This chapter presents the technical specifications required for the acquisition of Isuzu Electric garbage trucks and loaders. It is presented in two sections, the first section contains the requirements associated with trucks, both compactors and trucks with loading platforms, and a second section contains the requirements associated with loaders.
Section 1. Requirements associated with Isuzu electric garbage trucks
Below are the requirements and technical characteristics of the compactor trucks, the cargo truck and the services associated with their supply.
3.1.1. General Description
The acquisition of a fleet of four (4) one hundred percent (100%) electric trucks powered by Lithium Ferro Phosphate batteries, new, with a single axle and a rear-loading compactor box.
The total length of the truck, including the compactor box, must be a maximum of seven meters (7.0 m).
The trucks will be used for the collection and transportation of solid waste from Ciudad Colonial in the National District of Santo Domingo de Guzmán. The required daily autonomy is 60 km, which must be obtained with a single recharge lasting no more than 3 hours.
Compacting boxes must have a minimum load capacity of 2.1 tons of urban solid waste, with a rear-loading lifting system (lifter) for 1,100-liter plastic containers. The compaction cycle of the compacting box must not exceed 25 seconds.
Considering that between 50% and 65% of the waste will be organic, the truck must contain a leachate tank.
The Bidder shall issue and deliver to MITUR the technical sheets containing the specifications and general characteristics of the trucks and each of their components and equipment that will be used to collect solid waste from the Colonial City described in this specification, in addition to the plans showing the general dimensions (width, length, height), shape, location, views (front, rear, plan and elevations), the compactor box and the lifter, the seats in the cabin, and the battery system that will supply sufficient energy for its operation. The dimensions of the truck must be presented as a single measurement that considers both the truck and the compactor box.
The operating and climatological characteristics are presented below:
a. In a typical work day the vehicle operates approximately 4.5 h and travels 23 km. In each work day the vehicle performs two (2) operating cycles, where each cycle involves the movement of the vehicle from the operating site to the transfer station to eject/dispose of the waste. In each cycle the vehicle compacts approximately 19 times and loads approximately 2.1 tons of waste. In total, in each work day the vehicle loads 4.2 tons, compacts 38 times and ejects 2 times.
a. The distance from the parking site to the operation site is 2 km with an average speed of 30 km/h, and the distance from the operation site to the transfer station where the waste is ejected is 3 km with an average speed of 30 km/
h. In this way, 43% of the total journey (10 km) is made at the operation site with an average speed of 15 km/h.
b. In summary, the following phases are carried out in a work day:
c. Although the operation has a transfer station relatively close to Ciudad Colonial, the desired minimum autonomy considers the case where the electric truck must transport and dispose of waste directly at the Duquesa landfill,
which would add a total of 32 kilometers to the 23 km indicated in the table above. Thus, considering a safety percentage of 10%, the minimum required autonomy of 60 km per charge is determined during the battery warranty
period.
a. Three of the vehicles will have two shifts that can extend up to 6 hours of work each. The collection frequency is six (6) days a week for the 3 vehicles, on the seventh day only two vehicles will work. The fourth vehicle will be in stock for contingency or replacement
of any of the three previous ones when they require preventive or corrective maintenance or presentation of a mechanical or electrical failure.
b. The minimum capacity of the charger is estimated in order to mitigate the unforeseen event of requiring the truck for a third day. If this is the case, the charger must be able to supply 20% to 100% of the charge to the battery of the electric truck for a maximum duration of 3 hours.
c. The climatic conditions in Ciudad Colonial are predominantly tropical, over the course of the year the temperature generally varies from 20 °C to 32 °C and rarely drops below 18 °C or rises above 33 °C.
d. The topography of the routes is on average flat and the roads are 100% paved.
e. The traction system must allow the trucks to reach a speed of 80 km/h and the ability to overcome slopes of at least 20% at maximum load (full load).
The required range for each work day is 60 km, which must be obtained with a single recharge lasting no more than 3 hours. Although the battery is expected to have a minimum capacity to store 100 kWh, proposals are accepted that support that the battery offered will have the required range considering its degradation during the warranty (60 months at 20% maximum degradation and 96 months at 30% degradation) and the safety percentage required by the manufacturer, approximately 20%. Proposals must present an extended liability plan on the proper disposal of the batteries at the end of their useful life.
Compacting boxes must have a minimum load capacity of 2.1 tons of urban solid waste, with a rear-loading lifting system (lifter) for 1,100-liter plastic containers. On average, the collection speed is 1 ton in 22 minutes.
Considering that between 50% and 65% of the waste is organic, the truck must contain a leachate tank.
In accordance with these technical specifications, the interested bidder must submit a detailed sketch of the specifications of its proposal for trucks and compactor boxes in accordance with the specifications defined by this tender.
The sketch must contain, as a minimum, the following elements:
The Offeror must demonstrate compliance with the provisions of Regulation 100 of the United Nations Economic Commission for Europe (UNECE) on uniform provisions relating to the approval of vehicles in relation to the specific requirements of the group
