A new era for tracked aerial platforms

As AlmaCrawler continue their research and development into new technologies, the hire and rental industry now benefits from an innovative, patented machine functionality, Bi-Levelling.

Italy-based AlmaCrawler has evolved the capabilities of access equipment beyond traditional aerial platform designs to revolutionise access in normally difficult places. The patented technology, bi-levelling, is installed on all lifts produced by AlmaCrawler.

Coupled with anti-collision detection technology, AlmaCrawler machines are considered one of the safest and most reliable in the world.

What is bi-levelling?

Bi-levelling is a sophisticated system of automated hydraulics allowing access equipment to overcome longitudinal slopes of up to 20 degrees and lateral slopes of up to 15 degrees, depending on model.

Auto-levelling of the chassis or aerial structure, even in extreme conditions significantly increases performance, safety, and operator comfort.

This innovative technology will overcome many worksite challenges where inclined terrain or multi-level surfaces would otherwise require additional equipment and operators, accompanying safety measures, time and expenses.

This unique product capability, with simple user experience, ensures a far greater overall return on investment.

The technical overview

ATHENA Scissor Lifts Three independent hydraulic cylinders mounted in the undercarriage of the scissor lifts achieve automatic levelling for lateral and longitudinal inclination.

Using two independent bi-level legs enables unique worksite positioning including, in certain circumstances, operation on multi-level surfaces such as a raised concrete slab or steps.

Twin channel inclinometers measure real time chassis inclination and platform height. If the system detects change, an alarm sounds. The system will not permit lifting until the chassis is within the safety of a zero-degree level.

JIBBI Boom Lifts Automatic levelling of the JIBBI is completed using a unique dynamic, aerial structure design adjusted at the slew ring base by means of two hydraulic cylinders.

Prior to lifting, the automatic levelling program completes adjustment of the aerial structure alone, bringing the inclination to zero-degrees. Isolating this

Bi-levelling is installed on all Almac lifts.

adjustment allows the JIBBI to maintain a fixed and stable undercarriage footprint, while operating on inclines up to 15 degrees in any direction.

The JIBBI leveling system uses twin channel inclinometers on all individual moving components. An onboard electronic control unit compiles data in real time during operation monitoring for inclination changes of the chassis and base sensors greater than one degree.

Billennium Spider Lifts

The Billennium is the first spider lift of its type, able to work at height with or without the stabilisers deployed. It uses four hydraulic stablisers to achieve automatic levelling.

When operating on longitudinal slopes up to 10 degrees, or lateral slopes of up to five degrees, an operator may choose to work without the stabilisers deployed. This ensures a narrower footprint and allows elevated driving.

When working on greater slopes, the stabilisers can be deployed automatically from the operator’s control station, without leaving the platform.

The onboard computer system monitors ground pressure of the stabilisers using pressure transducers installed in each stabiliser cylinder. With correct ground pressure set, the cylinders are modulated to obtain zerodegrees of the chassis prior to lifting. A single automatic levelling switch controls the chassis level.
