Definitions

  • the present invention relates to a nacelle for person lift vehicle and a person lift vehicle.
  • a nacelle linked to the end of a steerable lift arm adapted to move said nacelle in a three-dimensional space
  • said nacelle having a floor adapted to support at least one person and a railing rising around said floor so as to delimit a safe cabin for said at least one person in a standing position.
  • the nacelle is designed to accommodate one or two operators in a standing position to perform different types of work in elevation above the ground.
  • the guardrail is high enough to prevent the main risks of falling operators, without exempting them from safety measures appropriate, such as wearing a safety harness connected to Platform.
  • Type 1 lifting vehicles do not can not move while the basket is high. On the contrary, stabilizing feet are usually provided to immobilize the vehicle stably before any movement of the nacelle, which may rise for example up to 15 to 17 m high.
  • Such vehicles type 1 are in particular used on roads for the replacement of road lighting lamps and for the laying of electrical networks on pylons.
  • Type 2 lifting vehicles are authorized to move with the platform in height. They meet mainly in the railway field, where they are used for maintenance.
  • type 3 elevating vehicles the lift arm is mounted on a self-supporting module that can move while the basket is high. However, the self-supporting module can only move on land well stabilized and at low speed, for example at 3 km / h.
  • These Type 3 lifts are mainly used indoors sheds and factories.
  • US-A-3,605,941 and US-A-3,695,390 describe vehicles lifts with a carrycot conforming to the preamble of These vehicles are designed to be used by a only one operator who alternately operates the vehicle and work in the basket. The gondola is therefore clearly not designed to be occupied while traveling the vehicle. Indeed, weather protection covers that equip these nacelles are made of sheets of flexible foldable materials and must be removed when moving the vehicle.
  • the present invention aims to provide a vehicle lifting person overcoming these disadvantages.
  • the invention provides a vehicle nacelle elevator, said platform having a floor adapted to support at least one person, a railing rising around said floor so as to delimit a safe passenger compartment for the said at least one a person standing, and a seat.
  • the basic idea of the invention is to equip the nacelle with in order to secure the operator during the movements of the vehicle, the nacelle being in the low position.
  • the nacelle must constitute a post which the operator can stay, including during vehicle movement on the road. It turned out that a seat was the essential equipment to achieve this goal.
  • the seat can be of any type.
  • the seat is retractable, such as a jump seat. This characteristic saves space in the basket, since the seat is not intended to be used once the platform is in the up position.
  • the seat is provided with a seat belt. This feature helps to further secure the operator sitting on the seat in the basket.
  • a harness worn by the operator could be used to attach the operator to the seat.

  • the nacelle according to the invention comprises a held-action device arranged to be operable by a person sitting on the seat.
  • a device with maintained action for example a dead man's handle or, to a lesser extent, a pedal, has a high level of safety because it requires action continuous operation, an action that can not be easily simulated.
  • a such a sustained action device can also be arranged in such a way that its actuation is practically only possible by one person sitting on the seat, so that at the same time it ensures the function of detect the presence of the person in the correct security position.
  • the invention also provides a lift vehicle of person, characterized by the fact that it comprises the aforementioned nacelle linked to the end of a steerable lift arm adapted to move said nacelle in a three-dimensional space.
  • a lift vehicle of person characterized by the fact that it comprises the aforementioned nacelle linked to the end of a steerable lift arm adapted to move said nacelle in a three-dimensional space.
  • said nacelle comprises a console of command to control the lift arm and a device for stabilizing said vehicle.
  • the control of the stabilization device since the nacelle has the advantage of allowing the operator to take charge of the stabilization of the vehicle as soon as it stops while staying in the basket.
  • the nacelle comprises an action device maintained being operable from a passive state to an active state, said device with maintained action being connected to a device for signaling arranged in a cab of said vehicle to signal to a driver of the vehicle that said maintained-action device is in the passive state.

  • the vehicle according to the invention comprises a signaling device arranged in a cab of the vehicle and connected to a vehicle speed sensor to signal a driver of the vehicle exceeding a predetermined speed threshold.
  • a speed reference ensuring the safety of the operator in the platform, for example example of the order of 30 km / h, can be recalled automatically to the driver, at least when the operator is present.
  • the vehicle has a sound device adapted to be controlled from said nacelle to warn a driver of the vehicle.
  • a sound device for example in the form of a horn or an intercom, allows the operator in the nacelle to communicate with the driver, for example to signal that the vehicle has reached the point of intervention or that the operator is ready for a move of the vehicle.
  • the vehicle according to the invention comprises a audible device adapted to be controlled from a cabin of said vehicle to warn said at least one person in the basket.
  • a audible device adapted to be controlled from a cabin of said vehicle to warn said at least one person in the basket.
  • Such device allows the driver of the vehicle to warn the operator in the platform for starting and stopping the vehicle.

  • the dead man handle 14 is an action device maintained which is by default in a passive state and is switched in an active state by pressing an actuating button 15.
  • the handle 14 may also be placed lower than in FIG. example at a level such that the button 15 is substantially at the height of the seat 11 in its deployed position. In this low position, the handle 14 can practically be operated only if the operator sits on the seat 10, which reinforces the reliability of the indication given by the actuation of the button 15.
  • the handle 14 can also be replaced by a pedal.
  • Vehicle 1 has a non-audible warning device represented, for example a conventional horn, which can be ordered from the cabin 2 of the vehicle to be able to send warning signals to the operator in the basket.

  • the operator accesses the platform 5 by opening the gate 8 and closing it behind him.
  • a limit switch 28 is provided to detect the closing position of the gate 8.
  • the detector 8 is connected to the control panel wiring 16.
  • the operator takes place in the nacelle 5 when it is in the low position. He must preferably wear safety equipment, such as a helmet and harness with a lanyard 1 to 2 meters long that it stows to the basket 5.
  • the operator who took place in the basket sits on the seat 10 and attaches by means of the seat belt 13.
  • the seat deployment detector 29 offers a lower level of reliability than the dead man handle 14, since the seat 10 can still be maintained deployed in placing a heavy object on it.
  • the dead man handle 14 really requires a sustained action from the operator who can not be easily simulated by an object.
  • the operator is in a position of safety against road risks. It is furthermore protected against possible obstacles on the way of the vehicle 1.
