The SHAS-Series Synchronous Hoist System is a below-the-hook sling adjuster (hydraulic turnbuckle) comprised of multiple self-contained, PLC-controlled hydraulic lifting devices. The system enables a single crane to precisely position heavy and unbalanced loads. Each of the lifting devices includes a double-acting hydraulic push pull cylinder with an integrated pump and controls. Integrating the pump eliminates the need for an external power pack and hydraulic hoses.

The wireless remote control ensures a single operator is able to control the SyncHoist while remaining at a safe distance. The operator has full control over load handling; each cylinder can lift or lower independently. The system can perform several types of movements including synchronous lifting and lowering, balancing, and tilting, all of which can be pre-programmed.

1) Standard with 4 lifting points. For more or less lifting points contact Enerpac.
2) WE = with European electrical wiring. Change into suffix “WU” for US-market. Example: SHAS 4 11060 WU.
3) Weight per cylinder.

Enerpac’s family of EVO synchronous lifting systems provides precision control suitable for most lifting/lowering applications.

What is Synchronous Lifting?
To achieve high-precision movement of heavy objects it is necessary to control and synchronize the movements of multiple lifting points.

The PLC-control uses feedback from multiple sensors to control the lifting, lowering and positioning of any large, heavy or complex structure, regardless of weight distribution.

By varying the oil flow to each cylinder, the system maintains very accurate positional control. By eliminating manual intervention, the sync lift helps maintain structural integrity and increases the productivity and safety of the lift.

PLC-controlled synchronous lifting systems reduce the risk of bending, twisting or tilting, due to uneven weight distribution or load-shifts between the lift points.

The jack-up system is a custom developed multipoint lifting system. A typical system setup includes four jack-up units positioned under each corner of a load. A four unit setup has a lifting capacity of 2,000 metric tons (500 tons per unit).

The lifting frame of a jack-up unit contains four hydraulic cylinders in each corner which lift and stack steel boxes. A load is lifted in increments as boxes are slid into the system, lifted, and stacked; forming ‘lifting towers’. A jack-up system is operated and controlled by a computer control unit. Each unit’s lifting and lowering operations occur simultaneously; the computer control unit’s synchronous technology maintains the balance of the load. The hydraulics power units are embedded within each unit’s lifting frame. Safe lifting heights are dependent on the expected side load.

Four models of the jack-up system are currently available:

• JS125
  • Lifting capacity per tower: 125 tons
  • Lifting height: 6 meters
  • Maximum side load: 3% at 6 meters
• JS250
  • Lifting capacity per tower: 250 tons
  • Lifting height: 10 meters
  • Maximum side load: 3% at 10 meters
• JS500
  • Lifting capacity per tower: 500 tons
  • Lifting height: 15 meters
  • Maximum side load: 4% at 15 meters
• JS750
  • Lifting capacity per tower: 750 tons
  • Lifting height: 20 meters
  • Maximum side load: 5% at 20 meters

Rollers facilitate easy entry of boxes into the lifting frame.

The Enerpac Self-Propelled Modular Transporter (SPMT) features a minimized height and slim design, which makes it very easy to operate in confined spaces. Each wheel unit has a steering function as well as a lifting cylinder at its disposal. Wheel propulsion is established by wheel drives.

The SPMT is operated by the Intelli-Drive Remote Controller. This remote controller can be used both hard wired and wireless (based on radio frequency).

The SPMT is a modular system and can be built up to a maximum configuration of six transporters in a row and two in the width. This is the maximum setup of units that can work together on just one Intelli-Drive Remote Controller.

The SPMT is a modular system comprised of trailers with 3 axle lines each and diesel hydraulic power units (HPU). Depending on the model number, the trailers and HPUs can be configured to a maximum of 4 trailers in 2 rows (4×2) or 6 trailers in 2 rows (6×2).

• Modular design for multiple configurations.
• Minimized height and slim design are ideal for in-plant operation

Skidding techniques have been used for centuries. Enerpac has applied high-pressure hydraulics to create the Enerpac HSK Skidding Systems. The HSK skidding system is comprised of a series of skid-shoes powered by hydraulic push-pull cylinders, travelling over a pre-constructed track. A series of special PTFE coated blocks are placed on the skid-tracks to reduce friction. The skid shoes are connected by hoses to a hydraulic diesel driven power pack.

Enerpac Skidding Systems are available in several versions:

• HSKB-Series (Skid Shoe Beam) utilizes a tall skid shoe with built-in push/pull cylinders. Skidding direction can be easily switched by flipping a lever on the attached gripper box.
• HSKJ-Series (Skid Shoe Jack) provide the same functionality as the HSKB with the added benefit of having a built-in cylinder for lifting or leveling the load.
• HSKLH-Series (Low Height Skid Shoe) designed with low height skid shoes that can be linked together. The push/pull cylinder (sold separately) is connected to the first shoe. We also offer a support beam for using the thin track that is not fully supported.

To calculate the minimum required capacity per shoe, the entire load has to be able to rest safely on 2 of the 4 shoes. To skid a load of 500 tons, the required skidding system is HSK2500.

Capacity with 4 towers61 – 1069 ton
Lift Height 3,49 – 14,55 m

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. When used with rail systems, hydraulic gantries also provide a means for moving and placing heavy loads. Hydraulic gantries are a cost effective solution for many lifting and rigging applications.

Enerpac offers three series of hydraulic gantry systems:

• Super Lift (SL) series: cost effective models that offers control and stability
• Super Boom Lift (SBL) series: heavy duty hydraulic boom gantry models that go up to 1000 tonne capacity
• Mega Boom Lift (MBL) series: hydraulic boom gantry models which deliver the stability to utilize a 2 leg configuration and can achieve lifting heights over 12000 mm

Enerpac hydraulic gantries have a number of unique features to ensure optimum stability and safety:

• Self-contained hydraulics and electronics
• Intelli-Lift wireless control system
• Self-propelled wheels or tank rollers
• Foldable boom on SBL900, SBL1100, MBL500 and MBL600
• Full range of supplementary equipment: header beams, lifting lugs, side shift, skid tracks
• All gantries are ASME B30.1 compliant

2) Weight per tower

Capacity 15 – 1250 ton
Stroke 250 – 600 mm

The strand jack lifting technique originates from the concrete post tensioning principle. A strand jack can be considered a linear winch. In a strand jack, a bundle of steel cables or strands are guided through a hydraulic cylinder; above and below the cylinder are anchor systems with wedges that grip the strand bundle. By stroking the cylinder in and out while the grips are engaged in the anchors, a lifting or lowering movement is achieved.

The motion of the cylinders is driven by hydraulic power packs. They can be electric or diesel powered. Our sophisticated SCC software program synchronizes the motion of the strand jacks and adjusts the motion to the loads per lifting point.

• Full control of lifting and lowering through SCC control
• Two sizes strand diameter: 15,7 and 18 mm
