Grove GMK-5220 Crane Cab Access Platform - Raise Function

The Australian Diversified Engineering (ADE)crane cab access platform is a four stage electric-over-hydraulic folding system. It utilises a 24V DC hydraulic power pack coupled with a manifold of hydraulic sequence valves and pilot operated check valves to drive and control the hydraulic cylinders that raise and lower the access platform. The platform is stowed in the vertical position for transport. When needed, each platform unfolds to the horizontal position at the press of a button. An excellent solution for working at height issues.
Control. Push button controls located on both sides at front of carrier and in the crane cab. "Dead Man" switch function for optimum operator control and safety. It provides safe access and egress for operation and maintenance(for the crane driver and riggers as well as maintenance crews).
Electrical and hydraulic safety interlocks to prevent inadvertent operation. Designed in accordance with Australian Standards AS 1657 and AS 3868.

and it will take me or someone 55sec to forget about that thing and it will get trashed.

@XKP69X Been in service for over three years....no problem. Customer meets their OH & S obligations with it. They don't without it.

A standards compliant permanent ladder is not possible as it compromises the crane functions.

[rrrohan2288]

talk about over complicating it

[orx626]

Each stage exists for a specific reason...as per the crane owner's requirements.

I'm curious. Whilst a lovely piece of engineering, what were the circumstances under which the existing ladder was unsuitable for the client?

This solution (IMO) presents more hazards than it solves, obstructing the doorway in the event that the operator needs to egress rapidly, or if rescuers are trying to reach the operator after an accident. Especially pertinent since the walkway seems to obstruct access to the exterior door handle (positioned specifically NOT to be a work-at-height issue).

not very usefull, if the stairs are fixed you can up and down if the crane tower is operating (90. 180º..) if are fixed, you can up and down every moment and reduce the accidents of falls with

@SoooSIRIUS its all to do with health and safety.

[SoooSIRIUS]

Completely unnecessary and rather dumb if you ask me.. you still have to climb up the 10 steps as oppose to the 4 attached to the carrier right below the cab.. and what are your supposed to do if you NEED to get out of the cab for whatever reason? wait 55 seconds for your electric ladder to unfold? or barrel roll over the rail? Im amazed at some of the stuff engineers are paid to design.

Wait, that V shaped thing underneeth the cabin. Isn''t that a ladder ? XD

[Listendudeok]

Wow pure luxury

[rrrohan2288]

lol he requested a 55 second delay before he can actualy do anything as apose to having a perment ladder in position?

its cool though
