in

design

• Steering modes: normal, crab and

carrousel

• Automatic foldable in less than

one hour



Travel Gantry (ETG) video

Scorpion System

• Frame uses friction to support the

crane on a single wall

• Wall clamping force is

continuously monitored by load

cells with digital readout unit

• No structural alterations or

modifications to the wall

• Eliminates the need for pre-

installed crane base or

counterweights


Scorpion System

• Frame extends vertically less than

4 feet from the top of the wall

• Compact design requires wall

length of less than 10 feet

• Independent downriggers

accommodate variances of wall

thickness

• 360-degree load handling capacity

• Installs in a single shift and

relocates as a single unit

Self Propelled Modular

Transport (SPMT)

• It is a 3 axle modular system

• Maximum configuration: 2 rows of

6 units

• Width of only 7 feet 6 inches

• Capacity of 60 tons per unit

• Height of 30 inches to 45 inches

• All wheels with individual drive

motors

• Steering modes: normal, crab and

carrousel



Transport (SPMT)

• Maximum ground bearing pressure

200 psi

• Equal wheel loading by using

intelligent hydraulic dispersion

• Wireless control system with

analog driving unit and directional

controls with the use of one

joystick

• Ease of connection of separate

trailers into one configuration



Self Propelled Modular Transport (SPMT) video


Transport (SPMT)

• 4 or 5 axle self propelled modular

transporter system

• Configurations of 2 rows, each

with multiple 4 and 5 unit modules

• Width of only 7 feet 6 inches per

unit

• Capacity of 140 tons and 180 tons

per unit

• Height of 25 inches to 33.5 inches



Transport (SPMT)

• Two axles per unit with drive

motors

• Equal wheel loading by using

hydraulic dispersion

• Wireless control system with

multiple joysticks for leveling and

steering operations

• Ease of connecting multiple units


Rigid Chain Technology

• Mechanical linear actuators used in

combination with chain technology

• A simple and robust system

• Designed to move heavy loads

over long strokes

• Can be used as horizontal push

system or vertical lift system

• Highly compact single block

design


Rigid Chain Technology

• Accuracy and repeatability of

positioning

• No spring effect when loads are

moved on and off the top deck

• The load is only exerted on the

ground and not on any other

structures

• Very light servicing and

maintenance


Shark Link Heavy Lift

System

• System consist of a support frame

and interlocking links designed to

work in conjunction with a

standard 2 or 4 leg hydraulic gantry

• The system required no complex

electronics

• Set-up and break-down can be

performed by a small crew with a

45 ton assist crane


Shark Link Heavy Lift

System

• Operation of the system required

only 4 persons and one operator

• Shark links are never handled by

personnel, as they are rocked over

into their storage racks

• Due to the low headroom

requirements of the system, both

the load and gantry could pass

through small openings
