Designed for heavy lifting

20 February 2017


Enerpac will exhibit the new SPMT600-360 self-propelled modular transporter and the new JS-250 jack-up system at ConExpo 2017, in addition to showing other heavy-lifting products, such as the SBL500 hydraulic gantry, the HSL7006 strand jack, the EVOB816J synchronous lifting system and the SFP404SJ split-flow pump. A wide range of tools for the construction market will be also at the expo, at stand G1127.

The new SPMT600 provides a compact solution for transporting heavy loads. Designed for in-plant operation, the Enerpac SPMT’s slim height and compact frame make it easy to lift, manoeuvre and transport a load in a confined space. Each wheel has an individual drive motor, steering actuator and lifting cylinder.

A single trailer can transport up to 67USt. Equalised suspension automatically spreads the weight of a load across each of the connected trailers and wheels.”

The SPMT600-360 features a slew-drive steering system that is capable of ±179° steering and maximum configuration of six trailers in two rows.

Hydraulic power units include one power pack that can operate a maximum of three trailers and use Tier-4 diesel engines for reduced emissions. For easy transportation, two trailers and a power back can be shipped inside a 20ft container.

The SBL500 hydraulic telescopic gantry has a lifting capacity of 585USt with four towers in the first stage. The heavy duty SBL-Series Super Boom Lift gantries can raise loads heavier than 400USt to heights of almost 12m.

The HSL7006 strand jack has a capacity of 79t with a strand diameter of 0.62in (15.7mm). 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 simultaneously, which is how the strand jack is able to carry a load.

Lifting and lowering a load is achieved by hydraulically controlling the main jack and both anchor jacks alternately. Enerpac uses Smart Cylinder Control (SCC), ensuring full control of lifting and lowering. The JS250 jack-up system has a lifting capacity of 280USt, using a modular tower with a maximum side-load of 3% at 10m.

Self-contained hydraulics in each jack-up unit enable an uncluttered workspace, as well as the ability to synchronously lift loads with multiple jack-up units.

The most common system set-up includes four such units. Lifting barrels are stacked together to mechanically hold the load.

The EVOB816J synchronous lifting system can control and synchronise the movements of eight lifting points.

Sensors monitor and optimise the lifting, lowering and positioning of any large, heavy or complex load, regardless of weight distribution.

The Enerpac EVO-Series can provide the required level of force and control for most applications. The main features include a single operator to control all movements from a central position and single or double-acting cylinders with the same or different lifting capacities.

EVO offers additional features, including a greater number of lift points, centres of gravity, and tilting/ weighing capabilities. The Basic EVOB can also provide an economical solution to basic applications requiring stroke-only control for a maximum of eight lifting points.

The SFP404SJ split-flow pump features up to six outlets; individual or simultaneously operation of valves, with advance/hold/retract function; joystick (manual) controlled or pendant (solenoid) controlled valves; flow per outlet ranging from 33–305in3/ min (0.27–4.20L/min) at 10,000psi (700bar); for double-and single-acting cylinders; and an adjustable pressure relief valve a circuit.

Enerpac’s SMPT600 is ideal for use in confined spaces.
