We quickly realized that once a customer has a chance to ride and operator the Linde forklift, we rarely have to “sell” the product anymore…it sells itself. The level of quality and craftsmanship that goes into the design, testing, production, service, and support of the Linde forklift is matched by no other forklift brand in the world.
One of the most prominent features of the Linde product is the Hydrostatic drive system. Leading-edge forklift truck engineering is inseparably linked to the Linde hydrostatic drive concept. Not surprisingly, it is acknowledged as the ultimate drive system – superior to all others – in achieving maximum lift truck performance. Linde has refined the hydrostatic drive to match the working conditions encountered by modern-day forklift trucks, perfecting it to meet every requirement for handling ease, durability, efficiency, and ergonomic operation.
Direction Selection:
The hydrostatic pump differs from a hydrostatic motor in one key aspect. Due to the swashplate being tiltable, the rate at which oil is delivered by the pump can be controlled continuously and precisely – independently of the speed at which the engine drives the pump.When the truck is stationary, the swashplate is in the neutral position and the pistons do not stroke in and out. As a result, no oil is displaced and no power is transmitted to the drive wheels. Pressing the forward directional control pedal changes the angle of the swashplate and the pump starts delivering the oil flow needed to drive the independent wheel motors.The farther the swashplate is tilted, the faster the truck will accelerate.
Changing travel direction is just as easy and convenient. Pressing the reverse directional control pedal tilts the swashplate in the opposite direction. This reverses the inlet and outlet ports and the oil flow rotates the hydraulic motors, generating reverse travel. The operation is continuous with no adverse effect on the hydrostatic system as it transfers smoothly and safely from maximum speed forward through neutral to maximum speed in reverse.
Oil pressure is directly converted to rotation for forward or reverse travel.
The revolutionary feature of this innovative technology is the fact that the wheel motor pistons are fitted into a rotating cylinder block and slide on a fixed swashplate. Oil pressure is pushing these pistons and with that, rotary motion is generated; All this with almost no mechanical friction. Friction and therefore wear is minimized by an oil film between the piston and the swashplate, preventing metal to metal contact.Speed and travel direction are controlled by the hydrostatic pump, driven by the truck’s engine.
- Oil pressure regulates the torque output
- Oil volume controls the truck’s speed.
- Direction of oil flow controls the direction of travel.
Design Advantage. Durability and Efficiency.
Mechanical breakdowns and high servicing expenses are a thing of the past. Durability and efficiency are here to stay with the Linde hydrostatic drive.- No differential: Oil flow delivered by the pump is evenly divided between the two hydraulic motors, no mechanical differential is needed for power transmission.
- No conventional service brakes: Hydrostatic drive slows down the truck by decreasing the flow of oil. As the directional control pedal is released, the truck progressively and smoothly decelerates to a complete stop.
- No transmission: The variable control of oil flow allows flexible speed and random directional changes, eliminates the need for a mechanical transmissions and the extremely costly repairs that tend to come with them.
- No clutch: At all times, the hydraulic pump is controlled via the travel pedals, from neutral to full speed; Eliminating the need for a clutch to separate the drive from the engine.
No Inching Pedal. Increasing Fuel Efficiency.
Hands and feet are very busy when operating a forklift truck. A lot of movements have to be accomplished simultaneously. Training and experience can reduce the physical effort, but the biggest relief is the Linde hydrostatic drive. Without the need for an inching pedal, the Linde can smoothly and quickly transmit power to the forklift functions without needing to rev the engine to higher RPM’s, which in turn increases fuel efficiency.Simplicity.
Travelling forward and in reverse is controlled by two separate directional control pedals (Single drive pedal configuration with fingertip direction control available as an option). The operator of a Linde forklift is able to keep both feet on the pedals. The brake pedal is only applied in an emergency situation, the Linde hydrostatic drive automatically slows down the truck as the directional control pedal is released. Handling of the truck itself is responsive and precise. The operator is almost in complete control with minimal physical input required.
Without Linde hydrostatic drive the operator must go through many unnecessary motions; wasting time and money. The Linde hydrostatic drive system keeps the forklift on track, it accelerates quicker and gets road transport vehicles unloaded much more efficiently. This is achieved without working harder, just smarter. Linde forklifts load/unload more delivery vehicles in less time, using less fuel, and with reduced maintenance requirements.
No Slipping. No Tire Spinning.
With Linde hydrostatic drive the forklift remains securely on track and operates with extreme precision. The absence of a torque converter and mechanical transmission results in the maximum efficiency. This adds up to greater reliability in load handling with distinctly better productivity. In addition, the hydrostatic drive system and absence of mechanical transmission and clutch means Linde forklifts do not spin tires when promptly changing directions. The elimination of tire spin means you greatly reduce the wear on forklift tires and extend component life substantially.Reduce Mechanical Wear. Increase Mechanical Life.
Realize greater fuel economy. This is due to the engine running at optimum rpm at all times. Unlike conventional forklifts, the Linde hydrostatic drive allows for quick changes in direction, hydraulic functions, and operational changes without the need to spike engine rpm’s or mashing the inching pedal to increase operation speed. The hydrostatic system takes the full work load for all basic functions and when you need the extra bit of power to complete the job, the engine kicks in to complete anything you ask of it.Hydraulic oil change intervals only every 6,000 operating hours as a result of the almost wear-free working characteristics of the Linde hydrostatic drive. The oil lasts up to six times longer than the hydrodynamic (torque converter) drive system.
Long service life and low maintenance costs due to the elimination of conventional mechanical consumable costs.
Time savings because it takes less time to do the same job with a Linde hydrostatic-drive forklift. Less strain on both the operator and the machine.
When you consider this entire article has been posted about just a single superior component that helps make up the Linde fokrlift as a whole, just take a minute to consider how advance the machine as a whole is. Countless hours can be spent reading and learning about all of the separate features and benefits of the Linde forklift truck but the best way to understand is to operate one yourself.
