Increased
productivity
Light but strong, Portalift rail hoists have been
designed to allow easy maneuverability and positioning
by one operator. Hoist mounted control cabinets
and remote pendant allow easy operation and complete
control. |

|
Precise
and reliable operation
Portalift's recirculating ball system is virtually friction-free,
with a mechanical efficiency around 95%. This offers an
extremely efficient and smooth operation. |

Maximum
safety
A range of safety features are incorporated and active at
every stage of operation. Remote pendants allow the operator
to safely operate and observe the lifting operation from any
point around the vehicle, clear of the lifting zone.

General
Specifications
Construction
The all-steel hoist assemblies have a twin column mast
mounted on a forked base. The lifting assembly is mounted
on the mast and equipped with two front and two rear load-bearing
guide rollers. All rollers have sealed ball bearings that
carry the load and side thrust.
|
|
|
|
|
|
Positive
Stop Safety Device
Each hoist is fitted with a unique centrifugal braking
system at the base of the shaft.
|
|
|
| |
|
|
|
Drive
Mechanism
The electric brake motor drives the lifting mechanism through
a worm gearbox connected directly to the top of the drive
shaft. The drive shaft is a precision-ground steel screw,
with two recirculating ball nuts. The load is taken on the
drive shaft in tension. The drive shaft hangs from a lubricated
self-aligned bearing at the top of the hoist. The lifting
assembly is always held true on another lubricated self-aligning
bearing. |

Operation
Maneuverability
Portalift
hoists have been designed to allow easy maneuverability
and positioning by one operator. Under load the hoists settle
securely on the floor with four-point contact. All hoists
are fitted with a handling and carry point at the top.
Remote
Control
The lifting and lowering modes are controlled from the remote
pendant. This allows the operator freedom to safely observe
the lifting operation from any point around the vehicle.

|
Precise and reliable
Unlike Acme-type screws, Portalift's
recirculating ball system is virtually friction-free, with
a mechanical efficiency around 95%. This offers an extremely
efficient and smooth operation. Because of the "rolling"
contact between nut and shaft, both these surfaces can be
hardened material, reducing wear and increasing life. This
avoids the inherent wear problems of the hardened shaft and
softer bronze nut of the Acme thread screw system.
