Dock levelers and dock lift :

dock levelers

 

Dock levelers have introduced a new level of safety and security to loading docks in thousands of warehouses and distribution center. We offer a wide range of loading dock equipment to meet your specific needs. From levelers to accessories, Dor  Dok systems has the experience to get the job done right. If you are looking for quality loading dock equipment at competitive prices you’ve come to the right place. “The hydraulic option gives you more versatility than either mechanical or air dock levelers and typically would have lower service and maintenance costs.” Hydraulic are preferred over mechanical and air activated dock levelers.

There are mainly five type dock leveler

  • Mechanical dock leveler
  • Hydraulic dock leveler
  • Hydraulic / Mechanical Hybrid
  • Pneumatic[ Air powered] low pressure high volume
  • Vertical dock leveler
  • Edge of dock leveler

When conditions make a pit style leveler not possible, there are other solutions

  • Free standing frames
  • Mast Lifts
  • Scissors/ Dock Lifts

We also offer fully Automatic levelers no dock attendant is required.

Factors while selecting dock leveler

Width of Dock Leveler:

There are three common widths 6’ wide, 6.5′ wide and 7′ wide, nominal and special 9’, 6’, 8’, 10’, & 12’ standard lengths. The special hydraulic dock leveler that is a full 9′ wide, will lower 12” below dock to provide fast, efficient access to low trailers. In addition, the 7’ wide main deck will service trailers 12” above dock. This special leveler will also function as a standard dock leveler, specially designed to service the loading and unloading of trailers below dock height.

Length of dock leveler:

Dock levelers are typically available in 6, 8 and 10 ft (nominal) lengths. Longer lengths are utilized when the difference in height between the loading dock floor and the truck to be serviced increases. The most common length for dock levelers is 8 ft long (nominal). This length suits most applications. 6 ft long (nominal) levelers are suitable when there are minimal height differences between the dock and the truck / trailers.

Lip length:

There are three standard lengths of hydraulic dock leveler lips, 16”, 18″, and 20″. The length of dock leveler lip required depends on various factors including but not limited to: the projection of the dock bumpers, types of trailers being serviced. Generally the lip should extend 12” past the dock bumpers.

Driveway approach:

We offer dock levelers to suit every application from a 25,000 lb capacity levelers to 160,000 lb capacity hydraulic dock leveler. Mechanical dock levelers from 25,000, 30,000,35,000,40,000, 45,000, 50,000. Pneumatic levelers from 25,000 to 60,000 lb capacity.

Mechanical dock leveler

Mechanical Dock Levelers are a simple, lower price point alternative to Air or Hydraulic powered dock levelers. Mechanical levelers are a good option when power isn’t available at the loading dock or low dock traffic volumes do not warrant the investment in more expensive powered dock levelers. Advancements in leveler design have created mechanical levelers that are easier to operate and more reliable than ever. Hold-downs are released manually to allow the deck of the dock leveler to rise for use or to be restored to the parked position, when the truck is still at the dock. This is done by pulling a hold- down release ring installed in the dock leveler deck. The pull force required to release the hold-down is always a concern. The release forces for the ratchet and pawl hold-down can beup to 100 lb. when it is compensating for upward deck oat; even under best case conditions 20 – 30 lb. of pull force is required. The “Easy Float” hold-down only requires pull force of approximately 8 lb. throughout the entire operating range of the dock leveler.

Easy Float hold-down Vs Ratchet Pawl hold down

Controlled automatic compensation of the brake assembly, under a light upwards force (approximately 200 lb.), allows dock leveler deck to oat gently upwards and maintain positive lip contact with the truck bed the break band design assures that automatic compensation force will remain constant throughout the entire operating range of the dock leveler. The high strength nylon strap absorbs shock loads due to its semi elastic properties. Compared better than Ratchet and pawl hold down why ? The shock load stresses during float bear directly on the hardened metal ratchet bar and the rigid pawl teeth. These damaging conditions, common during normal usage, cause aggravating ratchet and pawl teeth failure . The teeth automatically release and reset under spring pressure, causing premature ratchet and pawl failure.. The best on the market and the better on design and field tested and time proven is Easy float mechanism. from pentalift.

Vertical Dock levelers

Vertical levelersCommonly known as Cold Storage levelers directly contribute to environmental efficiency, security and cleanliness. An energy efficient alternative to vertical storing levelers. Install the Nordock telescopic lip leveler [TLH] for your loading dock.

The Vertical Storing Telescoping Lip Leveler (NVTL) is the first-ever vertical storing leveler without a rotating lip. If you need climate control and want your loading dock to help increase your business efficiencies, this is a big deal. Rotating lips are the root of many dock problems.

Why it is a better solution ?

  • Completely eliminates time-consuming issues with end loads
  • Options include integrated combo controls (Logi-Smart), vehicle restraints, seals & shelters
  • Precise lip control eliminates product damage
  • No vehicle restraint damage or clearance issues
  • No interference from a rotating lip allows for the only Bumper to Bumper barrier – the first true pit seal
  • No vehicle restraint damage or clearance issues
  • Longer equipment life with no rotating lip hinge components
  • Increased climate control

Vertical NV leveler offer significant Advantage

  • Engineered for superior climate control, security and energy efficiency
  • Inside vertical storage allows for overhead dock doors to fully close to pit floor
  • Protects dock door from damage and impact from fork trucks
  • Power-up and power-down deck operation for a safer vertical storing leveler
  • Emergency stop and full lip controls
  • Self-cleaning lip hinge avoids nuisance service calls
  • Superior design allows NV levelers to fit into all sized existing pits, re-using embedded
    Chanel thus
    Options include longer lips, foam-filled front pit seal, integrated Logi smart control panels to operate truck restraints (dock locks), doors, lights and more

Installation style

Continuous pit / ledge construction

Continuous pit/ledge construction improves dock area cleaning and maintenance and simplify es building design and construction.

Individaul pit construction

Individual pit construction allows the space between levelers to be used for storage while still allowing the overhead door to close and seal at the pit floor.

Roll Off Stop Dock Levelers

We proudly offer Roll off stop dock leveler from pentalift

Safety at the loading dock increases dramatically when you include the Pentalift Roll Off Stop Lip series of dock leveler. This extra safety measure at your loading dock will offer peace of mind when your overhead doors are open and fork lifts operating within the danger zone. The Roll Off Stop Lip dock levelers offer a guard which is designed to stop the forklift if it happens to drift too close to the edge of the leveler while performing its duties. Pentalift offers two series of roll off stop dock levelers.The HDRS series roll-off stop lip dock leveler is designed and built to provide all the benefits of the series HD / HDRS dock leveler with the additional benefit of providing a formidable barrier. The barrier created by the roll-off stop lip prevents lift truck roll-off from the loading dock, whenever the dock leveler is in the parked position. Convenient push-button activation and proven hydraulic technology increases the efficiency and safety of the loading/unloading process. The HDRS series roll-off stop lip feature provides maximized safety for vacant door situations when no truck/trailer is in position.
