Problems solved by technology

[0006] More recently, hybrid electric-hydraulic telehandlers have been developed in order to reduce energy consumption and improve environmental sustainability. However, this hybrid electric-hydraulic telehandler only partially handles operations that affect conventional telehandlers and other operations. Vehicle efficiency, noise and pollution limits

Embodiment Construction

[0014] Referring to the drawings, numeral 1 generally denotes an electric stabilizer according to the present invention.

[0015] In more detail, the invention is designed especially but not exclusively for application to electric telehandlers 10, that is to say, "all electric" or hybrid; this does not mean that the proposed stabilizer cannot also be installed in On telehandlers with a "classic" drive (that is to say, a diesel or in any case an internal combustion engine).

[0016] Furthermore, the telehandler 10 on which the invention is to be mounted can be both stationary and rotating, and in the second case it is equipped with a rotating tower 100 .

[0017] The telehandler 10 comprises a carriage 2 movable on four drive wheels 3 and a lifting arm 4 articulated to the carriage 2 or to a swivel tower 100, which can be operated using suitable hydraulic actuators, in particular hydraulic Cylinder) to lift and extend telescopically.

[0018] Furthermore, at its distal end, t...

Abstract

Described is a stabilizer (1) for a telescopic boom forklift truck, comprising a support frame (11) designed to be mounted on a carriage (2) of the telescopic boom forklift truck (1) and two telescopic booms (12, 13) fixed to the frame (11), each telescopic boom comprising a first hollow section (121, 131) directly connected to the frame (11) and a second hollow section (122, 132) slidably inserted into the first section (121, 131). An electromotive pull-out linear actuator (18) is positioned inside each arm (12, 13) and has one end secured to the first segment (121, 131) and one end secured to the second segment (122, 132).

Description

technical field [0001] The present invention relates to a stabilizer for a telehandler that is at least partially actuated by electricity. [0002] In more detail, the invention is designed both for electric telehandlers, that is, with a hybrid power supply and "all-electric", that is, fully electric, and for internal combustion telehandlers, in particular diesel car. Background technique [0003] A prior art telehandler ("telehandler") comprises a vehicle equipped with a movable frame on wheels, a cab and a telescopically extending operating arm. [0004] At the distal end of the arm there is equipment for lifting and / or moving the load, such as forks, cages, lateral transfer units, cranes, etc. [0005] Telehandlers are traditionally equipped with a diesel type internal combustion engine which drives a hydrostatic pump which controls a pump which drives a hydraulic distributor which in turn drives the cylinders which generate the movement of the arms and stabilizers . ...
