DESIGNING A LOADING-DOCK

Product catalog summary
Commonly Used Equipment
This section provides guidance on selecting dock levellers, dock shelters, industrial doors, and pit types. It includes criteria for choosing products based on specific requirements and offers a summary of widely used applications, such as pit type 320.000 IA, which requires minimal construction work.
Dock Leveller Specifications
The Poweramp 232-710 is an electro-hydraulic dock leveller with a hinged lip, offering a width of 2100 mm and a length of 2770 mm. It provides an effective working range from +350 mm to -320 mm, with a maximum gradient of 12.5% as per EN 1398 standards. The recommended platform length is 2560 mm for versatility and future development.
Dock Shelter Specifications
The Powershelter 403-014 is a collapsible curtain model with dimensions of 3400 mm width and height. It is suitable for vehicles with widths of 2300 mm to 2800 mm and heights of 3600 mm to 4200 mm. The curtain material is available in 1600gr/m² and 3500gr/m², with the former being more flexible.
Industrial Door Specifications
The Powerdoor type 601-010 is an insulated steel sectional door with dimensions of 3200 mm by 3200 mm. It features insulated steel sandwich panels providing a 'U' value of 0.46 W/m²°C and sound insulation of 24 dB. The door is electrically operated and includes various safety features.
Wheel Guides Specifications
Type 970-014 wheel guides are straight and designed to be cast in, with a length of 1850 mm and a height of 320 mm. They are hot-dip galvanized for durability.
Design Considerations for Loading Docks
  • Loading Area: A flat loading area is ideal, with specific slopes for water drainage and vehicle positioning.
  • Height of Loading Dock: The platform height should match the average vehicle loading platform height, with specific heights for different vehicle types.
  • Tail Lift Opening: Minimum dimensions are specified for accommodating hydraulic tail lifts.
  • Dock Leveller Dimensions: Length and width are determined by vehicle dimensions, type of goods, and internal transport methods. Recommended gradients are provided for different transport types.
Specifications:
The document outlines the specifications for dock levellers, including dimensions and types. The standard width is 2250 mm, with various lengths available. Poweramp models are listed with specific dimensions.

Load & Capacity:
To determine the necessary dynamic capacity, the train weight of internal vehicles must be known. The train weight includes the vehicle, driver, and heaviest load. The dock leveller's carrying capacity is equivalent to the maximum admissible train weight, considering the bump-factor. Standard conditions include a capacity of 40 kN, a maximum gradient of 12.5%, and a driving speed of 7 km/h.

Safety Aspects:
Safety is a priority, with hydraulic operation recommended. The hydraulic system should operate at low pressure, with components tested to higher pressures. Safety features include oversized main cylinders, hydraulic lips, toe guards, and conspicuous coloring. Dock levellers must conform to EN1398 standards and be CE/TÜV certified.

Dock Shelter:
The dock shelter seals openings between vehicles and buildings, protecting against weather and maintaining energy efficiency. The standard size is 3400 mm x 3400 mm, with collapsible curtain shelters and inflatable dock shelters available for different needs.

Vehicle Restraint System:
The POWERLOCK® system provides active safety by locking vehicles to the loading platform, preventing accidents from vehicle movement during loading.

Industrial Doors:
Dimensions depend on door type and vehicle specifications. Guidelines are provided for determining door height and width, considering vehicle size and platform height.

Wheel Guides:
Wheel guides ensure exact vehicle positioning, enhancing safety and reducing building damage. They are available in foot plate or cast models and are positioned to center vehicles in front of openings.

Dock shelter type Powershelter 403-014 Curtain model, collapsible projection. Dimensions: Width: 3400 mmHeight: 3400 mm Side curtain: 600 mm Head curtain: 1000 mmWhile other dimensions are also possible, these dimensions are the most commonly used. The most commondock heights (1100 mm-1300 mm) the top of the dock shelter will be 4500 mm to 4700 mm above ground level. This is a practical height as the general vehicle heights are 4200 mm. Should higher vehicles need to be catered for then it is possible to increase the dock shelter height. The result will be a free space of 2200 mm between the...

DESIGNING A LOADING-DOCK-10

Before you choose the type and dimensions of the dock leveller, we would advise you to make an inventory ofexternal transport vehicles, goods to be loaded and unloaded and internal transport vehicles. This information is essential for selecting the dock leveller most suitable for your application. Length of the dock leveller. The length of the dock leveller is determined by the maximum acceptable gradient which is governed by theinternal transport and type of load. With a greater difference in levels between the vehicle bed and the building floor the dock leveller must be increased in length...

Load & capacity of the dock leveller To determine the necessary dynamic capacity, the train weightђ of the internal vehicles that are used on thedock levellers must be known. Train weight = Rated load = weight of the internal transport vehicle with driver and heaviest load.For example: Train weight: Fork lift truck 3000 kgLoad 1000 kg Total 4000 kgIn Conformity with EN 1398, Loading Systems calculates that 100% of the train weight rests on the front axleof the internal vehicle. Through that, the definition of the carrying-capacity on the dock leveller is the same as the maximum admissable train...

Safety aspects. Statistics show that the loading bay area is one of the most dangerous working places in a plant. In theory,safety rules and disciplinary codes are observed but in practice these are widely ignored. This occurs most commonly when pressure to finish a job quickly results in driving at excessive and potentially dangerous speeds. Loading Systems, therefore, makes safety provisions one of its highest priorities.Safety means eventually the well being of people and goods. A few important SAFETY CONSIDERATIONS a dock leveller must meet: The operating system Ideally a dock leveller should...
